How do you get a variable’s name as it was physically typed in its declaration? [duplicate]

by

Maybe you need this. Works fine.

I found this here.

static void Main(string[] args)
{
    var domain = "matrix";
    Check(() => domain);
    Console.ReadLine();
}

static void Check<T>(Expression<Func<T>> expr)
{
    var body = ((MemberExpression)expr.Body);
    Console.WriteLine("Name is: {0}", body.Member.Name);
    Console.WriteLine("Value is: {0}", ((FieldInfo)body.Member)
   .GetValue(((ConstantExpression)body.Expression).Value));
}

Output will be:

Name is: 'domain'
Value is: 'matrix'
