Question

Given the following class:

class TestClass {   public void SetValue(int value) { Value = value; }   public int Value { get; set; } } 

I can do

TestClass tc = new TestClass(); Action<int> setAction = tc.SetValue; setAction.Invoke(12); 

which is all good. Is it possible to do the same thing using the property instead of the method? Preferably with something built in to .net.

Answer 1

You could create the delegate using reflection :

Action<int> valueSetter = (Action<int>)Delegate.CreateDelegate(typeof(Action<int>), tc, tc.GetType().GetProperty('Value').GetSetMethod()); 

or create a delegate to an anonymous method which sets the property;

Action<int> valueSetter = v => tc.Value = v; 

Edit: used wrong overload for CreateDelegate(), need to use the one that takes and object as target. Fixed.
