Create delegate via reflection

Question

Given an assembly that contains

namespace Foo{public class Bar;}

How could I create an Action<Foo.Bar> from another assembly without referencing the first assembly at compile time?

Answer 1

If you use

Type barType = Type.GetType("Foo.Bar, whateverassembly");
Type actionType = typeof(Action<>).MakeGenericType(barType);

actionType will now represent Action<Foo.Bar>. However, to use it, you'll need to contintue to use reflection, so you'll need to find a MethodInfo that fits the signature void(Foo.Bar), and call Delegate.CreateDelegate to create a delegate. And you'll need Delegate.DynamicInvoke to execute it.

Delegate call = Delegate.CreateDelegate(actionType, ...);
...
call.DynamicInvoke(someBar);

Something tells me that's not what you're thinking of...
