反射重要属性方法

  public class Person
  {
      public string Name
      {
          get;
          set;
      }
      public int Age
      {
          get;
          set;
      }
      public string Email
      {
          get;
          set;
      }
      public void SayHi()
      {
          Console.WriteLine("反射的方法调用此方法");
      }
      public void SayHi(string name)
      {
          Console.WriteLine(name+"反射的方法调用此方法");
      }
  }

  public class Student : Person, Iinterface
  {

  }

  public class Teacher : Person, Iinterface
  {

  }


  public interface Iinterface
  {

  }

  public abstract class MyClass1
  {

  }

  public static class MyClass2
  {

  }

  Type typePerson = typeof(Person);
   Type typeStudent = typeof(Student);
   Type typeTeacher = typeof(Teacher);
//智能提示说明，指定的类型实例就是说参数的c
①IsAssignableFrom
 //表示要检查，能否将typeStudent的类型的对象赋值给typePerson的类型
          bool b = typePerson.IsAssignableFrom(typeStudent);
          Console.WriteLine(b);//true

 bool b1 = typePerson.IsAssignableFrom(typeTeacher);
          Console.WriteLine(b1);//true

          bool b2 = typeStudent.IsAssignableFrom(typeTeacher);
          Console.WriteLine(b2);//false;
② IsInstanceOfType，检查某个对象是否是某个类型，是否是它父类
   object objPerson = Activator.CreateInstance(typePerson);
          object objStudent = Activator.CreateInstance(typeStudent);
          object objTeacher = Activator.CreateInstance(typeTeacher);
          ////检查某个对象是否是某个类型的实例。
          Console.WriteLine(typePerson.IsInstanceOfType(objPerson));//true
          Console.WriteLine(typePerson.IsInstanceOfType(objStudent));//true
          Console.WriteLine(typePerson.IsInstanceOfType(objTeacher));//true

          Console.WriteLine(typeTeacher.IsInstanceOfType(objStudent));//false
          Console.ReadKey();
③bool IsSubclassOf(Type c):有2个Type的时候用这个，一个type，一个对象用上面那个；验证父子类，与接口无关

       Console.WriteLine(typePerson.IsSubclassOf(typeStudent));//false
          Console.WriteLine(typePerson.IsSubclassOf(typeTeacher));//false

          Console.WriteLine(typeStudent.IsSubclassOf(typePerson));//true
          Console.WriteLine(typeTeacher.IsSubclassOf(typePerson));//true
          Type typeInterface = typeof(Iinterface);

          //验证是否是父子类关键，和接口无关。
          Console.WriteLine(typeStudent.IsSubclassOf(typeInterface));//false
          Console.WriteLine(typeTeacher.IsSubclassOf(typeInterface));//false
④IsAbstract
  Type typeInterface = typeof(Iinterface);//接口
          Type typeMyClass1 = typeof(MyClass1);//抽象类
          Type typeMyClass2 = typeof(MyClass2); //静态类
          Console.WriteLine(typePerson.IsAbstract);//false
          Console.WriteLine(typeStudent.IsAbstract);//false
          Console.WriteLine(typeTeacher.IsAbstract);//false
          Console.WriteLine(typeInterface.IsAbstract);//true
          Console.WriteLine(typeMyClass1.IsAbstract);//true
          Console.WriteLine(typeMyClass2.IsAbstract);//true
          Console.ReadKey();
