<summary>Lets you efficiently bulk load a SQL Server table with data from another source.</summary>
<remarks>
<format type="text/markdown"><![CDATA[
## Remarks
Microsoft SQL Server includes a popular command-prompt utility named **bcp** for moving data from one table to another, whether on a single server or between servers. The <xref:System.Data.SqlClient.SqlBulkCopy> class lets you write managed code solutions that provide similar functionality. There are other ways to load data into a SQL Server table (INSERT statements, for example), but <xref:System.Data.SqlClient.SqlBulkCopy> offers a significant performance advantage over them.
The <xref:System.Data.SqlClient.SqlBulkCopy> class can be used to write data only to SQL Server tables. However, the data source is not limited to SQL Server; any data source can be used, as long as the data can be loaded to a <xref:System.Data.DataTable> instance or read with a <xref:System.Data.IDataReader> instance.
<xref:System.Data.SqlClient.SqlBulkCopy> will fail when bulk loading a <xref:System.Data.DataTable> column of type <xref:System.Data.SqlTypes.SqlDateTime> into a SQL Server column whose type is one of the date/time types added in SQL Server 2008.
## Examples
The following console application demonstrates how to load data using the <xref:System.Data.SqlClient.SqlBulkCopy> class. In this example, a <xref:System.Data.SqlClient.SqlDataReader> is used to copy data from the **Production.Product** table in the SQL Server **AdventureWorks** database to a similar table in the same database.
> [!IMPORTANT]
> This sample will not run unless you have created the work tables as described in [Bulk Copy Example Setup](/dotnet/framework/data/adonet/sql/bulk-copy-example-setup). This code is provided to demonstrate the syntax for using **SqlBulkCopy** only. If the source and destination tables are in the same SQL Server instance, it is easier and faster to use a Transact-SQL `INSERT ... SELECT` statement to copy the data.

<param name="connection">The already open <see cref="T:System.Data.SqlClient.SqlConnection" /> instance that will be used to perform the bulk copy operation. If your connection string does not use <see langword="Integrated Security = true" />, you can use <see cref="T:System.Data.SqlClient.SqlCredential" /> to pass the user ID and password more securely than by specifying the user ID and password as text in the connection string.</param>
<summary>Initializes a new instance of the <see cref="T:System.Data.SqlClient.SqlBulkCopy" /> class using the specified open instance of <see cref="T:System.Data.SqlClient.SqlConnection" />.</summary>
<remarks>
<format type="text/markdown"><![CDATA[
## Remarks
Because the connection is already open when the <xref:System.Data.SqlClient.SqlBulkCopy> instance is initialized, the connection remains open after the <xref:System.Data.SqlClient.SqlBulkCopy> instance is closed.
If the `connection` argument is null, an <xref:System.ArgumentNullException> is thrown.
## Examples
The following console application demonstrates how to bulk load data using a connection that is already open. In this example, a <xref:System.Data.SqlClient.SqlDataReader> is used to copy data from the **Production.Product** table in the SQL Server **AdventureWorks** database to a similar table in the same database. This example is for demonstration purposes only. You would not use `SqlBulkCopy` to move data from one table to another in the same database in a production application.

## Remarks
You can obtain detailed information about all the bulk copy options in the <xref:System.Data.SqlClient.SqlBulkCopyOptions> topic.
## Examples
The following console application demonstrates how to perform a bulk load by using a connection specified as a string. An option is set to use the value in the identity column of the source table when you load the destination table. In this example, the source data is first read from a SQL Server table to a <xref:System.Data.SqlClient.SqlDataReader> instance. The source table and destination table each include an Identity column. By default, a new value for the **Identity** column is generated in the destination table for each row added. In this example, an option is set when the connection is opened that forces the bulk load process to use the **Identity** values from the source table instead. To see how the option changes the way the bulk load works, run the sample with the **dbo.BulkCopyDemoMatchingColumns** table empty. All rows load from the source. Then run the sample again without emptying the table. An exception is thrown and the code writes a message to the console notifying you that rows weren't added because of primary key constraint violations.

## Remarks
After you call a <xref:System.Data.SqlClient.SqlBulkCopy.Close%2A> on the <xref:System.Data.SqlClient.SqlBulkCopy> object, no other operation will succeed. Calls to the <xref:System.Data.SqlClient.SqlBulkCopy.WriteToServer%2A> method will throw an <xref:System.InvalidOperationException>.
Calling the <xref:System.Data.SqlClient.SqlBulkCopy.Close%2A> method from the <xref:System.Data.SqlClient.SqlBulkCopy.SqlRowsCopied> event causes an <xref:System.InvalidOperationException> to be thrown.
Note that open <xref:System.Data.SqlClient.SqlBulkCopy> instances are closed implicitly at the end of a `using` block.
## Examples
The following example uses the same <xref:System.Data.SqlClient.SqlBulkCopy> instance to add sales orders and their associated details to two destination tables. Because the **AdventureWorks** sales order tables are large, the sample reads only orders placed by a certain account number and bulk copies those orders and details to the destination tables. The <xref:System.Data.SqlClient.SqlBulkCopy.Close%2A> method is used only after both bulk copy operations are complete.

