问题描述

I know that there is no way to get OS version in Windows Store app, please let me explain more.

My app is a Windows Store app programming with C#. Some features of my app is depend on another desktop app (maybe it's not a good design). As I know, a third-party desktop app can not install on Windows RT, so I just want to know if my app is running on Windows RT and forbid some features of my app on Windows RT. I don't want to use GetNativeSystemInfo(), because it's a win32 API, and if I use that API, my app can't compli with any cpu.

解决方案

Yep. Here's how!

Task<ProcessorArchitecture> WhatProcessor()
{
    var t = new TaskCompletionSource<ProcessorArchitecture>();
    var w = new WebView();
    w.AllowedScriptNotifyUris = WebView.AnyScriptNotifyUri;
    w.NavigateToString("<html />");
    NotifyEventHandler h = null;
    h = (s, e) =>
    {
        // http://blogs.msdn.com/b/ie/archive/2012/07/12/ie10-user-agent-string-update.aspx
        // IE10 on Windows RT: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; ARM; Trident/6.0;)
        // 32-bit IE10 on 64-bit Windows: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)
        // 64-bit IE10 on 64-bit Windows: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Win64; x64; Trident/6.0)
        // 32-bit IE10 on 32-bit Windows: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0) 
        try
        {
            if (e.Value.Contains("ARM;"))
                t.SetResult(Windows.System.ProcessorArchitecture.Arm);
            else if (e.Value.Contains("WOW64;") || e.Value.Contains("Win64;") || e.Value.Contains("x64;"))
                t.SetResult(Windows.System.ProcessorArchitecture.X64);
            else
                t.SetResult(Windows.System.ProcessorArchitecture.X86);
        }
        catch (Exception ex) { t.SetException(ex); }
        finally { /* release */ w.ScriptNotify -= h; }
    };
    w.ScriptNotify += h;
    w.InvokeScript("execScript", new[] { "window.external.notify(navigator.userAgent); " });
    return t.Task;
}

Best of luck!
