c#擷取本機電腦相關資訊

建立一個類.然後讀取資訊.調用代碼如下.
HardInfoClass myclass=new HardInfoClass();
   textBox1.Text=myclass.GetHardDiskID();
   textBox2.Text=myclass.GetCpuID();
   textBox3.Text=myclass.GetNetCardMAC();
   textBox4.Text=myclass.GetNetCardIP();
   textBox5.Text=myclass.GetHostName();
   textBox6.Text=myclass.GetVolOf("D");//C盤58c6b679跟D盤6ed62864不一樣

   //textBox7.Text=myclass.GetHashCode();
   //textBox8.Text=myclass.GetCpuID();  

類HardInfoClass代碼如下
