如何在不创建实例的情况下从C#类调用静态方法

Question

我有这样的代码:

class Program
    {
        static void Main(string[] args)
        {
            Assembly myAsm = Assembly.LoadFile(@"c:\Some.dll");
            Type myService = myAsm.GetType("SomeClass");
            String s = (String) myService.InvokeMember("SomeMethod", BindingFlags.InvokeMethod  | BindingFlags.Public,
    null, null, new object[] {"MyParam"});
        }
    }

在Some.Dll中有公共静态方法SomeMethod与String param返回String但我得到方法缺少错误...

Answer 1

你错过了BindingFlags.Static国旗.

String s = (String) myService.InvokeMember("SomeMethod", BindingFlags.Static | BindingFlags.InvokeMethod  | BindingFlags.Public,
null, null, new object[] {"MyParam"}); 

Answer 2

如果您的方法是静态的,您应该使用此绑定标志:

BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Static
