以下是MSDN在“何时使用静态类”一节中所说的:

static class CompanyInfo { public static string GetCompanyName() { return "CompanyName"; } public static string GetCompanyAddress() { return "CompanyAddress"; } //... } Use a static class as a unit of organization for methods not associated with particular objects. Also, a static class can make your implementation simpler and faster because you do not have to create an object in order to call its methods. It is useful to organize the methods inside the class in a meaningful way, such as the methods of the Math class in the System namespace.

对我来说，这个例子似乎没有涵盖静态类的很多可能的使用场景。在过去，我曾将静态类用于相关函数的无状态套件，但仅此而已。那么，在什么情况下应该(和不应该)将类声明为静态的呢?
