Question

I have a method with this signature, and another method that will be the used as the Action

ProcessFile(Uri uri, Action<Uri> callWhenDone);

void WhenDone(Uri uri);

Now I’m trying to use the Invoke method on MethodInfo (msdn). But parameters is and object array. Which does not accept a ‘method group’.

var methodInfo = myClass.GetType().GetMethod("nameOfMethod");

var methodParams = new object { new Uri(), WhenDone }; //<-- unable to just do this

methodInfo.Invoke(myClass, methodParams);

How do I pass the method group, or a delegate to the method ProcessFile using Invoke or similar?

Answer 1

try this:

var methodParams = new object { new Uri(), (Action<Uri>)((u) => WhenDone(u)) }; 

or

var methodParams = new object { new Uri(), (Action<Uri>)WhenDone };
