我在拉伸我的图像以填充按钮时遇到问题,我是UWP的新手,这是我的代码:

 <Grid  Margin="0,0,0,54" VerticalAlignment="Bottom" Height="39" Style="{Binding HorizontalAlignment, ElementName=grid}" ScrollViewer.HorizontalScrollBarVisibility="Auto">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>

        <Button Grid.Column="0"  Height="39" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
            <Image Source="images/icon1.png" Stretch="Fill" RenderTransformOrigin="0.5,0.5" UseLayoutRounding="True" d:LayoutRounding="Auto" />

        </Button>
        <Button Grid.Column="1"  Height="39" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
            <Image Source="images/icon2.png" Stretch="Fill" RenderTransformOrigin="0.5,0.5" UseLayoutRounding="True" d:LayoutRounding="Auto" />
        </Button>

</Grid>

我正在使用Windows应用商店,我正在尝试发送登录名和密码值,这是我的代码:

 try
        {
            string user = login.Text;
            string pass = password.Password;

            ASCIIEncoding encoding = new ASCIIEncoding();
            string postData = "login=" + user + "&mdp=" + pass;
            byte[] data = encoding.GetBytes(postData);

            WebRequest request = WebRequest.Create("myURL/login.php");
            request.Method = "POST";

            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data.Length;

            Stream stream = request.GetRequestStream();
            stream.Write(data, 0, data.Length);
            stream.Dispose();

            WebResponse response = request.GetResponse();
            stream = response.GetResponseStream();

            StreamReader sr = new StreamReader(stream);


            sr.Dispose();
            stream.Dispose();


        }
        catch (Exception ex)
        {
            ex.Message.ToString();
        }

我有很多这样的错误:

'WebRequest' does not contain a definition for …

我试图在通用应用程序中将Text设置为RichTextBlock,这是我在xaml中的代码:

<RichTextBlock x:Name="descr">
       <Paragraph>
             <Paragraph.Inlines>
                 <Run Text="{Binding Path=desc}"/>
             </Paragraph.Inlines>
       </Paragraph>
</RichTextBlock>

但我不知道如何在代码背后的RichTextBlock中设置Text,这是我的尝试:

Paragraph p = new Paragraph();
  p.Inlines.Add("test");//error here cannot convert from 'string' to 'Windows.UI.Xaml.Documents.Inline' 
  descr.Blocks.Add(p);

那么如何在C#后面的代码中将Text设置为RichTextBlock,感谢您的帮助

我创建了一个ContentDialog套用样式(我不能用一个消息对话框,然后弹出的应用),但我有它的问题,它是不可移动的或我不能关闭它像出现的框,当我单击Groove应用程序中的"Connexion"按钮

请你有任何想法,我可以在ContentDialog样式中修改哪一部分,以使这个ContentDialog可以移动并关闭它像顶部的图像
