MahApp MessageDialog隱藏

Question

我用兩個線程，人會問，在WPFMahApps MessageDialog用戶問題，

另一個我想隱藏MessageDialog，如何隱藏MessageDialog在下面的代碼HideMessageDialog()？

我正在做一些事情，需要中斷問題，並保持主窗口同時打開。所以我需要一種方法來隱藏對話框真正顯示後的對話框。

public void Execute() 
    { 
     Task showAsk = new Task(ShowAskingDialog); 
     Task hideAsk = new Task(HideAskingByCode); 

     showAsk.Start(); 
     hideAsk.Start(); 
    } 

    public async void ShowAskingDialog() 
    { 
     Thread.Sleep(3000); 

     this.MetroDialogOptions.ColorScheme = MetroDialogColorScheme.Accented; 
     var msgbox_settings = new MetroDialogSettings { 
     AffirmativeButtonText = "I know", NegativeButtonText = "I don't know" }; 

     // puase at asking MessaageDialog 
     var isKnow = await this.ShowMessageAsync(
        "Question", "Do you know WPF?", 
        MessageDialogStyle.AffirmativeAndNegative, msgbox_settings); 

    } 

    public void HideAskingByCode() 
    { 
     Thread.Sleep(5000); 

     //How to Hide the MessageDialog by code, not by user click Button? 
     HideMessageDialog(); 
    } 

的MessageDialog會顯示這樣的，鑲嵌在主窗口：

感謝@Nobody和the answer，

隱藏MessageDialog可以使用一般HideMetroDialogAsync()：

public void HideMessageDialog() 
{  
    this.Dispatcher.Invoke(
     async() =>{ 

      BaseMetroDialog dialogBeingShow = 
       await this.GetCurrentDialogAsync<BaseMetroDialog>(); 

      //Hide Current Single Dialog 
      if(dialogBeingShow != null) 
       await this.HideMetroDialogAsync(dialogBeingShow); 

      //Or Hide All Dialogs 
      while (dialogBeingShow != null) 
      { 
       await this.HideMetroDialogAsync(dialogBeingShow); 
       dialogBeingShow = 
        await this.GetCurrentDialogAsync<BaseMetroDialog>(); 
      } 

       } 
      ); 
}
