How to find the FULL name of the calling method in C#

Question

How can I find the full name of a calling method in C#? I have seen solutions:

How I can get the calling methods in C#

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

Get Calling function name from Called function

But they only give me the top level. Consider the example:

namespace Sandbox
{
    class Program
    {
        static void Main(string[] args)
        {
            test();
        }

        static void test()
        {
            var stackTrace = new StackTrace();
            var methodBase = stackTrace.GetFrame(1).GetMethod();
            Console.WriteLine(methodBase.Name);
        }
    }
}

This simply outputs 'Main'. How can I get it to print 'Sandbox.Program.Main'?

It's for a simple logging framework that I am working on.

Adding onto Matzi's Answer:

Here is the solution:

namespace Sandbox
{
    class Program
    {
        static void Main(string[] args)
        {
            test();
        }

        static void test()
        {
            var stackTrace = new StackTrace();
            var methodBase = stackTrace.GetFrame(1).GetMethod();
            var Class = methodBase.ReflectedType;
            var Namespace = Class.Namespace;         // Added finding the namespace
            Console.WriteLine(Namespace + "." + Class.Name + "." + methodBase.Name);
        }
    }
}

It produces 'Sandbox.Program.Main' like it should.

Answer 1

This is something like here .

MethodBase method = stackTrace.GetFrame(1).GetMethod();
string methodName = method.Name;
string className = method.ReflectedType.Name;

Console.WriteLine(className + "." + methodName);

Answer 2

I think the best way to get the full name is:

 this.GetType().FullName + "." + System.Reflection.MethodBase.GetCurrentMethod().Name;

Or try this:

string method = string.Format("{0}.{1}", MethodBase.GetCurrentMethod().DeclaringType.FullName, MethodBase.GetCurrentMethod().Name);

And if you want to display the most recent function call, you can use:

StackTrace st  = new StackTrace();
StackFrame sf  = st.GetFrame(0);
var methodName = sf.GetMethod();

But if you want to display the tree of calling functions, you can do it like this:

if (st.FrameCount >1)
{
     // Display the highest-level function call
     // in the trace.
     StackFrame sf = st.GetFrame(st.FrameCount-1);
     Console.WriteLine("  Original function call at top of call stack):");
     Console.WriteLine("      {0}", sf.GetMethod());
}

With this method you can reliably get the full name

    public void HandleException(Exception ex, [CallerMemberName] string caller = "")
    {
        if (ex != null)
        {
            while (ex.InnerException != null)
                ex = ex.InnerException;

            foreach (var method in new StackTrace().GetFrames())
            {
                if (method.GetMethod().Name == caller)
                {
                    caller = $"{method.GetMethod().ReflectedType.Name}.{caller}";
                    break;
                }
            }

            Console.WriteLine($"Exception: {ex.Message} Caller: {caller}()");
        }
    }

在System.Reflection.MethodBase方法GetCurrentMethod ，您可以使用类等找到有关调用堆栈的完整信息。

Answer 5

The current calling namespace which is not equal as the current namespace:

    var mNamespace = new StackTrace().GetFrames()?.Select(x =>
                {
                    try
                    {
                        return x.GetMethod().ReflectedType?.Namespace;
                    }
                    catch (Exception)
                    {
                        return string.Empty;
                    }
                }).First(x => x != new StackTrace().GetFrame(0).GetMethod().ReflectedType?.Namespace);
