C#通过 WURFL 获取设备信息

我发现网上WURFL的代码非常少，最近工作时找了好久都找不到，让我来填补一下.NET使用WURFL的空缺吧！

使用语言：C#

环境：.net Framework 4.6.1 (当前使用) MVC4 (貌似支持所有NetWeb环境，我就不多说了)

直接上代码，不多BB：
记得NuGet最新的WURFL，那些我就不写了，都是很简单的

using System;
using System.Configuration;
using System.Diagnostics;
using WURFL;
using WURFL.Aspnet.Extensions.Config;
using System.Web.Caching;
using System.Web;

namespace WURFLandUA
{
    public partial class Index : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            String userAgent = Request.UserAgent;
            var cache = CacheHelper.GetCache("WURFL_XML");//先读取 
            //如果检测到缓存没有则加载：首次加载约3600毫秒：二次加载约0.14毫秒

            if (cache == null)
            {
                WurflSampleASPNETApp.WurflManager = WURFLManagerBuilder.Build(new ApplicationConfigurer());
                CacheHelper.SetCache("WURFL_XML", WurflSampleASPNETApp.WurflManager);
            }
            else
            {
                WurflSampleASPNETApp.WurflManager = cache as IWURFLManager;
            }
            //下面是判断
            IDevice wurflDevice = WurflSampleASPNETApp.WurflManager.GetDeviceForRequest(Request);
            bool
              _android = bool.Parse(wurflDevice.GetVirtualCapability("is_android")) || userAgent.Contains("Android"),
               _iphone = bool.Parse(wurflDevice.GetVirtualCapability("is_ios")) || userAgent.Contains("iPhone")
               ;
            if (_android)
            {
                Response.Redirect(ConfigurationManager.AppSettings["AndroidPage"], false);
            }
            else if (_iphone)
            {
                Response.Redirect(ConfigurationManager.AppSettings["IosPage"], false);
            }
            else
            {
                Response.Write(ConfigurationManager.AppSettings["prompt"]);
            }

        }
    }
    public static class WurflSampleASPNETApp
    {
        public static IWURFLManager WurflManager;
    }
}

因为每次都读取他的XML太慢，所以，我加了缓存处理，为了以防万一，还是加了用户代理判断(UA)
看不懂的可以联系我。私信、qq都行，回复也行，现在是CSDN的常客

之前忘记加上缓存帮助类了，给大家带来不便，现在加上

    public class CacheHelper
    {
        /// <summary>
        ///     获取数据缓存
        /// </summary>
        /// <param name="cacheKey">键</param>
        public static object GetCache(string cacheKey)
        {
            var objCache = HttpRuntime.Cache.Get(cacheKey);
            return objCache;
        }
        /// <summary>
        ///     设置数据缓存
        /// </summary>
        public static void SetCache(string cacheKey, object objObject)
        {
            var objCache = HttpRuntime.Cache;
            objCache.Insert(cacheKey, objObject);
        }

        /// <summary>
        ///     设置数据缓存
        /// </summary>
        public static void SetCache(string cacheKey, object objObject, int timeout = 3600)
        {
            try
            {
                if (objObject == null) return;
                var objCache = HttpRuntime.Cache;
                //相对过期
                //objCache.Insert(cacheKey, objObject, null, DateTime.MaxValue, timeout, CacheItemPriority.NotRemovable, null);
                //绝对过期时间
                objCache.Insert(cacheKey, objObject, null, DateTime.Now.AddSeconds(timeout), TimeSpan.Zero, CacheItemPriority.High, null);
            }
            catch (Exception)
            {
                //throw;
            }
        }
        /// <summary>
        ///     移除指定数据缓存
        /// </summary>
        public static void RemoveAllCache(string cacheKey)
        {
            var cache = HttpRuntime.Cache;
            cache.Remove(cacheKey);
        }
        /// <summary>
        ///     移除全部缓存
        /// </summary>
        public static void RemoveAllCache()
        {
            var cache = HttpRuntime.Cache;
            var cacheEnum = cache.GetEnumerator();
            while (cacheEnum.MoveNext())
            {
                cache.Remove(cacheEnum.Key.ToString());
            }
        }
    }
