The Debug class provides a set of methods and properties that help you debug code. Use the Write and WriteLine methods to send text to the debug output window. To see the debug output window, in Microsoft Visual Studio, click View, click Other Windows, and then click Output. You can view the debug output in this window only if the debugger is attached to the process that is writing to the output window.
The text that is displayed in the output window is
sequential, so the text appears in the order that it is received.
Sending text to the output window is most useful for getting
noncritical information. For example, to determine if
Method1 is called before or after
System.Diagnostics.Debug.WriteLine("Method1") at the
System.Diagnostics.Debug.WriteLine("Method2") at the
Method2. The method name that appears
first indicates the method that is called first.
