检测 wlan 是否关闭 [英] detect if wlan is turned off

问题描述

谁能给我一个提示，如果启用/禁用 WLAN，如何在 Windows Phone 8.1. 应用程序(不是 8.0！)上以编程方式检测 C#?我不想更改这些设置，只需要知道...

can anybody give me a hint, how to programmatically detect in C# on Windows Phone 8.1. App (not 8.0!), if the WLAN is enabled / disabled? I don't want to change these settings, just need to know...

解决方案是 Windows 8.1 通用应用程序，(Windows Phone 8.1)项目只是引用.Net for Windows Store Apps 和 Windows Phone 8.1.按照建议添加 C:Program Files (x86)Reference AssembliesMicrosoftFrameworkWindowsPhonev8.1Microsoft.Phone.dll 并查询 IsWiFiEnabled 属性不起作用- 编译器错误:在 mscorlib.dll 中找不到 System.SystemException 类型

The Solution is a Windows 8.1 universal app, and the (Windows Phone 8.1) project just references .Net for Windows Store Apps and Windows Phone 8.1. Adding the C:Program Files (x86)Reference AssembliesMicrosoftFrameworkWindowsPhonev8.1Microsoft.Phone.dll as suggested and querying the IsWiFiEnabled property does not work - Compiler error: Cannot find type System.SystemException in mscorlib.dll

谢谢，马赫

推荐答案

如果您正在寻找非 8.1 Silverlight 解决方案:

If you're looking for a Non 8.1 Silverlight solution:

您可以使用 Windows.Networking.Connectivity 命名空间来查询.

You can use the Windows.Networking.Connectivity namespace to query this.

MSDN 网络信息类

一个让你入门的例子

bool is_wifi_enabled = false;
Guid adapter_id = new Guid();

// get the list of connection profiles
// we need the adpater id for the wifi
foreach (var item in NetworkInformation.GetConnectionProfiles())
{

    // check if wifi
    if (item.IsWlanConnectionProfile)
    {
        // tag the adapter
        adapter_id = item.NetworkAdapter.NetworkAdapterId;
    }
}

// get all lan adapters (this most likely will be empty if wlan is disabled)
foreach (var item in NetworkInformation.GetLanIdentifiers())
{
    if (item.NetworkAdapterId == adapter_id)
    {
        is_wifi_enabled = true;
    }
}
