Delegates

I just remembered another technique for calling methods discovered via reflection! It is possible to convert a MethodInfo to a delegate and call it, this is just as fast as calling the method directly. So if you have a method that you call often which was discovered via reflection you should try this….

private delegate bool DoSomethingDelegate(object a, object b);

MethodInfo methodInfo = type.GetMethod(.........);
DoSomethingDelegate method =
  (DoSomethingDelegate)
    Delegate.CreateDelegate(typeof(DoSomethingDelegate), methodInfo);

for (int i = 0; i < 1000000, i++)
  method(this, this);
