如何在不创建实例的情况下从C＃类调用静态方法

Question

I have code like this:

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"});
        }
    }

In Some.Dll there is public static Method SomeMethod with String param returning String but I get method missing Error...

Answer 1

You are missing the BindingFlags.Static flag.

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
