在 WP 8.1 RT 中以编程方式关闭 MessageDialog [英] Closing MessageDialog programatically in WP 8.1 RT

问题描述

我想关闭并隐藏 Windows Phone 8.1 RT 中的 MessageDialog.我已经通过调用 .Cancel() 和 .Close() 看到了多种解决方案，但没有一个适用于 Windows Phone 8.1 RT；它们仅对 Windows 8 RT 有效.

I want to close and hide the MessageDialog in Windows Phone 8.1 RT. I've seen multiple solutions from calling .Cancel() and .Close(), but none work on Windows Phone 8.1 RT; they're valid only for Windows 8 RT.

如何在不与其交互的情况下从代码中关闭 MessageDialog?

How can I close the MessageDialog from code without interacting with it?

推荐答案

使用 ContentDialog 代替 MessageDialog.ContentDialog 有更多的自定义选项.您可以毫无问题地创建看起来像 MessageDialog 的 ContentDialog，并将其隐藏在代码中.

Use ContentDialog instead MessageDialog. ContentDialog has more customization options. You can create ContentDialog which looks like MessageDialog without any problems, and hide it from code.

示例:

protected override async void OnNavigatedTo(NavigationEventArgs e)
{
    ShowContentDialog("cos");
    await HideContentDialog();
}

ContentDialog _contentDialog;
private void ShowContentDialog(string s)
{
        _contentDialog = new ContentDialog();
    _contentDialog.Content = s;
    _contentDialog.IsPrimaryButtonEnabled = true;
    _contentDialog.PrimaryButtonText = "OK";
    _contentDialog.Title = "title";
    _contentDialog.ShowAsync();
}

private async Task HideContentDialog()
{
    await Task.Delay(5000);
    _contentDialog.Hide();
}
