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

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?

Solution 1:

public class SomeClass
{
    public void SomeMethod()
    {
        StackFrame frame = new StackFrame(1);
        var method = frame.GetMethod();
        var type = method.DeclaringType;
        var name = method.Name;
    }
}

Now let's say you have another class like this:

public class Caller
{
   public void Call()
   {
      SomeClass s = new SomeClass();
      s.SomeMethod();
   }
}

name will be "Call" and type will be "Caller".

UPDATE: Two years later since I'm still getting upvotes on this

In .NET 4.5 there is now a much easier way to do this. You can take advantage of the CallerMemberNameAttribute.

Going with the previous example:

public class SomeClass
{
    public void SomeMethod([CallerMemberName]string memberName = "")
    {
        Console.WriteLine(memberName); // Output will be the name of the calling method
    }
}

Solution 2:

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);

Solution 3:

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

Solution 4:

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.
