获取一个对象的属性/属性值,以及动态给属性赋值

 //定义类
    public class MyClass
    {
        public int Property1 { get; set; }
        public string Property2 { get; set; }
    }

 MyClass tmp_Class = new MyClass();
            tmp_Class.Property1 = 2;
            tmp_Class.Property2 = "aq23iu";
            Type type = tmp_Class.GetType(); //获取类型
            System.Reflection.PropertyInfo propertyInfo = type.GetProperty("Property1"); //获取指定名称的属性
            int value_Old = (int)propertyInfo.GetValue(tmp_Class, null); //获取属性值
            Console.WriteLine(value_Old);
            propertyInfo.SetValue(tmp_Class, 5, null); //给对应属性赋值
            int value_New = (int)propertyInfo.GetValue(tmp_Class, null);
            Console.WriteLine(value_New);
