How Can I Get the Calling Method's Name and Class Name Using C# Reflection?

Retrieving Calling Method Details Using Reflection

When embarking on the task of obtaining information about the calling method, you may encounter a need to learn the calling method's name and the containing class's name. C# reflection empowers you with the ability to gather these details effectively.

To achieve this, craft a method that utilizes the StackFrame class. Instantiate a StackFrame object with a parameter of 1, representing the calling method. Subsequently, invoke the GetMethod() method on the stack frame to retrieve the calling method's information. The DeclaringType property provides access to the calling method's containing class, and the Name property yields the name of the calling method.

For example, consider the following code snippet:

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

In conjunction with the calling method, this code enables access to its containing class's name via the type variable and to the calling method's name through the name variable.

In .NET 4.5, the CallerMemberNameAttribute provides an alternative, simplified approach. Employing it entails introducing a parameter to the method and annotating it with the [CallerMemberName] attribute:

public void SomeMethod([CallerMemberName]string memberName = "")

Here, the memberName parameter will automagically populate with the calling method's name.
