以下是移动的设备检测代码,包含三种不同的情况

if (Request.Browser.IsMobileDevice)
{
   //Do Something
}
else if (((System.Web.Configuration.HttpCapabilitiesBase)myBrowserCaps).IsMobileDevice)
{
  //Do Something
}
else if (IsMobileDevice(mobileDevices))
{
  //Do Something
}

public bool IsMobileDevice()
{
     private static string[] mobileDevices = new string[] {"iphone","ppc"
                                                   "windows ce","blackberry",
                                                   "opera mini","mobile","palm"
                                                   "portable","opera mobi" };

         string userAgent = Request.UserAgent.ToString().ToLower();
         return mobileDevices.Any(x => userAgent.Contains(x));
 }

我被迫写了三个条件,因为它们对一些设备失败。
谁能提出一个更好的方法?

将代码从:http://detectmobilebrowsers.com/

    public static bool fBrowserIsMobile()
    {
        Debug.Assert(HttpContext.Current != null);

        if (HttpContext.Current.Request != null && HttpContext.Current.Request.ServerVariables["HTTP_USER_AGENT"] != null)
        {
            var u = HttpContext.Current.Request.ServerVariables["HTTP_USER_AGENT"].ToString();

            if (u.Length < 4)
                return false;

            if (MobileCheck.IsMatch(u) || MobileVersionCheck.IsMatch(u.Substring(0, 4)))
                return true;
        }

        return false;
    }
}

这就是你的说法

if (Utils.fBrowserIsMobile())
{
    // go to mobile pages
}

我对代码http://detectmobilebrowsers.com/所做的更改

  • 静态编译Regex以加快检查速度。
  • 修正u小于4个字符的错误。
  • 其他检查。

使用缓存

这段代码很快,其中一个诀窍是我们将regex设置为静态并预编译。我建议在第一次检查后将结果保存在用户会话中,并使用该会话变量,这样会快得多。

这段代码在我的案例中有效。

public void IsMobileBrowser()
{
    String labelText = "";
    System.Web.HttpBrowserCapabilities myBrowserCaps = Request.Browser;
    if (((System.Web.Configuration.HttpCapabilitiesBase)myBrowserCaps).IsMobileDevice)
    {
        labelText = "Browser is a mobile device.";
    }
    else
    {
        labelText = "Browser is not a mobile device.";
    }
    ScriptManager.RegisterStartupScript(this, this.GetType(), "", "alert('"+ labelText + "');", true);
}

参考:HttpCapabilitiesBase.IsMobileDevice Property

我使用DeviceDetector.NET,因为我经常还需要将智能手机和平板电脑分开
安装Install-Package DeviceDetector.NET
那就这样用吧

DeviceDetectorSettings.RegexesDirectory = "C:\\DeviceDetector.NET.3.11.4\\";
var dd = new DeviceDetector(Request.UserAgent);
dd.Parse();

var device = dd.GetDeviceName();

if(device == "tablet") {}
if(device == "smartphone") {}
if(device == "desktop") {}

/**
Possible returns
--
desktop
smartphone
tablet
feature phone
console
tv
car browser
smart display
camera
portable media player
phablet
**/

正则表达式可以在packages目录中找到

Scott Hanselman在这个问题上有一个很棒的blog post。他提到了一个名为51Degrees的第3方解决方案。

u5i3ibmn5#

现有的浏览器定义很糟糕。理想情况下,您希望使用WURFL database来扩充这些定义。
幸运的是,使用51 Degrees.mobi library很容易做到这一点。
还有一个Nuget package

Install-Package 51Degrees.mobi

我建议将用户代理列表存储在web.config中,以使其更容易配置。IsMobileDevice不会主动更新新的浏览器,因此它确实有它的限制,这就是为什么你需要进一步检查。
51Degrees.mobi包将是一个更可靠的替代方案。

检查代码隐藏中的UserAgent是否有“Mobi”,类似于javascript引用的here

if (Request.UserAgent.Contains("Mobi") == true)
                {
                    DivToShowWhenMobileDevice.Style.Add("display", "");
                }
                else
                {
                    DivToShowWhenMobileDevice.Style.Add("display", "none");
                }

当然,如果你想确定用户代理可能是最好的方法。你也可以看看这个方法:
http://msdn.microsoft.com/en-us/library/system.web.configuration.httpcapabilitiesbase.ismobiledevice.aspx
它应该有一些新的浏览器等问题。但它是这一个,因为你目前所做的。
