Hi Stu,
You can do it in IL because properties are not more then two accessor
methods. As a method it can be used with delegates. However, C# doesn't
support delegates for properties. It doesn't mean you can't do it with C#,
though.
Take a look at the code below
using System;
namespace PropertyDelegate
{
delegate int GetIntAccessorDelegate(); //Deleagte for the Get method
delegate void SetIntAccessorDelegate(int value); //Delegate for the Set
method
//Test class
class Foo
{
private int mVal = 10;
public int Val
{
get
{
return mVal;
}
set
{
mVal = value;
}
}
}
class Class1
{
static Foo mFoo = new Foo();
[STAThread]
static void Main(string[] args)
{
//Creating *get* delegate
GetIntAccessorDelegate getDlgt =
(GetIntAccessorDelegate)Delegate.CreateDelegate(typeof(GetIntAccessorDelegat
e), mFoo, "get_Val");
//Creating *set* delegate
SetIntAccessorDelegate setDlgt =
(SetIntAccessorDelegate)Delegate.CreateDelegate(typeof(SetIntAccessorDelegat
e), mFoo, "set_Val");
Console.WriteLine("mFoo.Val(before) = {0}", getDlgt());
setDlgt(100);
Console.WriteLine("mFoo.Val(after) = {0}", getDlgt());
Console.ReadLine();
}
}
}
