Mahapps中如何获取ShowInputAsync Dialog的结果

Question

ShowInputAsync() returns 一个字符串，但我想从对话框中得到结果，我的意思是确认或取消。

Answer 1

如果是returnsnull，表示用户点击了取消:

    private async void Button_Click(object sender, RoutedEventArgs e)
    {
        var result = await this.ShowInputAsync("Test", "Enter string:");

        if (result == null)
            return;

        await this.ShowMessageAsync("Test", "You entered " + result + "!");
    }
