How to know method name dynamically with sender or EventArgs object

Question

Hello All,
I am working in ASP.NET. I wanna log method name in log file whenever that method is executed. e.g.
protected void Page_Load(object sender, EventArgs e)
Trace.Log("Page_Load start");
Trace.Log("Page_Load end");
protected void Method2(object sender, EventArgs e)
Trace.Log("Method2 start");
Trace.Log("Method2 end");
Trace.Log() is use to log my string in log files at D:\. Now, here I have hard coded Method name in Trace.Log(). But, now I want to fetch method name via c# code. Can we achieve it via sender or EventArgs object?
Please assist.
Thanks, Chintan

Hello Chintan,
You can get class name through reflection as it gets STATIC info about the component.
However, to get the line number of an exception, which is a run time parameter, you cannot use reflection.
I actually have not tried this before but, given it did not work for you in the web part class, you may try the below code in your *.ascx.cs user control used by your visual web part.
//To Retrieve class name use this line:
string className = this.GetType().FullName;
// To retrieve other parameters including line number
try
TestFunction();
catch (Exception ex)
StackTrace st = new StackTrace(ex, true);
StackFrame[] frames = st.GetFrames();
// Iterate over the frames extracting the information you need
foreach (StackFrame frame in frames)
string stkFrame = string.Format("{0}:{1}({2},{3})", frame.GetFileName(), frame.GetMethod().Name, frame.GetFileLineNumber(), frame.GetFileColumnNumber());
