If you are not in a console project, you'll see  your console.writeline
statements in the debug Output window.

If you are in a Windows application, you can just create a temporary
messgagebox.show statement to print your value on the screen.

Or, you could just set a breakpoint and check the various debugging
windows/intelliSense features to see your value.

to showup in the vs debugger console just:

    System.Diagnostics.Debug.Write("some text");

also see the Trace class.
