c# - 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 中有一个 public static Method SomeMethod with String param returning String但是我得到了缺少方法的错误...

您缺少 BindingFlags.Static 标志。

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