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) =>
{

// 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)

// 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!
