asp.net 通过UserAgent判断智能设备(Android,IOS)

最近一直在升级公司的手机站点，出了个触屏版专用的，做好后，就尝试通过 agent 来判断相应的智能手机设备，然后跳转到新的手机站点经过不懈的努力，终于搜集了比较全的 智能设备 的 agent，然后又写了程序，直接上代码吧 ，希望能帮助到你

/// <summary>
/// 根据 agent 判断是否是智能手机
/// </summary>
/// <returns></returns>
public static bool checkagent()
{
bool flag = false;
string agent = httpcontext.current.request.useragent;
string[] keywords = { "android", "iphone", "ipod", "ipad", "windows phone", "mqqbrowser" };
//排除window 桌面系统 和 苹果桌面系统
if (!agent.contains("windows nt") && !agent.contains("macintosh"))
{
foreach (string item in keywords)
{
if (agent.contains(item))
{
flag = true;
break;
}
}
}
return flag;
}

代码解释：

1. !agent.contains("windows nt") && !agent.contains("macintosh") 排除window 桌面系统 和 苹果桌面系统

2. "android", "iphone", "ipod", "ipad", "windows phone", "mqqbrowser" 这些是判断智能设备agent中的关键词

3. mqqbrowser 为 qq 手机浏览器，qq 手机的agent 比较特殊，所以单独判断


下面搜集的一些agent，话说找到这么多的智能设备，好不容易啊：
