我们在开发wap应用程序需要有识别来访手机品牌型号的功能，这样才可以更好的为用户提供更好的个性化服务，比如图片类型、屏幕尺寸、铃声类型等。

      http协议中，User-Agent这个标头指示的浏览器信息,文章最后附加了常见的手机User-Agent.

      每个厂家，甚至一个厂家多个品牌的User-Agent都没有一个统一命名标准，所以处理起来相当麻烦---不停的if。

比如判断某个手机的品牌

        If Request.UserAgent.ToUpper.StartsWith("MOT") Or Request.UserAgent.ToUpper.StartsWith("MOT") Then
            '摩托罗拉
        End If
        If Me.Request.UserAgent.ToUpper.IndexOf("-SGH") > 0 Then
            '三星
        End If

判断型号的话方法同上。

 这样处理也有一些例外，比如摩托罗拉E360 会识别成T33这个是厂商的问题了。。

常见手机User-Agent：
