Windows.Storage.FileIO.WriteBufferAsync

-description

-parameters

-param file

The file that the buffer of data is written to.

-param buffer

The buffer that contains the data to write.

-returns

No object or value is returned when this method completes.

-remarks

-examples

The File Access sample shows you how to use WriteBufferAsync to write data from a buffer to a file.

try
{
    if (file != null)
    {
        IBuffer buffer = CryptographicBuffer.GenerateRandom(10);
        await FileIO.WriteBufferAsync(file, buffer);
        // Perform additional tasks after file is written
    }
}
// Handle errors with catch blocks
catch (FileNotFoundException)
{
    // For example, handle file not found
}

In the example, file is a local variable that contains a StorageFile that represents the file to write.

Although the WriteBufferAsync methods don't have a return value, you can still perform additional tasks after the text is written to the file, as the example shows.
