c# - MahApps.Metro 消息和进度连接

Question

我想用 MahApps 创建一个如下所示的逻辑:

ShowScreenCommand = new Command(async () =>
{
    var window = Application.Current.MainWindow as MetroWindow;
    if (await window.ShowMessageAsync("Are you sure to remove it?", "Removal", MessageDialogStyle.AffirmativeAndNegative) == MessageDialogResult.Affirmative)
    {
        await removePatientTask();
    }
});

private async Task removeTask()
{
    var window = Application.Current.MainWindow as MetroWindow;
    var controller = await window.ShowProgressAsync("Please wait...","Process message",false,new MetroDialogSettings());

    await Task.Delay(5000);
    await controller.CloseAsync();
}

问题是，消息和进度对话框之间存在间隙。一个对话框隐藏，第二个对话框显示。这看起来并不完美。

有没有办法消除这个差距？我的意思是，用另一个对话框替换一个对话框？

尝试移除 ShowMessageAsync 方法的关闭动画:

await window.ShowMessageAsync("Are you sure to remove it?", 
                              "Removal",
                              MessageDialogStyle.AffirmativeAndNegative,
                              new MetroDialogSettings 
                              { 
                                AnimateHide = false 
                              });

也许您还需要删除 Progress 的显示动画，它基本上是相同的代码，但将 AnimateHide 替换为 AnimateShow。
