If I create a static class in C#, will any methods inside be considered static as well, regardless of whether they're explicitly declared as static?

I am getting an interesting error, in that when I call a method (which I don't explicitly declare as static) from within a statically declared class, I get a message saying

An object reference is required for the non-static field, method, or property 'MangoTree.Twitter.OAuthClient.PerformRequest(System.Collections.Generic.Dictionary, string, string, string, MangoTree.Twitter.OAuthClient.RequestType)'

当我将该方法显式声明为静态时，错误就会消失，并且我可以从类声明中删除 static 修饰符，错误就会消失。让我感到困惑的是，我的印象是，当我将类声明为静态时，类中的所有内容都应该自动是静态的，而无需我显式声明它。

静态类的所有成员确实必须是静态的，但这不会自动发生：您必须显式声明所有成员都是静态的。将类声明为静态的目的是让编译器检查所​​有成员是否都是静态的，并防止任何创建静态类实例的尝试。
