关于dotnet,不能在一般的控制台应用程序console中的静态main函数中使用带返回值的函数,因为这是还没有生成对象.

如

public static void Main(){string strtemp = GetNetCardMacAddress();System.Console.WriteLine(strtemp);}

而应该编写类

using System.Management;namespace myDomain{class CTest{private ManagementClass mc;private ManagementObjectCollection moc;private ManagementObject disk;/// <summary>/// 取得设备网卡的MAC地址/// </summary>public string GetNetCardMacAddress(){mc = new ManagementClass("Win32_NetworkAdapterConfiguration");moc = mc.GetInstances();string str = "";foreach(ManagementObject mo in moc){if((bool)mo["IPEnabled"] == true)str = mo["MacAddress"].ToString();}return str;}/// <summary>/// 取得设备硬盘的卷标号/// </summary>/// <returns></returns>public string GetDiskVolumeSerialNumber(){disk = new ManagementObject("win32_logicaldisk.deviceid=\"c:\"");disk.Get();return disk.GetPropertyValue("VolumeSerialNumber").ToString();}}}

然后

public static void Main(){CTest run = new CTest();System.Console.WriteLine("您的硬盘的卷标号" + run.GetDiskVolumeSerialNumber());System.Console.WriteLine("您的网卡的" + run.GetNetCardMacAddress());}
