移动检查方法在某些浏览器上不起作用

Question

我正在使用下面的方法来检查移动版本，但它并不总是适用于所有桌面浏览器，而且这与 IE 版本无关，因为有些机器有 IE9，它保留在我的桌面版本和其他一些带有 IE9 重定向的机器上到移动版本时，我应该总是从 PC 返回 false，并且某些 IE8 用户也发生同样的情况，

此方法有任何例外吗？

        public static bool IsMobile()
        {
            //GETS THE CURRENT USER CONTEXT
            HttpContext context = HttpContext.Current;

            //FIRST TRY BUILT IN ASP.NT CHECK
            if (context.Request.Browser.IsMobileDevice)
            {
                return true;
            }
            //THEN TRY CHECKING FOR THE HTTP_X_WAP_PROFILE HEADER
            if (context.Request.ServerVariables["HTTP_X_WAP_PROFILE"] != null)
            {
                return true;
            }
            //THEN TRY CHECKING THAT HTTP_ACCEPT EXISTS AND CONTAINS WAP
            if (context.Request.ServerVariables["HTTP_ACCEPT"] != null &&
            context.Request.ServerVariables["HTTP_ACCEPT"].ToLower().Contains("wap"))
            {
                return true;
            }
            //AND FINALLY CHECK THE HTTP_USER_AGENT 
            //HEADER VARIABLE FOR ANY ONE OF THE FOLLOWING
            if (context.Request.ServerVariables["HTTP_USER_AGENT"] != null)
            {
                //Create a list of all mobile types
                string[] mobiles = {
"midp", "j2me", "avant", "docomo", 
"novarra", "palmos", "palmsource", 
"240x320", "opwv", "chtml",
"pda", "windows ce", "mmp/",

"moto", "iphone"
};

                //Loop through each item in the list created above 
                //and check if the header contains that text
                foreach (string s in mobiles)
                {
                    if (context.Request.ServerVariables["HTTP_USER_AGENT"].ToLower().Contains(s.ToLower()))
                    {
                        return true;
                    }
                }
            }

            return false;
        }

如果我不需要使用设备功能（通常是 WURFL），那么我会使用此代码。也许您可以使用此正则表达式来完成您的代码。

Answer 2

好的，我找到了解决办法
我添加了更多检查

if (context.Request.UserAgent.ToLower().Contains("pc"))
            {
                return false;
            }
