. NET creates its own log class

Internship has been nearly three months, because it is the school-enterprise joint training program, so there is no salary, fortunately, the company for us these interns do not have any requirements, just at the beginning I still feel to do something to learn quickly, but later, found that the company assigned to our task is not urgent, also not too difficult.

Up to now about 2, 3 modules of the design and implementation, at first, in the file read and write and record logs repeatedly received criticism, because the external university time and did not record the habit of day, making this time to develop in the key location of the habit of recording the log has become somewhat difficult,

At first I used Postsharp's third-party plug-in to record my own running logs, but later found that in code porting, if the other computers did not install POSTSHARP, it would complicate the porting process, especially when deploying.

Now that the new module is being used, it is decided not to use Postsharp, and to write a simple logging class to record operations at the critical location.

No nonsense, directly out of the code, the code is relatively simple, the implementation of the function is very simple.

Can be directly copied and pasted to use, at the same time, I also provide the source code for beginners like me to download.
