WPF - 屏幕顶部的地铁对话框设置(mahapps)?

WPF - Metro Dialog Settings (mahapps) on the top of the screen?

我有一个 WPF 应用程序,我使用 metro dialog 来显示消息。我可以在 window 的顶部显示消息吗?我可以修改 popup 的位置吗?

我找到了一个方法:

try
{
     var mySettings = new MetroDialogSettings
     {
         AffirmativeButtonText = "Yes"
     };

     var cd = new CustomDialog
     {
         VerticalAlignment = VerticalAlignment.Top,
         VerticalContentAlignment = VerticalAlignment.Top
     };

     await DialogManager.ShowMetroDialogAsync(this, cd, mySettings);
}
catch (Exception ex)
{
}
