我正在编写我的第一个 Windows Phone 教程。我已经下载了 sdk 和更新。我正在按照下面的教程进行操作。

教程

当我编译并单击调试时，模拟器启动并且 UI 正确显示。问题是当我点击“开始”按钮时，什么也没有发生。该应用程序应显示上面文本框中的 url。

有谁知道为什么，对不起，如果很明显，但我今天已经开始从android背景学习这个。

Partial Public Class MainPage
    Inherits PhoneApplicationPage

    ' Constructor
    Public Sub New()
        InitializeComponent()
    End Sub

    Private Sub url_TextChanged(sender As System.Object, e As System.Windows.Controls.TextChangedEventArgs) Handles url.TextChanged

    End Sub

    Private Sub Go_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)

        Dim site As String

        site = URL.Text

        MiniBrowser.Navigate(New Uri(site, UriKind.Absolute))

    End Sub
End Class

.

哦，非常基本的错误:(

您忘记为 Button 分配 Click 事件处理程序

<Button x:Name="Go" Content="Go" Click="Go_Click" VerticalAlignment="Top" HorizontalAlignment="Right"/>

尽管我有带有 GO 按钮的事件，但我没有看到任何事情发生，下面是代码

XAML

        <Button x:Name="Go" Content="Go" HorizontalAlignment="Right" Margin="346,10,0,0" VerticalAlignment="Top" Click="Go_Click"/>

CS

私人无效Go_Click（对象发送者，RoutedEventArgs e）

    {
        //string site = URL.Text;
        //MiniBrowser.Navigate(new Uri(site, UriKind.Absolute));
        string site = URL.Text;
        if (String.IsNullOrEmpty(site)) return;
        if (!site.StartsWith("http://") && !site.StartsWith("https://"))
            site = "http://" + site;
        MiniBrowser.Navigate(new Uri(site, UriKind.RelativeOrAbsolute));
    }
