本文主要：如何让WebView访问的网页设别为手机，当然这句话我说不好，换个，如何让WebView设别为手机。上面两句话都是错的，因为是服务器识别，不是网页，第二句话应该是让服务器而不是WebView。为什么这样写是因为有大神在群里问这个，他这样说，我这样写希望大家能在搜索看到。当然本文发在csdn和win10.me，在他地方并没有发，不过我的gitbook.io还是有的。

如何让WebView设别手机，其实很简单，但是我开始没有找到WebView userAgent 其实发现他不需要。

我们在前台

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <WebView x:Name="Webview"/>
        <Button Content="手机" Click="WebPhone_OnClick"/>
    </Grid>

然后在后台很简单

因为我们需要使用httpRequestMessage，他可以有httpRequestMessage.Headers.Add("User-Agent", userAgent);那么我们发现Webview.NavigateWithHttpRequestMessage

我把这些写按钮

        private void WebPhone_OnClick(object sender, RoutedEventArgs e)
        {
            var httpRequestMessage = new Windows.Web.Http.HttpRequestMessage(Windows.Web.Http.HttpMethod.Get, new Uri(Url));
            var userAgent = "Mozilla/5.0 (Windows Phone 10.0; Android 4.2.1; WebView/3.0; Microsoft; Virtual) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Mobile Safari/537.36 Edge/12.10240 sample/1.0";
            httpRequestMessage.Headers.Add("User-Agent", userAgent);
            Webview.NavigateWithHttpRequestMessage(httpRequestMessage);
        }

这里

 var userAgent = "Mozilla/5.0 (Windows Phone 10.0; Android 4.2.1; WebView/3.0; Microsoft; Virtual) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Mobile Safari/537.36 Edge/12.10240 sample/1.0";

可以修改

    public sealed partial class MainPage : Page

            this.InitializeComponent();
            Webview.Navigate(new Uri(Url));
        }
        private string Url { set; get; }
        = "http://blog.csdn.net/lindexi_gd";

        private void WebPhone_OnClick(object sender, RoutedEventArgs e)
        {
            var httpRequestMessage = new Windows.Web.Http.HttpRequestMessage(Windows.Web.Http.HttpMethod.Get, new Uri(Url));
            var userAgent = "Mozilla/5.0 (Windows Phone 10.0; Android 4.2.1; WebView/3.0; Microsoft; Virtual) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Mobile Safari/537.36 Edge/12.10240 sample/1.0";
            httpRequestMessage.Headers.Add("User-Agent", userAgent);
            Webview.NavigateWithHttpRequestMessage(httpRequestMessage);
        }
    }
}
