也许你正在寻找这样的东西:

StackFrame frame = new StackFrame(1);
frame.GetMethod().Name; //Gets the current method name

MethodBase method = frame.GetMethod();
method.DeclaringType.Name //Gets the current class name

我们可以对阿萨德先生的代码(目前公认的答案)稍加改进，只实例化我们实际需要的帧而不是整个堆栈:

new StackFrame(1).GetMethod().Name;

这可能会执行得更好一些，尽管在所有的可能性中，它仍然需要使用整个堆栈来创建单个帧。此外，它仍然有Alex Lyman指出的同样的警告(优化器/本机代码可能会破坏结果)。最后，你可能想要检查以确保新的StackFrame(1)或. getframe(1)不返回null，因为这种可能性看起来不太可能。

请看这个相关问题: 您可以使用反射来查找当前正在执行的方法的名称吗?

      StackTrace st = new StackTrace();
      StackFrame[] frames = st.GetFrames();
      for (int i = 0; i < st.FrameCount - 1; i++)
      {
         if (frames[i].GetMethod().Name.Equals(MethodAfter))
         {
            if (!frames[i + 1].GetMethod().Name.Equals(MethodAfter)) // ignores overloaded methods.
            {
               str = frames[i + 1].GetMethod().ReflectedType.FullName + "." + frames[i + 1].GetMethod().Name;
               break;
            }
         }
      }
   }
   catch (Exception) { ; }
   return str;
}

显然这是一个迟来的答案，但如果你能使用。net 4.5或更新版本，我有一个更好的选择:

internal static void WriteInformation<T>(string text, [CallerMemberName]string method = "")
{
    Console.WriteLine(DateTime.Now.ToString() + " => " + typeof(T).FullName + "." + method + ": " + text);
}

这将打印当前的日期和时间，后面跟着“Namespace.ClassName”。并以“:text”结尾。 样例输出:

6/17/2016 12:41:49 PM => WpfApplication.MainWindow..ctor: MainWindow initialized

示例使用:

Logger.WriteInformation<MainWindow>("MainWindow initialized");

快速回顾一下这两种方法，速度比较是重要的部分。

在编译时确定调用者

static void Log(object message, 
[CallerMemberName] string memberName = "",
[CallerFilePath] string fileName = "",
[CallerLineNumber] int lineNumber = 0)
{
    // we'll just use a simple Console write for now    
    Console.WriteLine("{0}({1}):{2} - {3}", fileName, lineNumber, memberName, message);
}

使用堆栈确定调用者

static void Log(object message)
{
    // frame 1, true for source info
    StackFrame frame = new StackFrame(1, true);
    var method = frame.GetMethod();
    var fileName = frame.GetFileName();
    var lineNumber = frame.GetFileLineNumber();

    // we'll just use a simple Console write for now    
    Console.WriteLine("{0}({1}):{2} - {3}", fileName, lineNumber, method.Name, message);
}

两种方法的比较

Time for 1,000,000 iterations with Attributes: 196 ms
Time for 1,000,000 iterations with StackTrace: 5096 ms

因此，您可以看到，使用属性要快得多!近25 x 实际上更快。
