asp.net:如何检测iOS/Android

本文关键字：检测 iOS Android net 何检测 asp | 更新日期: 2023-09-27 17:58:14

我最近推出了一个用C#/.net 4.0编写的web应用程序，广泛使用了jQuery&jQuery UI，以提供尽可能好的用户体验。

然而，一些用户在通过iPhone或Android设备使用该网站时报告了问题。

检测iOS和Android的最佳方法是什么这样我就可以调整每个浏览器的UI了。

一般来说，您应该检测浏览器服务器端，然后将正确的模板/视口渲染到浏览器。检查浏览器发送到服务器的用户代理字符串-iOS通常包含子字符串，"iPhone"和Android使用"Android"，然后是版本号（"Android 2.2"）

我认为最好的解决方案是尝试字符串

Request.ServerVariables["HTTP_USER_AGENT"]

到目前为止，这将为android设备返回android一词。Windows很容易检测。有人帮我拿另一种水果。

这里有一个ASP.NET扩展（显然，我还没有使用它）为您做所有这些：）

IsMobileDevice在我的Android手机上没有给出正确的响应。这是我用过的代码。
