BlogEngine2.0里找到的：

Web.Config:

 

<appSettings>    <!-- 这是一个正则表达式，用来标识移动设备。被识别出的移动设备将采用移动版的主题模板 -->    <add key="BlogEngine.MobileDevices" value="http://www.mamicode.com/(iemobile|iphone|ipod|android|nokia|sonyericsson|blackberry|samsung|sec/-|windows ce|motorola|mot/-|up.b|midp/-)"/>  </appSettings>

/// <summary>///     Gets a value indicating whether the client is a mobile device./// </summary>/// <value><c>true</c> if this instance is mobile; otherwise, <c>false</c>.</value>public static bool IsMobile{    get    {        var context = HttpContext.Current;        if (context != null)        {            var request = context.Request;            if (request.Browser.IsMobileDevice)            {                return true;            }            if (!string.IsNullOrEmpty(request.UserAgent) && RegexMobile.IsMatch(request.UserAgent))            {                return true;            }        }        return false;    }}
