asp.net或javascript判断是否手机访问

/// <summary>
/// 判断手机用户UserAgent
/// </summary>
/// <returns></returns>
private bool IsMobile()
{
    
    HttpContext context = HttpContext.Current;
    if (context != null)
    {
        HttpRequest request = context.Request;
        if (request.Browser.IsMobileDevice)
            return true;

        string MobileUserAgent=System.Configuration.ConfigurationManager.AppSettings["MobileUserAgent"];
        Regex MOBILE_REGEX = new Regex(MobileUserAgent);
        if (string.IsNullOrEmpty(request.UserAgent) || MOBILE_REGEX.IsMatch(request.UserAgent.ToLower()))
            return true;            
    }
    return false;
}
 
以下为web.config配置里边的
<add key="MobileUserAgent" value="iphone|android|nokia|zte|huawei|lenovo|samsung|motorola|sonyericsson|lg|philips|gionee|htc|coolpad|symbian|sony|ericsson|mot|cmcc|iemobile|sgh|panasonic|alcatel|cldc|midp|wap|mobile|blackberry|windows ce|mqqbrowser|ucweb"/>

<script>    
var system ={    win : false,    mac : false,    xll : false    };    
//检测平台    
var p = navigator.platform;    
system.win = p.indexOf("Win") == 0;   
system.mac = p.indexOf("Mac") == 0;    
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);    
//跳转语句    
if(system.win||system.mac||system.xll)
{   
    alert(system.mac)    
}
else
{   
    window.location.href="手机访问地址";    
} 
</script>
