For apps that target Windows Phone OS 7.0 and 7.1, do not use any members of this type in your app. If you do, your code will throw a MethodAccessException. This type is security-critical, which restricts it to internal use by the .NET Framework for Windows Phone class library.

Copies bytes from the source array to the destination buffer (Windows.Storage.Streams.IBuffer), specifying the starting index in the source array, the starting index in the destination buffer, and the number of bytes to copy. The method does not update the Length property of the destination buffer.
