C # reflection get private functions

Assembly assembly = Assembly.LoadFrom(@"..\..\..\Common\bin\Debug\Common.dll");Type t = assembly.GetType("Common.ForPrivate");MethodInfo method = t.GetMethod("Find", BindingFlags.NonPublic | BindingFlags.Instance);object obj = Activator.CreateInstance(t);obj result = method.Invoke(obj, new object[] { });

Assembly = assembly. loadfrom (@ "... \ .. \ common \ bin \ debug \ common. dll ");

Type T = assembly. GetType ("..");

In these two ways, the DLL of the referenced class is not obtained. Of course, it can also be an .exe file. Here, the number of .. \ is the number of parent directories pushed up in the current directory.

Naturally, if you add a reference to the target class in the current project, you can directly use type
T = typeof (forprivate );

Type T = assembly. GetType ("common. forprivate ");

This line, the string in the function, must be prefixed with a namespace.

Methodinfo method = T. getmethod ("find", bindingflags. nonpublic | bindingflags. instance );

The nonpublic and instance flags must be added at the same time. Otherwise, the corresponding private function will not be available.

Object OBJ = activator. createinstance (t );

You can also use this sentence instead:

Object OBJ = assembly. createinstance ("common. forprivate ");

Finally, Object Re = method. Invoke (OBJ, null)

If the called function has a return value, you must have an object type to accept it. Otherwise, an exception occurs.
