首先，我们需要在网络上下载一个Coding4Fun

然后，引用  using Coding4Fun.Phone.Controls.Toolkit;

                using Coding4Fun.Phone.Controls;

//第一种:AboutPrompt：说明弹出框，特点是弹出框会在屏幕中间，其他的弹出框是在屏幕的上方。private void About_Click(object sender, RoutedEventArgs e){    var about = new AboutPrompt();    about.Completed += baseObject_Completed;    about.Show("是一款精品手机阅读应用，用户可免费下载和使用。它是一个可随身携带的的电子书店，海量图书可供用户免费下载，向用户提供轻松舒适的阅读体验。随时随地，畅享阅读。");}           void baseObject_Completed(object sender, PopUpEventArgs
     
       e) {      if (e.PopUpResult == PopUpResult.Ok)       MessageBox.Show("OK!");      else if (e.PopUpResult == PopUpResult.Cancelled)       MessageBox.Show("CANCELLED!");      else MessageBox.Show("meh?"); }
     

//第二种:ToastPrompt：类似于土司推送通知一样的显示效果，在屏幕上面出现一条消息，然后再消失。public string ToastLongMsg = "123";private void Toast_Click(object sender, RoutedEventArgs e) {     var toast = new ToastPrompt     {          Title = "Basic",          Message = ToastLongMsg,      };      toast.Show(); }

//第三种：PasswordInputPrompt：密码输入弹出框，用于输入密码信息。private void Password_Click(object sender, RoutedEventArgs e) {      var passwordInput = new PasswordInputPrompt      {           Title = "Basic Input",           Message = "I'm a basic input prompt",       };       passwordInput.Completed += new   EventHandler
     
      
       >(passwordInput_Completed);      passwordInput.Show(); }void passwordInput_Completed(object sender, PopUpEventArgs
       
         e) {       if (e.PopUpResult == PopUpResult.Ok)        MessageBox.Show("You typed: " + e.Result);       else if (e.PopUpResult == PopUpResult.Cancelled)        MessageBox.Show("CANCELLED! " + e.Result);       else MessageBox.Show("meh?  " + e.Result); }
       
      
     

private void Input_Click(object sender, RoutedEventArgs e) {     var input = new InputPrompt      {          Title = "Basic Input",          Message = "I'm a basic input prompt",      };      input.Completed += input_Completed;      input.Show(); }           void input_Completed(object sender, PopUpEventArgs
     
       e) {      if (e.PopUpResult == PopUpResult.Ok)       MessageBox.Show("You typed: " + e.Result);      else if (e.PopUpResult == PopUpResult.Cancelled)       MessageBox.Show("CANCELLED! " + e.Result);      else MessageBox.Show("meh?  " + e.Result); }
     

//第五种：MessagePrompt：消息弹出框，普通的消息弹出框，类似于系统默认的messagebox弹出框。private void Message_Click(object sender, RoutedEventArgs e) {      var messagePrompt = new MessagePrompt       {            Title = "Basic Message",             Message = "I'm a basic message prompt.  ",             //ActionPopUpButtons       };        messagePrompt.Completed += stringObject_Completed;       messagePrompt.Show(); }           void stringObject_Completed(object sender, PopUpEventArgs
     
       e) {      if (e.PopUpResult == PopUpResult.Ok)       MessageBox.Show("OK: " + e.Result);      else if (e.PopUpResult == PopUpResult.Cancelled)       MessageBox.Show("CANCELLED: " + e.Result);      else MessageBox.Show("meh?: " + e.Result); }
