題目： find the key
提示： debug net
1. Open kington.exe. You would see the rock, paper, scissors game and you never win.
2. Use PEiD, and find source code is written by C#
3. Reverse it by .net decompiler (Like Telerik JustDecompile) and use Visual Studio edit it
I found button5 and textBox2 were hidden, but nothing happen after clicking it.
4. So I changed to see the button1~3 click function, it would call the selectbutton function. SEE SOMETHING??
5. Remove the code and run it again.
6. You will see the key!!!
