C#读取Windows Mobile Broadband连接属性
本文关键字：连接 属性 Broadband Mobile 读取 Windows | 更新日期: 2023-09-27 18:29:59
首先，这里是背景：
我们有一个Windows窗体应用程序（用C#编写，.NET Framework 3.5），目前正在完整的Windows 7平板电脑上运行，该平板电脑内置了用于数据连接的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自己管理连接），连接显示在"控制面板">"网络和Internet">"Network Connections"中，工作正常-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；即获得信号强度和运营商名称（例如Vodafone UK）。我已经找到了一种使用Windows 7 SDK中的移动宽带API部分来实现这一点的方法（请参阅此处和此处），但这似乎是特定于操作系统的，因为它在Windows 8上不起作用，或者至少不与我这里的设备一起使用。
有没有一种通用的方法可以使用.NET框架读取移动宽带连接属性？
或者，有人知道一个Windows 8 SDK，它包含一个移动宽带API，就像我目前使用的Windows 7一样？
提前谢谢。
更新-我现在已经在一系列不同的Win7/Win8设备上完成了这项工作。即使联想设备也工作正常。我会张贴主要位的示例代码（读取连接状态、配置连接、检查SIM卡状态）作为答案；令人恼火的是，代码有点太长了，不适合讨论这个问题。

移动宽带API也可在Windows 8桌面中使用。
如果您使用的是Windows 8 Metro/RT/任何名称，您都需要这些WindowsRT API（Windows.Connectivity.NetworkInformation等）。
