How can I find the method that called the current method?

Question

When logging in C#, how can I learn the name of the method that called the current method? I know all about System.Reflection.MethodBase.GetCurrentMethod(), but

As of .NET 4.5 you can use Caller Information Attributes:

• CallerFilePath - The source file that called the function;
• CallerLineNumber - Line of code that called the function;

• CallerMemberName - Member that called the function.

  public void WriteLine(
      [CallerFilePath] string callerFilePath = "", 
      [CallerLineNumber] long callerLineNumber = 0,
      [CallerMemberName] string callerMember= "")
  {
      Debug.WriteLine(
          "Caller File Path: {0}, Caller Line Number: {1}, Caller Member: {2}", 
          callerFilePath,
          callerLineNumber,
          callerMember);
  }
  

 

This facility is also present in ".NET Core" and ".NET Standard".
