Hi Tony,
Since each thread has its own stack, StackTrace will work in multiple
threads just as it does in single thread. Here I have a demo, you may
create a new C# Windows application project, and modify Form1.cs as follows.
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Threading;
using System.Diagnostics;
namespace test1
{
/// <summary>
/// Summary description for Form1.
/// </summary>
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1;
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.Container components = null;
public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeComponent();
//
// TODO: Add any constructor code after
InitializeComponent call
//
}
/// <summary>
/// Clean up any resources being used.
/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}
private void HI()
{
System.Diagnostics.StackTrace st = new
System.Diagnostics.StackTrace(1);
System.Diagnostics.StackFrame sf = st.GetFrame(0);
string msg = sf.GetMethod().DeclaringType.FullName
+ "." +
sf.GetMethod().Name;
MessageBox.Show(msg);
}
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
this.SuspendLayout();
//
// button1
//
this.button1.Location = new
System.Drawing.Point(80, 216);
this.button1.Name = "button1";
this.button1.TabIndex = 0;
this.button1.Text = "button1";
this.button1.Click += new
System.EventHandler(this.button1_Click);
//
// Form1
//
this.AutoScaleBaseSize = new System.Drawing.Size(5,
13);
this.ClientSize = new System.Drawing.Size(292,
273);
this.Controls.Add(this.button1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
}
#endregion
public void test()
{
HI();
}
public void test2()
{
HI();
}
/// <summary>
/// The main entry point for the application.
/// </summary>
static void Main()
{
Application.Run(new Form1());
}
private void button1_Click(object sender, System.EventArgs
e)
{
Thread InstanceCaller = new Thread(new
ThreadStart(this.test));
// Start the thread.
InstanceCaller.Start();
Thread StaticCaller = new Thread(new
ThreadStart(this.test2));
// Start the thread.
StaticCaller.Start();
}
}
}
Hope this will help you.

does anyone think that there any side effect towards this approach such as how
would it works in multi-thread.
Multithreading shouldn't have any effect. Things which might:
o JIT inlining could remove some stack frames
o This method may well slow things down considerably - don't try to use
it in intensive code
