<summary>Creates a stream whose backing store is memory.</summary>
<remarks>
<format type="text/markdown"><]
Memory streams created with an unsigned byte array provide a non-resizable stream of the data. When using a byte array, you can neither append to nor shrink the stream, although you might be able to modify the existing contents depending on the parameters passed into the constructor. Empty memory streams are resizable, and can be written to and read from.
If a <xref:System.IO.MemoryStream> object is added to a ResX file or a .resources file, call the <xref:System.Resources.ResourceManager.GetStream%2A> method at runtime to retrieve it.
If a <xref:System.IO.MemoryStream> object is serialized to a resource file it will actually be serialized as an <xref:System.IO.UnmanagedMemoryStream>. This behavior provides better performance, as well as the ability to get a pointer to the data directly, without having to go through <xref:System.IO.Stream> methods.
## Examples
The following code example shows how to read and write data using memory as a backing store.

## Remarks
The <xref:System.IO.MemoryStream.CanRead%2A>, <xref:System.IO.MemoryStream.CanSeek%2A>, and <xref:System.IO.MemoryStream.CanWrite%2A> properties are all set to `true`.
The capacity automatically increases when you use the <xref:System.IO.MemoryStream.SetLength%2A> method to set the length to a value larger than the capacity of the current stream. Except for a `MemoryStream` constructed with a byte[] parameter, write operations at the end of a `MemoryStream` expand the `MemoryStream`.
This constructor exposes the underlying stream that <xref:System.IO.MemoryStream.GetBuffer%2A> returns.
## Examples
This code example is part of a larger example provided for the <xref:System.IO.MemoryStream> class.

## Remarks
If a class derived from <xref:System.IO.Stream> does not support writing, a call to <xref:System.IO.Stream.SetLength%2A>, <xref:System.IO.Stream.Write%2A>, or <xref:System.IO.Stream.WriteByte%2A> throws a <xref:System.NotSupportedException>.
If the stream is closed, this property returns `false`.
