This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Provides access to unmanaged blocks of memory from managed code.

System.Object
  System.IO.Stream
    System.IO.UnmanagedMemoryStream

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)
public class UnmanagedMemoryStream : Stream

The UnmanagedMemoryStream type exposes the following members.
