C#读取Windows宽带连接属性

Question

首先，这里是背景：

我们有一个Windows应用程序(用C#编写，.NET Framework3.5编写)，目前运行在Windows 7平板电脑上，其中内置了一个用于数据连接的3G模块。数据连接在Windows中配置为正常的移动宽带连接(因此Windows管理连接本身)，连接显示在“控制面板”>“网络”和“Internet >网络连接”中，并且工作良好--应用程序能够通过internet与我们的web服务进行通信。在未来的某个时候，我们将转向另一种设备(可能是一款完整的基于Windows 8的平板电脑)。

现在，我需要做的是读取这个移动宽带连接的连接状态，即获取信号强度和载波名称(例如，沃达丰英国)。我已经找到了一种使用Windows7SDK的Mobile部分(请参阅here和here)来实现这一点的方法，但是这似乎是特定于操作系统的，因为它在Windows 8上不起作用--或者至少对我这里的设备不起作用。

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，有人知道Windows8SDK包含一个移动宽带API，就像我目前正在使用的Windows 7那样吗？

提前谢谢。

更新-我已经在一系列不同的Win 7/ Win 8设备上工作。就连联想的设备也能正常工作。我将把主位的示例代码(读取连接状态、配置连接、检查SIM状态)作为答案；代码太长了，无法回答这个问题。

以编程方式配置连接(您将需要APN详细信息)：

try

            MbnInterfaceManager mbnInfMgr = new MbnInterfaceManager(); 
            IMbnInterfaceManager mbnInfMgrInterface = mbnInfMgr as IMbnInterfaceManager;
            if (mbnInfMgrInterface != null)
            {
                IMbnInterface[] mobileInterfaces = mbnInfMgrInterface.GetInterfaces() as IMbnInterface[];
                if (mobileInterfaces != null && mobileInterfaces.Length > 0)
                {
                    // Just use the first interface
                    IMbnSubscriberInformation subInfo = mobileInterfaces[0].GetSubscriberInformation();

                    if (subInfo != null)
                    {
