c# - How to get current property name via reflection?

I would like to get property name when I'm in it via reflection mechanism. Is it possible?

Update: I have code like this:

    public CarType Car
    {
        get { return (Wheel) this["Wheel"];}
        set { this["Wheel"] = value; }
    }

And because I need more properties like this I would like to do something like this:

    public CarType Car
    {
        get { return (Wheel) this[GetThisPropertyName()];}
        set { this[GetThisPropertyName()] = value; }
    }

Since properties are really just methods you can do this and clean up the get_ returned:

class Program
    {
        static void Main(string[] args)
        {
            Program p = new Program();
            var x = p.Something;
            Console.ReadLine();
        }

        public string Something
        {
            get
            {
                return MethodBase.GetCurrentMethod().Name;
            }
        }
    }

If you profile the performance you should find MethodBase.GetCurrentMethod() is miles faster than StackFrame. In .NET 1.1 you will also have issues with StackFrame in release mode (from memory I think I found it was 3x faster).

That said I'm sure the performance issue won't cause too much of a problem- though an interesting discussion on StackFrame slowness can be found here.

I guess another option if you were concerned about performance would be to create a Visual Studio Intellisense Code Snippet that creates the property for you and also creates a string that corresponds to the property name.
