C#读取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#编写,.NET Framework 3.5),目前在完整的Windows 7平板电脑上运行,该平板电脑内置了一个用于数据连接的3G模块。数据连接在Windows中配置为普通移动宽带连接(因此Windows管理连接本身),并且连接显示在控制面板中>网络和互联网>网络连接,它工作正常 - 该应用程序能够通过互联网与我们的网络服务进行通信。我们将在未来某个时候转移到另一台设备(可能是基于Windows 8的完整平板电脑)。

现在,我需要做的是阅读此移动宽带连接的连接状态;即获得信号强度和运营商名称(例如Vodafone UK)。我找到了一种方法,使用Windows 7 SDK的移动宽带API部分(请参阅herehere),但这似乎是特定于操作系统,因为它在Windows上不起作用8 - 或者至少不是我在这里的设备。

是否有使用.NET框架读取移动宽带连接属性的通用方法?

或者,是否有人知道Windows 8 SDK包含移动宽带API,如我目前正在使用的Windows 7?

提前致谢。

更新 - 我现在已经开发了一系列不同的Win 7 / Win 8设备。即使是联想设备也能正常工作。我将发布主要位的示例代码(读取连接状态,配置连接,检查SIM状态)作为答案;这个代码有点太长了,无法解决这个问题。

以编程方式配置连接(您将需要APN详细信息):
