How to get a Windows Phone 7's useragent string?
I need to get a phone's user agent string, but I haven't found anything in the API that allows this. I've come across the following two blog posts describing the format of the user agent string:

But I haven't found a method that can return the user a开发者_StackOverflowgent. Has anyone been able to do this successfully?
Go to http://whatsmyuseragent.com using the phone in question.
From my Samsung Focus: Mozilla/4.0 (compatible: MSIE 7.0; Windows Phone OS 7.0; Trident/3.1; IEMobile/7.0; SAMSUNG; SGH-i917)
I made this helper that will create a temporary WebBrowser, load a script and return an awaitable userAgent:
internal static class UserAgentHelper
{
private const string Html = @"<!DOCTYPE html><html><body onload=""window.external.notify(navigator.userAgent);""></body></html>";
public static Task<string> GetUserAgent()
{
var tcs = new TaskCompletionSource<string>();
var browser = new WebBrowser { IsScriptEnabled = true };
browser.ScriptNotify += (sender, args) => tcs.SetResult(args.Value);
browser.NavigateToString(Html);
return tcs.Task;
}
}
Usage:
var userAgent = await UserAgentHelper.GetUserAgent();
It works at least for WP7.1 and WP8.0:
WP7: "Mozilla/5.0 (compatible; MSIE 9.0; Windows Phone OS 7.5; Trident/5.0; IEMobile/9.0; Microsoft; XDeviceEmulator)";
WP8: "Mozilla/5.0 (compatible; MSIE 10.0; Windows Phone 8.0; Trident/6.0; IEMobile/10.0; ARM; Touch; Microsoft; Virtual)";
加载中,请稍侯......
