方法一：

  1. public static class MemberInfoGetting
  2. {
  3.      public static string GetMemberName<T>(Expression<Func<T>> memberExpression)
  4.      {
  5.          MemberExpression expressionBody = (MemberExpression)memberExpression.Body;
  6.          return expressionBody.Member.Name;
  7.      }
  8. }
  10. string TableName = "123";
  11. string nameOfTestVariable = MemberInfoGetting.GetMemberName(() => TableName);
  13. //最后得到 nameOfTestVariable  = "TableName"

方法二：

  1. static void Main(string[] args) 
  2. {
  3.   GetName(new { var1 });
  4.   GetName2(() => var1);
  5.   GetName3(() => var1);
  6. }
  8. static string GetName<T>(T item) where T : class 
  9. {
  10.   return typeof(T).GetProperties()[0].Name;
  11. }
  13. static string GetName2<T>(Expression<Func<T>> expr) 
  14. {
  15.   return ((MemberExpression)expr.Body).Member.Name;
  16. }
  18. static string GetName3<T>(Func<T> expr) 
  19. {
  20.   return expr.Target.GetType().Module.ResolveField(BitConverter.ToInt32(expr.Method.GetMethodBody().GetILAsByteArray(), 2)).Name;
  21. }
