Difference between Debug.Write and Trace.Write in ASP.NET

Question

Hi Friends What is the difference between Debug.Write and Trace.Write? When should each be used?

Prabhu Raja · Answer

Hi, Debug and trace enables you to monitor the application for errors and exception without VS.NET IDE. In Debug mode compiler inserts some debugging code inside the executable. As the debugging code is the part of the executable they run on the same thread where the code runs and they do not given you the exact efficiency of the code (as they run on the same thread). So for every full executable DLL you will see a debug file also as shown in figure 'Debug Mode'. Trace works in both debug as well as release mode. The main advantage of using trace over debug is to do performance analysis which can not be done by debug. Trace runs on a different thread thus it does not impact the main code thread.

Both of these methods are useful for printing out diagnostic information whilst debugging an application. The difference is that (by default) Trace.Write works in both debug and release builds. Debug.Write only works in debug builds. For more details, check out this article: http://www.c-sharpcorner.com/uploadfile/puranindia/debugging-and-tracing-in-C-Sharp/

Normal 0 Hi Akshay, Debug.Write: Debug Mode, Release Mode (used while debuging a project) Trace.write: Release Mode (used in Released verion of Applications) Normal 0 The Debug.Write call won't be compiled when the DEBUG symbol is not defined (when doing a release build). Trace.Write calls will be compiled. Debug.Write is for information you want only in debug builds, Trace.Write is for when you want it in release build as well. Thanks
