[c#] How to print the current Stack Trace in .NET without any exception?

I have a regular C# code. I have no exceptions. I want to programmatically log the current stack trace for debugging purpose. Example:

public void executeMethod() 
{
    logStackTrace();
    method();
}

An alternative to System.Diagnostics.StackTrace is to use System.Environment.StackTrace which returns a string-representation of the stacktrace.

Another useful option is to use the $CALLER and $CALLSTACK debugging variables in Visual Studio since this can be enabled run-time without rebuilding the application.

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().

You can also do this in the Visual Studio debugger without modifying the code.

1. Create a breakpoint where you want to see the stack trace.
2. Right-click the breakpoint and select "Actions..." in VS2015. In VS2010, select "When Hit...", then enable "Print a message".
3. Make sure "Continue execution" is selected.
4. Type in some text you would like to print out.
5. Add $CALLSTACK wherever you want to see the stack trace.
6. Run the program in the debugger.

Of course, this doesn't help if you're running the code on a different machine, but it can be quite handy to be able to spit out a stack trace automatically without affecting release code or without even needing to restart the program.

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.

   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
