如何IsMobileDevice工作？ [英] How does IsMobileDevice work?

问题描述

MSDN 使得它听起来那么容易检测手机浏览器：

MSDN makes it sound so easy to detect a mobile browser:

if (Request.Browser["IsMobileDevice"] == "true" ) 
{
    Response.Redirect("MobileDefault.aspx");
}

其实，它看起来像你也可以只检查Request.Browser.IsMobileDevice。但这是如何实际工作？我甚至不具有一个.browser文件......这是怎么回事这里的幕后？是否有ASP.NET 2.0的一些内置的默认设置？

Actually, it looks like you can also just check Request.Browser.IsMobileDevice. But how does this actually work? I don't even have a .browser file... what's going on behind the scenes here? Are there some built-in defaults for ASP.NET 2.0?

推荐答案

若干* .browser文件是随.NET：

A number of *.browser files are shipped with .NET:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\Browsers

运行时使用常规的前pressions从* .browser文件来匹配输入的用户代理字符串，然后设置了一堆根据每个找到匹配的属性（可以有层次结构中的几个）

The runtime uses regular expressions from the *.browser files to match against the incoming User-Agent string, and then sets a bunch of properties based on each match it finds (there can be several in the hierarchy).

如果你需要深入的移动设备支持，考虑安装MDBF，这增加了支持约400设备：

If you need in-depth mobile device support, consider installing the MDBF, which adds support for about 400 devices:
