一步一步学Silverlight ：与浏览器交互相关辅助方法

HttpUtility方法

类似于WebForm开发中一样，在Silverlight 2中同样提供了一一些HttpUtility方法，共有四个HtmlEncode、HtmlDecode、UrlEncode、UrlDecode，看一个简单的例子：

<Grid x:Name="LayoutRoot" Background="#CDFCAE">
    <Grid.RowDefinitions>
        <RowDefinition Height="75"></RowDefinition>
        <RowDefinition Height="75"></RowDefinition>
        <RowDefinition Height="75"></RowDefinition>
        <RowDefinition Height="75"></RowDefinition>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="400"></ColumnDefinition>
        <ColumnDefinition Width="200"></ColumnDefinition>
    </Grid.ColumnDefinitions>
    
    <TextBox x:Name="txtHtmlEncode" Grid.Row="0" Grid.Column="0" 
             Width="300" Height="40"></TextBox>
    <Button x:Name="btnHtmlEncode" Grid.Row="0" Grid.Column="1" 
            Background="Red" Width="120" Height="40" Content="HtmlEncode"
            Click="btnHtmlEncode_Click"></Button>
    
    <TextBox x:Name="txtHtmlDecode" Grid.Row="1" Grid.Column="0" 
             Width="300" Height="40"></TextBox>
    <Button x:Name="btnHtmlDecode" Grid.Row="1" Grid.Column="1" 
            Background="Red" Width="120" Height="40" Content="HtmlDecode"
            Click="btnHtmlDecode_Click"></Button>
    
    <TextBox x:Name="txtUrlEncode" Grid.Row="2" Grid.Column="0" 
             Width="300" Height="40"></TextBox>
    <Button x:Name="btnUrlEncode" Grid.Row="2" Grid.Column="1" 
            Background="Red" Width="120" Height="40" Content="UrlEncode"
            Click="btnUrlEncode_Click"></Button>
    
    <TextBox x:Name="txtUrlDecode" Grid.Row="3" Grid.Column="0" 
             Width="300" Height="40"></TextBox>
    <Button x:Name="btnUrlDecode" Grid.Row="3" Grid.Column="1" 
            Background="Red" Width="120" Height="40" Content="UrlDecode"
            Click="btnUrlDecode_Click"></Button>
</Grid>

编写按钮处理事件：

private void btnHtmlEncode_Click(object sender, RoutedEventArgs e)
{
    this.txtHtmlDecode.Text = HttpUtility.HtmlEncode(this.txtHtmlEncode.Text);
}

private void btnHtmlDecode_Click(object sender, RoutedEventArgs e)
{
    this.txtHtmlEncode.Text = HttpUtility.HtmlDecode(this.txtUrlDecode.Text);
}

private void btnUrlEncode_Click(object sender, RoutedEventArgs e)
{
    this.txtUrlDecode.Text = HttpUtility.UrlEncode(this.txtUrlEncode.Text);
}

private void btnUrlDecode_Click(object sender, RoutedEventArgs e)
{
    this.txtUrlEncode.Text = HttpUtility.UrlDecode(this.txtUrlDecode.Text);
}

运行后测试如下：
