WindowsRuntimeBufferExtensions.CopyTo Method (, UInt32, , UInt32, UInt32)

  • Article

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.

    destination As IBuffer, _
    destinationIndex As UInteger, _
    count As UInteger _
)

[CLSCompliantAttribute(false)]
public static void CopyTo(
    this IBuffer source,
    uint sourceIndex,
    IBuffer destination,
    uint destinationIndex,
