XML-RPC.NET and C# Dynamic Types

Question

The Cook Computing blog has a post discussing how dynamics in .NET 4 could be used to create dynamic RPC calls. (Post: ALTERNATIVE SYNTAX FOR MEMBER CALLS ON C# DYNAMIC TYPES )

The post shows the following example:

using System.Dynamic;

class XmlRpcClient : DynamicObject
{
  string endpoint;

  public XmlRpcClient(string endpoint)
  {
    this.endpoint = endpoint;
  }

  public object Invoke(string methodName, object[] args)
  {
    return 5; // actually make call to XML-RPC endpoint here
  }

  public override bool TryInvokeMember(InvokeMemberBinder binder, object[] args, 
    out object result)
  {
    result = Invoke(binder.Name, args);
    return true;
  }
}

The part I don't understand is the comment stating "actually make call to XML-RPC endpoint here".

Is there a way to use the XML-RPC.NET library in the invoke method or would you need to make a HttpWebRequest call?

Thanks

Answer 1

When I wrote the post "Alternative Syntax…" dynamic support in C# had only just been announced so I was just describing a possible implementation to take advantage of these new features.

Implementing "actually make call to XML-RPC endpoint here" would require a call to the XmlRpcClientProtocol class though this class would need some minor modifications to be used in this way.
