WPF 委托事件写法

为了代码不看的那么乱，把功能差不多都写到一个方法里，里面用页面分割
首先创建实体类

   public class Studens//数据实体类
        {
            public int id { get; set; }
            public string name { get; set; }
        }
		public delegate void StudensDelegateHandle(Studens studens);
        public static event StudensDelegateHandle StudensDelegateEvent;//事件
        public static void GetStudent(Studens studens)
        {
            if (StudensDelegateEvent != null)
            {
                StudensDelegateEvent(studens);
            }
        }
 		public MainWindow()
        {
            InitializeComponent();
            StudensDelegateEvent = new StudensDelegateHandle(Main_GetStudentEvent);//事件方法
        }
		private void Main_GetStudentEvent(Studens studens)//方法总类
        {
            if (studens == null)
                return;
            try
            {
                switch (studens.id)
                {
                    case 1:
                        {
                            MessageBox.Show("选择了1");
                        }
                        break;
                    case 2:
                        {
                            MessageBox.Show("选择了2");
                        }
                        break;
                }
            }
            catch (Exception e)
            {
                MessageBox.Show(e.Message);
            }
        }
		//测试按钮1
        private void btn1_Click(object sender, RoutedEventArgs e)
        {
            GetStudent(new Studens() { id = 1 ,name="荔枝橙"}) ;
        }
		//测试按钮2
        private void btn2_Click(object sender, RoutedEventArgs e)
        {
            GetStudent(new Studens() { id = 2, name = "张浩" });
        }

在别的页面可以这么用

 Home.GetHomeMessage(new Home.HomeMessage() { Sender = this, Command = "提交", Parameter = record });
