Parameters

buffer

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

index

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

count

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

Exceptions

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

Remarks

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

Note: The new stream instance can be written to, 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 .
