我需要使用C#查询网络适配器的Hardware-Id。
使用System.Management我可以查询deviceID,描述等的详细信息,但不能查询硬件ID。
其中,listBox1是一个简单的列表框控件实例,用于显示winform应用程序中的项目。
例如:
ManagementObjectCollection mbsList = null;
ManagementObjectSearcher mbs = new ManagementObjectSearcher("Select * From Win32_NetworkAdapter");
mbsList = mbs.Get();
foreach (ManagementObject mo in mbsList)
{
listBox1.Items.Add("Name : " + mo["Name"].ToString());
listBox1.Items.Add("DeviceID : " + mo["DeviceID"].ToString());
listBox1.Items.Add("Description : " + mo["Description"].ToString());
}
然而,查看MSDN WMI参考,我无法获得HardwareId。 通过使用devcon工具( devcon hwids = net )但我知道每个设备都与HardwareId相关联
非常感谢任何帮助

您正在寻找的HardwareID位于另一个WMI类中。获得Win32_NetworkAdapeter的实例后,可以使用PNPDeviceId选择Win32_PnpEntry。下面是一个示例代码,列出了所有网络适配器及其硬件ID(如果有):
ManagementObjectSearcher adapterSearch = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_NetworkAdapter");
foreach (ManagementObject networkAdapter in adapterSearch.Get())
{
string pnpDeviceId = (string)networkAdapter["PNPDeviceID"];
Console.WriteLine("Description : {0}", networkAdapter["Description"]);
Console.WriteLine(" PNPDeviceID : {0}", pnpDeviceId);
if (string.IsNullOrEmpty(pnpDeviceId))
continue;
// make sure you escape the device string
string txt = "SELECT * FROM win32_PNPEntity where DeviceID='" + pnpDeviceId.Replace("\\", "\\\\") + "'";
ManagementObjectSearcher deviceSearch = new ManagementObjectSearcher("root\\CIMV2", txt);
foreach (ManagementObject device in deviceSearch.Get())
{
string[] hardwareIds = (string[])device["HardWareID"];
if ((hardwareIds != null) && (hardwareIds.Length > 0))
{
Console.WriteLine(" HardWareID: {0}", hardwareIds[0]);
}
}
}
