C#阅读Windows Mobile宽带连接属性

首先,这是背景:

我们有一个Windows Forms应用程序(用C#,.NET Framework 3.5编写),当前运行在完整的Windows 7平板电脑上,内置了一个用于数据连接的3G模块。 数据连接在Windows中configuration为正常的移动宽带连接(所以Windows本身就是pipe理连接),连接显示在控制面板>networking和Internet>networking连接中,并且工作正常 – 应用程序能够通过互联网与我们的networking服务。 我们将在未来的某个时间转移到其他设备(可能是完整的基于Windows 8的平板电脑)。

现在,我需要做的是读取移动宽带连接的连接状态。 即获得信号强度,以及运营商名称(如沃达丰英国)。 我已经find了使用Windows 7 SDK的移动宽带API部分的方法(请参阅此处和此处 ),但是这似乎是操作系统特定的,因为它在Windows 8上不起作用 – 或者至less不是设备,我在这里。

有没有一种通用的方式来阅读使用.NET框架的移动宽带连接属性?

另外,有没有人知道Windows 8 SDK,其中包含我正在使用的Windows 7移动宽带API?

提前致谢。

更新 – 我现在已经在一系列不同的Win 7 / Win 8设备上工作了。 即使联想设备工作正常。 我将发布主要位的示例代码(读取连接状态,configuration连接,检查SIM卡状态)作为答案; 令人烦恼的是,代码有点太长了。

移动宽带API也可在Windows 8桌面上使用。

如果您使用Windows 8 Metro / RT /任何名称,则需要这些WindowsRT API (Windows.Connectivity.NetworkInformation等)。

以编程方式配置连接 (您将需要APN详细信息):
