C# async + metro mahapp 진행 반지

Question

GUI가 정지하기 때문에 응용 프로그램과 비동기에 진행률 링이 필요합니다. 다른 설정 async/wait/task/task.run을 시도했지만 GUI가 여전히 고정되어 있고 링이 나타나지 않고 Main과 CS에 WaitRing.IsActive가 있습니다. 예, 핑은 빠르지 만 주소 IP가 오프라인이면 GUI가 4-5 초 동안 고정되어 있습니다. 메서드가 MainForm에있을 때 async/await를 적용하는 것이 더 쉽습니다. Class에서이 작업을 수행하는 데 문제가 있으며 mahapp의 메시지 상자가 필요할 때가 있습니다.

XAML :

<Controls:ProgressRing x:Name="WaitRing" IsActive="False" Foreground="{DynamicResource AccentColorBrush}" /> 

CS :

공용 클래스 DrukarkaPing { 공공 텍스트 상자의 TextBox_Drukarki_IP {얻을; 세트; }

public async Task CheckPing(TextBox TextBox_Drukarki_IP) 
{ 

    try 
    { 
     if (TextBox_Drukarki_IP.Text == "" || TextBox_Drukarki_IP.Text == " ") 
     { 
      return; 
     } 
     else 
     { 
      Ping PingZapytanie = new Ping(); 
      PingReply PingOdp = PingZapytanie.Send(TextBox_Drukarki_IP.Text); 

      if (PingOdp.Status == IPStatus.Success) 
      { 
       TextBox_Drukarki_IP.Background = new SolidColorBrush(Colors.Green); 
      } 
      else 
      { 
      TextBox_Drukarki_IP.Background = new SolidColorBrush(Colors.Red); 
      } 
     }

     if (window != null) 
      await window.ShowMessageAsync("Błąd!", e.Message); 
     return; 
    }

실행중인 코드는 작업에 압축되어 있지 않으므로 비동기로 실행되지 않습니다. PING을 백그라운드에서 실행하려면 CheckPing Method가 다음과 같아야합니다.

public async Task CheckPing(TextBox TextBox_Drukarki_IP) 
{ 
    try 
    { 
     var text = TextBox_Drukarki_IP.Text; // get TextBox.Text in UI thread 

     if (!string.IsNullOrWhiteSpace(text)) 
     { 
      //Now the Ping.Send is running in Background 
      PingReply PingOdp = await Task.Run(() => 
      { 
       Ping PingZapytanie = new Ping(); 
       return PingZapytanie.Send(text); 
      }); 

      //This code is running on the UI Thread again (because you access a FrameworkElement) 
      if (PingOdp.Status == IPStatus.Success) 
      { 
       TextBox_Drukarki_IP.Background = new SolidColorBrush(Colors.Green); 
      } 
      else 
      { 
       TextBox_Drukarki_IP.Background = new SolidColorBrush(Colors.Red); 
      } 
     } 
    } 
    catch (Exception e) 
    { 
     var window = Application.Current.Windows.OfType<MetroWindow>().FirstOrDefault(); 
     if (window != null) 
      await window.ShowMessageAsync("Błąd!", e.Message); 
     return; 
    } 
}
