C# Dynamic indexer

Does anybody know if it's possible to call method on CLR object via indexer using dynamic lang features? For instance, myClrObj["SuperMethod"] () which I can easily do in javascript.

thank in advance.

There may be better ways, but one way I'd know how to do it is:

  • Create a class that inherits from DynamicObject
  • override the suitable method to capture the access via indexer
  • Construct and cache a delegate that corresponds to the method that you find via the provided indexer argument
  • Provide an extension method that suitably makes your object appear dynamic, with the correct DynamicObject specialization instantiated.

    dynamic obj = myObj.AsIndexedObj(); obj["Do"]();
