新建一个类库，编写如上这个需要反射获取信息的类，然后编译生成一个dll文件，将这个dll文件添加到主程序中，那么主程序如何调用呢？
主程序生成
1static void Main(string[] args)
2 {
3 Console.WriteLine("Hello World!");

5 var assembly = Assembly.LoadFrom(@"ReflectedInfo.dll");

12 Console.WriteLine("==========================");
13
14 var instance = Activator.CreateInstance(type);

16
17 // PS 此处注意 BindingFlags.Instance 或者 BindingFlags.Static 不填默认是找不到除公有外的其余修饰类型的字段的
