How to get current property name via reflection?

Question

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

Way # 1

var a = nameof(SampleMethod);    //a == SampleMethod
var b = nameof(SampleVariable);  //b == SampleVariable
var c = nameof(SampleProperty);  //c == SampleProperty

Way # 2

MethodBase.GetCurrentMethod().Name; // Name of method in which you call the code
MethodBase.GetCurrentMethod().Name.Replace("set_", "").Replace("get_", ""); // current Property

Way # 3

from StackTrace:

public static class Props
{
    public static string CurrPropName => 
         (new StackTrace()).GetFrame(1).GetMethod().Name.Replace("set_", "").Replace("get_", "");

    public static string CurrMethodName => 
        (new StackTrace()).GetFrame(1).GetMethod().Name;
}

you just need to call Props.CurrPropName or Props.CurrMethodName

Solution for .NET 4.5+:

public static class Props
{
    public static string GetCallerName([System.Runtime.CompilerServices.CallerMemberName] String propertyName = "")
    {
         return propertyName;
    }
}

usgae: Props.GetCallerName();

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.
