To create a delegate from a method you can use the compile-safe syntax:
private int Method() { ... }
// and create the delegate to Method...
Func<int> d = Method;
A property is a wrapper around a getter and setter method, and I want to create a delegate to a property getter method. Something like
public int Prop { get; set; }
Func<int> d = Prop;
// or...
Func<int> d = Prop_get;
Which doesn't work, unfortunately. I have to create a separate lambda method, which seems unnecessary when the setter method matches the delegate signature anyway:
Func<int> d = () => Prop;
In order to use the delegate method directly, I have to use nasty reflection, which isn't compile-safe:
// something like this, not tested...
MethodInfo m = GetType().GetProperty("Prop").GetGetMethod();
Func<int> d = (Func<int>)Delegate.CreateDelegate(typeof(Func<int>), m);
Is there any way of creating a delegate on a property getting method directly in a compile-safe way, similar to creating a delegate on a normal method at the top, without needing to use an intermediate lambda method?
