因为公司有多个服务器，要检查磁盘的使用情况确定程序放哪个服务器和清理垃圾,所以写个小程序帮忙检查。
private void btnCheck_Click(object sender, EventArgs e)
        {
            listBox1.Items.Clear();
            if (rbtnRemote.Checked)
            {
                //远程
                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);
            //显示
            ShowInfo(wmifind);
        }

        //远程
        private void RemoteDisk()
        {
            if (cbIP.Text == "" | cbUserName.Text == "" | txtPwd.Text == "")
            {
                MessageBox.Show("请把信息补充完整!");
                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);//连接时间

            //ManagementScope 的服务器和命名空间。  
            string path = string.Format(@"\\{0}\root\cimv2", ip);
            //表示管理操作的范围（命名空间）,使用指定选项初始化ManagementScope 类的、表示指定范围路径的新实例。 
            ManagementScope scope = new ManagementScope(path, conn);  
            scope.Connect(); 
            //查询
            string strQuery = "select * from Win32_LogicalDisk ";
            ObjectQuery query = new ObjectQuery(strQuery);
            //查询ManagementObjectCollection返回结果集  
            ManagementObjectSearcher wmifind = new ManagementObjectSearcher(scope, query);
            ShowInfo(wmifind);
        }

        #region 显示磁盘信息

            string type = "";
            string str = "";
            double freePath = 0d;
            foreach (var mobj in wmifind.Get())
            {

                    freePath = Math.Round(Convert.ToDouble(mobj["FreeSpace"]) / gb, 1);
                    str += " 可用空间:" + freePath+ "G";
                    str += " 实际大小:" + Math.Round(Convert.ToDouble(mobj["Size"].ToString()) / gb, 1) + "G";
                    if (freePath < 20)

                    }

试试其它关键字
同语言下
可能有用的
