通过c＃中的设备名称获取蓝牙设备的COM端口

我在C＃中编写了一些代码来获取COM端口，其中映射了具有特定名称的蓝牙设备。 我尝试了几个与此处列出的解决方案类似的解决方案，但是没有一个解决方案我可以访问蓝牙设置窗口中的名称，如下图所示：

如果它在那个窗口，我肯定有办法找到它。 有帮助吗？

非常感谢

Answer 1

请尝试以下代码段。 我用它在我每天使用的应用程序中按名称查找串行设备。

public static bool DoesSerialDeviceExist(string name) { using (var search = new ManagementObjectSearcher ("SELECT * FROM WIN32_SerialPort")) { string[] portnames = SerialPort.GetPortNames(); var ports = search.Get().Cast().ToList(); var tList = (from n in portnames join p in ports on n equals p["DeviceID"].ToString() select n + " - " + p["Caption"]).ToList(); string serial = tList.FirstOrDefault(o => o.Contains(name)); bool isAvailable = false; if (serial != null) { isAvailable = true; } return isAvailable; } }
