C# byte sequence mapping

It would be nice if the C# mapping for byte sequences could be optionally specified to map to a range within an array (similar to the C++ mapping options). That way one could avoid extra copying.

.NET even defines the ArraySegment type, but this is not strictly required here.

Maybe I should explain a little. The following Slice

interface Receiver {
  void Receive(long offset, ByteSeq data);
};

generates C# code like this:

[_System.CodeDom.Compiler.GeneratedCodeAttribute("slice2cs", "3.4.1")]
public interface ReceiverPrx : Ice.ObjectPrx
{
    void Receive(long offset, byte[] data);
    void Receive(long offset, byte[] data, _System.Collections.Generic.Dictionary<string, string> context__);

    Ice.AsyncResult<KdSoftIce.Stream.Callback_Receiver_Receive> begin_Receive(long offset, byte[] data);
    Ice.AsyncResult<KdSoftIce.Stream.Callback_Receiver_Receive> begin_Receive(long offset, byte[] data, _System.Collections.Generic.Dictionary<string, string> ctx__);

    Ice.AsyncResult begin_Receive(long offset, byte[] data, Ice.AsyncCallback cb__, object cookie__);
    Ice.AsyncResult begin_Receive(long offset, byte[] data, _System.Collections.Generic.Dictionary<string, string> ctx__, Ice.AsyncCallback cb__, object cookie__);

    void end_Receive(Ice.AsyncResult r__);
}

It would be helpful if it would also (optionally) generate this:

public interface ReceiverPrx : Ice.ObjectPrx
{
    ...
    void Receive(long offset, byte[] data, int start, int count);
       // or maybe
    void Receive(long offset, ArraySegment<byte> data);
    ...
}
