How to print the current Stack Trace in .NET without any exception?

Have a look at the System.Diagnostics namespace. Lots of goodies in there!

System.Diagnostics.StackTrace t = new System.Diagnostics.StackTrace();

This is really good to have a poke around in to learn what's going on under the hood.

I'd recommend that you have a look into logging solutions (Such as NLog, log4net or the Microsoft patterns and practices Enterprise Library) which may achieve your purposes and then some.

There are two ways to do this. The System.Diagnostics.StackTrace() will give you a stack trace for the current thread. If you have a reference to a Thread instance, you can get the stack trace for that via the overloaded version of StackTrace().

Console.WriteLine(
    new System.Diagnostics.StackTrace().ToString()
    );

The output will be similar to:

at YourNamespace.Program.executeMethod(String msg)

at YourNamespace.Program.Main(String[] args)

Replace Console.WriteLine with your Log method. Actually, there is no need for .ToString() for the Console.WriteLine case as it accepts object. But you may need that for your Log(string msg) method.

This worked for me:

Debug.WriteLine(Environment.StackTrace);

   private void ExceptionTest()
    {
        try
        {
            int j = 0;
            int i = 5;
            i = 1 / j;
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex.Message);
            var stList = ex.StackTrace.ToString().Split('\\');
            Console.WriteLine("Exception occurred at " + stList[stList.Count() - 1]);
        }
    }

Seems to work for me
