CopyTo Method (Byte[], Int32, , UInt32, Int32)

WindowsRuntimeBufferExtensions.CopyTo Method (Byte[], Int32, , UInt32, Int32)

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.
