c# – ‘ManagementClass’不存在于命名空间’System.Management’

嗨,我正在使用这个方法获取mac地址

public string GetMACAddress()
{
    System.Management.ManagementClass mc = default(System.Management.ManagementClass);
    ManagementObject mo = default(ManagementObject);
    mc = new ManagementClass("Win32_NetworkAdapterConfiguration");

    ManagementObjectCollection moc = mc.GetInstances();
    foreach (var mo in moc)
    {
        if (mo.Item("IPEnabled") == true)
        {
            return mo.Item("MacAddress").ToString();
        }else
            return null;

    }

}

但我收到这个错误

Compiler Error Message: CS0234: The type or namespace name 'ManagementClass' does not exist in the namespace 'System.Management' (are you missing an assembly reference?)

我要做什么来解决它？

谢谢

解决方法

您需要在项目中使用 add a reference to System.Management.
