C # core code of game plug-ins

Recently, a friend introduced me to start playing classified online games.
After upgrading, I suddenly felt that the keyboard was too expensive, so I wrote Program In place of my operations, I want to beat monsters and upgrade myself.
I have used this item for many upgrades. Now I am posting the source code and sharing it with you. Thank you for your criticism and correction.
The program is divided into two parts: a class library and an application
The general idea is to find the main window handle of the game process, and then send the game button message (analog button ).
