C#小伎倆獲取本地或遠程磁盤使用信息

因爲公司有多個服務器，要檢查磁盤的使用情況確定程序放哪個服務器和清理垃圾,所以寫個小程序幫忙檢查。

效果圖:

 

後臺代碼:

 private void btnCheck_Click(object sender, EventArgs e)
        {
            listBox1.Items.Clear();
            if (rbtnRemote.Checked)
            {
                //遠程
                RemoteDisk();
            }
            else
            {
                //本地
                LocalDisk();
            }
        }
        //查看本地
        private void LocalDisk()
        {
            WqlObjectQuery wmiquery = new WqlObjectQuery("select * from Win32_LogiCalDisk");
            ManagementObjectSearcher wmifind = new ManagementObjectSearcher(wmiquery);
            //顯示
            ShowInfo(wmifind);
        }

        //遠程
        private void RemoteDisk()
        {
            if (cbIP.Text == "" | cbUserName.Text == "" | txtPwd.Text == "")
            {
                MessageBox.Show("請把信息補充完整!");
                return;
            }
            string ip = cbIP.Text;
            string username = cbUserName.Text;
            string password = txtPwd.Text;
            ConnectionOptions conn = new ConnectionOptions();
            conn.Username = username;
            conn.Password = password;
            conn.Timeout = new TimeSpan(1,1,1,1);//連接時間

            //ManagementScope 的服務器和命名空間。  
            string path = string.Format(@"\\{0}\root\cimv2", ip);
            //表示管理操作的範圍（命名空間）,使用指定選項初始化ManagementScope 類的、表示指定範圍路徑的新實例。 
            ManagementScope scope = new ManagementScope(path, conn);  
            scope.Connect(); 
            //查詢
            string strQuery = "select * from Win32_LogicalDisk ";
            ObjectQuery query = new ObjectQuery(strQuery);
            //查詢ManagementObjectCollection返回結果集  
            ManagementObjectSearcher wmifind = new ManagementObjectSearcher(scope, query);