If <xref:System.Data.SqlClient.SqlBulkCopy.DestinationTableName%2A> is modified while a <xref:System.Data.SqlClient.SqlBulkCopy.WriteToServer%2A> operation is running, the change does not affect the current operation. The new <xref:System.Data.SqlClient.SqlBulkCopy.DestinationTableName%2A> value is used the next time a <xref:System.Data.SqlClient.SqlBulkCopy.WriteToServer%2A> method is called.
<xref:System.Data.SqlClient.SqlBulkCopy.DestinationTableName%2A> is a three-part name (`<database>.<owningschema>.<name>`). You can qualify the table name with its database and owning schema if you choose. However, if the table name uses an underscore ("_") or any other special characters, you must escape the name using surrounding brackets as in (`[<database>.<owningschema>.<name_01>]`). For more information, see [Database Identifiers](/sql/relational-databases/databases/database-identifiers).
You can bulk-copy data to a temporary table by using a value such as `tempdb..#table` or `tempdb.<owner>.#table` for the <xref:System.Data.SqlClient.SqlBulkCopy.DestinationTableName%2A> property.
## Examples
The following console application demonstrates how to bulk load data using a connection that is already open. The destination table is a table in the **AdventureWorks** database.
In this example, the connection is first used to read data from a SQL Server table to a <xref:System.Data.SqlClient.SqlDataReader> instance. The source data does not have to be located on SQL Server; you can use any data source that can be read to an <xref:System.Data.IDataReader> or loaded to a <xref:System.Data.DataTable>.
> [!IMPORTANT]
> This sample will not run unless you have created the work tables as described in [Bulk Copy Example Setup](/dotnet/framework/data/adonet/sql/bulk-copy-example-setup). This code is provided to demonstrate the syntax for using **SqlBulkCopy** only. If the source and destination tables are in the same SQL Server instance, it is easier and faster to use a Transact-SQL `INSERT ... SELECT` statement to copy the data.

## Remarks
This property is designed for user interface components that illustrate the progress of a bulk copy operation. It indicates the number of rows to be processed before generating a notification event. The <xref:System.Data.SqlClient.SqlBulkCopy.NotifyAfter%2A> property can be set at any time, even while a bulk copy operation is underway. Changes made during a bulk copy operation take effect after the next notification. The new setting applies to all subsequent operations on the same instance.
If <xref:System.Data.SqlClient.SqlBulkCopy.NotifyAfter%2A> is set to a number less than zero, an <xref:System.ArgumentOutOfRangeException> is thrown.
## Examples
The following console application demonstrates how to bulk load data using a connection that is already open. The <xref:System.Data.SqlClient.SqlBulkCopy.NotifyAfter%2A> property is set so that the event handler is called after every 50 rows copied to the table.
In this example, the connection is first used to read data from a SQL Server table to a <xref:System.Data.SqlClient.SqlDataReader> instance. Then a second connection is opened to bulk copy the data. Note that the source data does not have to be located on SQL Server; you can use any data source that can be read to an <xref:System.Data.IDataReader> or loaded to a <xref:System.Data.DataTable>.

## Remarks
The copy operation starts at the next available row in the reader. Most of the time, the reader was just returned by <xref:System.Data.IDbCommand.ExecuteReader%2A> or a similar call, so the next available row is the first row. To process multiple results, call <xref:System.Data.IDataReader.NextResult%2A> on the data reader and call <xref:System.Data.SqlClient.SqlBulkCopy.WriteToServer%2A> again.
Note that using <xref:System.Data.SqlClient.SqlBulkCopy.WriteToServer%2A> modifies the state of the reader. The method will call <xref:System.Data.IDataReader.Read%2A> until it returns false, the operation is aborted, or an error occurs. This means that the data reader will be in a different state, probably at the end of the result set, when the <xref:System.Data.SqlClient.SqlBulkCopy.WriteToServer%2A> operation is complete.
While the bulk copy operation is in progress, the associated destination <xref:System.Data.SqlClient.SqlConnection> is busy serving it, and no other operations can be performed on the connection.
The <xref:System.Data.SqlClient.SqlBulkCopy.ColumnMappings%2A> collection maps from the data reader columns to the destination database table.
## Examples
The following console application demonstrates how to bulk load data from a <xref:System.Data.SqlClient.SqlDataReader>. The destination table is a table in the **AdventureWorks** database.
> [!IMPORTANT]
> This sample will not run unless you have created the work tables as described in [Bulk Copy Example Setup](/dotnet/framework/data/adonet/sql/bulk-copy-example-setup). This code is provided to demonstrate the syntax for using **SqlBulkCopy** only. If the source and destination tables are in the same SQL Server instance, it is easier and faster to use a Transact-SQL `INSERT ... SELECT` statement to copy the data.
