Parameters

buffer

The byte array from which to create the new stream. [Edit]

index

A int that specifies the index in buffer at which the stream begins. [Edit]

count

A int that specifies the length of the stream in bytes. [Edit]

writable

A bool that specifies whether the new stream instance supports writing. [Edit]

Exceptions

Type	Reason
ArgumentNullException	buffer is null. [Edit]
ArgumentOutOfRangeException	index or count are negative. [Edit]
ArgumentException	(index + count ) is greater than the length of buffer. [Edit]

Remarks

The MemoryStream.CanRead and MemoryStream.CanSeek properties of the new System.IO.MemoryStream are set to true. The MemoryStream.Capacity property is set to count. The Stream.CanWrite property is set to writable.

Note: The new stream instance can be written to depending on the value of writable, but the MemoryStream.Capacity of the underlying byte array cannot be changed. The length of the stream cannot be set to a value larger than MemoryStream.Capacity, but the stream can be truncated (see MemoryStream.SetLength(long)).

The new stream does not expose the underlying byte buffer, and calls to the MemoryStream.GetBuffer method throw UnauthorizedAccessException.
