Perhaps the best angle is Reflector, take a look-see at the System.Data.dll assembly. It is in an unnamed namespace ("-" in Reflector), <Module> node. The .cctor you see there is a module initiailizer. Same kind of animal as a static class constructor but at the module level. It runs when the assembly gets loaded. C++/CLI uses it to initialize the C runtime library.

在___ CxxCallUnwindDtor（）方法，你会发现有一个全球方法的一个例子。在C ++ / CLI语言并没有给任何办法，使这几样功能公众，他们总是嵌入在内部访问的元数据。并因此不能直接从C＃或VB.NET程序中调用。我还没有发挥足够的与ModuleBuilder知道是否可以与被搞砸都超出了C ++ / CLI一样。这是所有的非常的模糊不清，实际上并没有那么有用。

The ___CxxCallUnwindDtor() method you find there is an example of a "global method". The C++/CLI language doesn't give any way to make these kind of functions public, they are always embedded in the metadata with internal accessibility. And can thus not be called directly from a C# or VB.NET program. I haven't played enough with ModuleBuilder to know if that can be messed with at all beyond what C++/CLI does. This is all very obscure and not actually that useful.
