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

using System;
                    
public class Program
{
    public static void Main()
    {
        
        Console.WriteLine("1: {0} {1}", System.Reflection.MethodBase.GetCurrentMethod().Name, System.Reflection.MethodBase.GetCurrentMethod().ReflectedType);
        OtherMethod();
    }
    
    public static void OtherMethod()
    {
        Console.WriteLine("2: {0} {1}", System.Reflection.MethodBase.GetCurrentMethod().Name, System.Reflection.MethodBase.GetCurrentMethod().ReflectedType);
    }
}

输出:

1: Main Program
2: OtherMethod Program

从。net 4.5开始，你也可以使用[CallerMemberName]。

示例:一个属性setter(回答第2部分):

protected void SetProperty<T>(T value, [CallerMemberName] string property = null)
{
    this.propertyValues[property] = value;
    OnPropertyChanged(property);
}

public string SomeProperty
{
    set { SetProperty(value); }
}

编译器将在调用点提供匹配的字符串字面量，因此基本上没有性能开销。

将此方法添加到某个地方，并不带参数地调用它!

public static string GetCurrentMethodName([System.Runtime.CompilerServices.CallerMemberName] string name = "")
{
    return name;
}

试试这个…

    /// <summary>
    /// Return the full name of method
    /// </summary>
    /// <param name="obj">Class that calls this method (use Report(this))</param>
    /// <returns></returns>
    public string Report(object obj)
    {
        var reflectedType = new StackTrace().GetFrame(1).GetMethod().ReflectedType;
        if (reflectedType == null) return null;

        var i = reflectedType.FullName;
        var ii = new StackTrace().GetFrame(1).GetMethod().Name;

        return string.Concat(i, ".", ii);
    }

对于异步方法，你可以使用:

//using System.Reflection;

var myMethodName = MethodBase
                    .GetCurrentMethod()
                    .DeclaringType
                    .Name
                    .Substring(1)
                    .Split('>')[0];
