您是否嘗試過與此System.Reflection.MethodInfo.GetCurrentMethod（）; – coder 2013-02-23 06:44:22

@coder我不想要當前的方法。我想要所有存在於類Math中的方法 – 2013-02-23 06:45:00

你想在運行時還是設計時使用它？ – 2013-02-23 06:45:07

試試這個：如果您需要了解所有的參數太多，嘗試像

private static void Main() 
    { 
     MethodInfo[] methodInfos = typeof(Math).GetMethods(BindingFlags.Public | BindingFlags.Static); 
     foreach (MethodInfo methodInfo in methodInfos) 
     { 
      Console.WriteLine(String.Format("{0} with following parameters", methodInfo.Name)); 
      ParameterInfo[] parameters = methodInfo.GetParameters(); 
      foreach (ParameterInfo parameter in parameters) 
      { 
       Console.WriteLine("Name : {0}, Type : {1}", parameter.Name, parameter.ParameterType.FullName); 
      } 

      Console.WriteLine("--------------"); 
     } 
    }

的

MethodInfo[] methodInfos = typeof(Math).GetMethods(BindingFlags.Public | BindingFlags.Static); 
    foreach (MethodInfo methodInfo in methodInfos) 
    { 
     Console.WriteLine(methodInfo.Name); 
    }

不錯，但是這個返回成員包括（屬性，方法，字段，事件等等）。 – 2013-02-23 08:46:43

@Mahdi我們可以在一行中做到這一點'：）' – spajce 2013-02-23 08:51:01
