II. View msil code in C# using other free tools

 In addition to Visual Studio, which can view msil code, there are also some free viewing tools on the Internet. For example, JustCompiler is a free viewing tool. The capacity of the tool itself is very small, and it can be used after downloading quickly. If Visual Studio is not installed, it is a good choice.
