 1 class Program
 2     {
 3         static void Main(string[] args)
 4         {
 5             Person p = new Person();
 6             string name = ReflectionUtility.GetPropertyName(() => p.Age);
 7         }

10         {
11             public static string GetPropertyName<T>(Expression<Func<T>> expression)
12             {
13                 MemberExpression body = (MemberExpression)expression.Body;
14 
15                 return body.Member.ReflectedType.Name + "." + body.Member.Name;
16             }
17         } 
18     }
