Ding Ding's Reflector tool can refract programs written in C #, VB.NET, and Delphi. This tool has been coming out, and Lutz Roeder has been upgrading this tool. The current version is Version 4.1.25.0. Use this tool to try to open a program written by C #, after the anti-compilation, the C # code is almost a little uncomfortable. It seems that there is not much secret to the program written in .Net. For those in the learning stage, it should be said to be a good thing.
There are still some bugs, such as sometimes it is time to do, and so on. But for such a free tool, it is really quite good.
There are several other .NET anti-compilation tools, but they have not been used. do not know if its good or not.
