The internship has been nearly three months now. Due to the school-enterprise joint training plan, there is no salary. Fortunately, the company has no requirements for our interns, at the beginning, I felt that I had to do something to learn quickly. However, after that, I found that the tasks assigned to us by the company were not very important and difficult.

Now we have been engaged in the design and implementation of around two or three modules. At first, we were repeatedly criticized for reading, writing, and logging files, because we didn't have the habit of recording days at external universities, this makes it difficult to quickly develop the habit of logging in key locations,

At first, I used a third-party postsharp plug-in to record my running logs. However, it was later published in code porting. If postsharp is not installed on other computers, the porting process will become complicated, in particular, it increases complexity during deployment.

Now, when implementing the new module, I decided not to use postsharp any more. I planned to write a simple log record class to record operations in key locations.

 

The code is simple and the implementation function is very simple.

You can directly copy and paste it for use. At the same time, I also provide the source code for beginners like me to download.
