In this issue, the editor will bring you about the introduction and debugging of C#. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Debugging DotNet programs is one of the necessary skills for DotNet programmers. To develop a stable program and solve the problems of the program requires a strong debugging ability. There are many methods and techniques for DotNet debugging. Now this article will introduce the method of debugging with the help of DebugView tools, as well as the knowledge points derived from DebugView.

DebugView

DebugView is a great tool to view debugging information, support Debug, Release mode compiled procedures, and even support kernel programs, and can customize a variety of filter conditions, so that you can only see the output you care about, and can customize the highlighted content, etc., very convenient.

To capture the debugging information output from a Win32 program in Release mode, you need to select the CaptureGlobalWin32 option:

Filtering and highlighting function

Filter conditions can be set through include and exclude, and the output information containing the specified string will be filtered. You can also filter out the debugging information of the corresponding process ID through the exclude condition. Multiple conditions are separated by ";" and support the "*" wildcard.

Remote debugging

DebugView supports remote capture of debugging information. First start DebugView on the remote machine with the following command:

Several ways of outputting information to DebugView

Do some of the functions of DebugView appeal to you? As the saying goes, action is better than action, but before you act, you need to know how C # outputs debugging information to DebugView.

There are three ways to programmatically output some debugging information to DebugView:

Debug.WriteLine

Debugger.Log

OutputDebugString method in Kernal32.dll

Debug.WriteLine

Debug information can be written to DebugView through Debug.WriteLine

Debugger.Log

Debug.WriteLine is already working well, and the only drawback is that it doesn't work in Release mode. Then you can use the Debugger.Log method in Release mode

OutputDebugString method in Kernel32.dll

C++ developers should know that you can output debugging information to DebugView through the API open implementation of OutputDebugString. So what C++ can do, C # can also do. You can introduce this method through PInvoke, which belongs to Kernel32.dll

You can then output the debugging information to DebugView by calling this method.

This is how the introduction debugging of C# is shared by the editor. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
