Finding the variable name passed to a function

Question

Let me use the following example to explain my question:

public string ExampleFunction(string Variable) {
    return something;
}

string WhatIsMyName = "         


        

Answer 1

Do this

var myVariable = 123;
myVariable.Named(() => myVariable);
var name = myVariable.Name();
// use name how you like

or naming in code by hand

var myVariable = 123.Named("my variable");
var name = myVariable.Name();

using this class

public static class ObjectInstanceExtensions
{
    private static Dictionary namedInstances = new Dictionary();

    public static void Named(this T instance, Expression> expressionContainingOnlyYourInstance)
    {
        var name = ((MemberExpression)expressionContainingOnlyYourInstance.Body).Member.Name;
        instance.Named(name);            
    }

    public static T Named(this T instance, string named)
    {
        if (namedInstances.ContainsKey(instance)) namedInstances[instance] = named;
        else namedInstances.Add(instance, named);
        return instance;
    }        

    public static string Name(this T instance)
    {
        if (namedInstances.ContainsKey(instance)) return namedInstances[instance];
        throw new NotImplementedException("object has not been named");
    }        
}

Code tested and most elegant I can come up with.
