Question

Let’s say I have this method:

public static object CallMethod(Delegate method, params object[] args)
{
    //more logic
    return method.DynamicInvoke(args);
}

This below has worked fine for most scenarios, calling it like so (simple example):

Delegate methodCall = new Func<decimal,decimal>(Math.Ceiling);
object callResult = CallMethod(methodCall, myNumber);

However, I’ve run into a situation where I need to use this on a method that takes in a ‘ref’ parameter (WCF service call), which the Func class can not handle.

Delegate methodCall =
    new Func<MyService.InputClass, MyService.CallResult>(service.DoWork);

Since I don’t have a lot of experience dealing with delegates, what would be the easiest way of creating a delegate for the above method to pass on to mine?

Answer 1

This isn’t my application so I don’t have an easy way of testing it (I was just asked if I knew of a way of resolving the problem), but does this look like it should work?

Delegate methodCall = new Func<MyService.CallResult>(delegate() { return service.DoWork(ref myInput)});
object callResult = CallMethod(methodCall, null);
