[c#] How do I get the calling method name and type using reflection?

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

I'd like to write a method which obtains the name of the calling method, and the name of the class containing the calling method.

Is it possible with C# reflection?

You can use it by using the StackTrace and then you can get reflective types from that.

StackTrace stackTrace = new StackTrace();           // get call stack
StackFrame[] stackFrames = stackTrace.GetFrames();  // get method calls (frames)

StackFrame callingFrame = stackFrames[1];
MethodInfo method = callingFrame.GetMethod();
Console.Write(method.Name);
Console.Write(method.DeclaringType.Name);

Technically, you can use StackTrace, but this is very slow and will not give you the answers you expect a lot of the time. This is because during release builds optimizations can occur that will remove certain method calls. Hence you can't be sure in release whether stacktrace is "correct" or not.

Really, there isn't any foolproof or fast way of doing this in C#. You should really be asking yourself why you need this and how you can architect your application, so you can do what you want without knowing which method called it.

It's actually something that can be done using a combination of the current stack-trace data, and reflection.

public void MyMethod()
{
     StackTrace stackTrace = new System.Diagnostics.StackTrace();
     StackFrame frame = stackTrace.GetFrames()[1];
     MethodInfo method = frame.GetMethod();
     string methodName = method.Name;
     Type methodsClass = method.DeclaringType;
}

The 1 index on the StackFrame array will give you the method which called MyMethod

Yes, in principe it is possible, but it doesn't come for free.

You need to create a StackTrace, and then you can have a look at the StackFrame's of the call stack.
