比较获得方法名的方法——在LinqPad中使用任意计时结构:

CODE

void Main()
{
    // from http://blogs.msdn.com/b/webdevelopertips/archive/2009/06/23/tip-83-did-you-know-you-can-get-the-name-of-the-calling-method-from-the-stack-using-reflection.aspx
    // and https://stackoverflow.com/questions/2652460/c-sharp-how-to-get-the-name-of-the-current-method-from-code

    var fn = new methods();

    fn.reflection().Dump("reflection");
    fn.stacktrace().Dump("stacktrace");
    fn.inlineconstant().Dump("inlineconstant");
    fn.constant().Dump("constant");
    fn.expr().Dump("expr");
    fn.exprmember().Dump("exprmember");
    fn.callermember().Dump("callermember");

    new Perf {
        { "reflection", n => fn.reflection() },
        { "stacktrace", n => fn.stacktrace() },
        { "inlineconstant", n => fn.inlineconstant() },
        { "constant", n => fn.constant() },
        { "expr", n => fn.expr() },
        { "exprmember", n => fn.exprmember() },
        { "callermember", n => fn.callermember() },
    }.Vs("Method name retrieval");
}

// Define other methods and classes here
class methods {
    public string reflection() {
        return System.Reflection.MethodBase.GetCurrentMethod().Name;
    }
    public string stacktrace() {
        return new StackTrace().GetFrame(0).GetMethod().Name;
    }
    public string inlineconstant() {
        return "inlineconstant";
    }
    const string CONSTANT_NAME = "constant";
    public string constant() {
        return CONSTANT_NAME;
    }
    public string expr() {
        Expression<Func<methods, string>> ex = e => e.expr();
        return ex.ToString();
    }
    public string exprmember() {
        return expressionName<methods,string>(e => e.exprmember);
    }
    protected string expressionName<T,P>(Expression<Func<T,Func<P>>> action) {
        // https://stackoverflow.com/a/9015598/1037948
        return ((((action.Body as UnaryExpression).Operand as MethodCallExpression).Object as ConstantExpression).Value as MethodInfo).Name;
    }
    public string callermember([CallerMemberName]string name = null) {
        return name;
    }
}

>> winner: constant

注意expr和callermember方法并不完全“正确”。在这里，您可以看到一个重复的相关评论，即反射比stacktrace快15倍。

这个怎么样:

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

在空控制台程序的Main方法中试试这个:

MethodBase method = MethodBase.GetCurrentMethod();
Console.WriteLine(method.Name);

控制台输出: 主要

为了同时处理异步和普通的旧方法调用，我这样做了。

在我的应用程序中，它只从异常处理程序调用，所以性能不是一个问题。

[MethodImpl(MethodImplOptions.NoInlining)]
public static string GetCurrentMethodName()
{
    var st = new StackTrace();
    var sf = st.GetFrame(1);
    string name = sf.GetMethod().Name;

    if (name.Equals("MoveNext"))
    {
        // We're inside an async method
        name = sf.GetMethod().ReflectedType.Name
                 .Split(new char[] { '<', '>' }, StringSplitOptions.RemoveEmptyEntries)[0];
    }

    return name;
}

从2021年到2022年，为客户提供更具弹性的解决方案:

namespace my {
   public struct notmacros
   {

[MethodImpl(MethodImplOptions.AggressiveInlining)]
public static string 
  whoami( [CallerMemberName] string caller_name = null)
  {
     if (string.IsNullOrEmpty(caller_name)) 
        return "unknown";
     if (string.IsNullOrWhiteSpace(caller_name)) 
        return "unknown";
     return caller_name;
  }
 }
} // my namespace

使用

using static my.notmacros
 // somewhere  appropriate
 var my_name = whoami() ;

请注意编译器要求:.NET 6

对于可以使用的非异步方法

System.Reflection.MethodBase.GetCurrentMethod().Name;

https://learn.microsoft.com/en-us/dotnet/api/system.reflection.methodbase.getcurrentmethod

请记住，对于异步方法，它将返回“MoveNext”。
