计算机加入域C#程序

之前一直用vbs脚本加域，最近有需求要用c#做一个加入域的客户端，找到两种加域的方法，都可以实现计算机加入域功能。

1、调用WMI对象加域；

 public static int SetDomainMembership(string DomainName, string UserName, string Password,out string err)

        {
            err = "System Error!";
            // Invoke WMI to join the domain
            using (ManagementObject wmiObject = new ManagementObject(new ManagementPath("Win32_ComputerSystem.Name='" + System.Environment.MachineName + "'")))
            {
                try
                {
                    // Obtain in-parameters for the method
                    ManagementBaseObject inParams = wmiObject.GetMethodParameters("JoinDomainOrWorkgroup");
                   

                    inParams["Name"] = DomainName;                    
                    inParams["Password"] = Password;
                    inParams["UserName"] = UserName + "@" + DomainName;
                    inParams["AccountOU"] = null;
                    inParams["FJoinOptions"] = 3; //
                    // Execute the method and obtain the return values.
                    ManagementBaseObject outParams = wmiObject.InvokeMethod("JoinDomainOrWorkgroup", inParams, null);
                    
                    switch (outParams["ReturnValue"].ToString())
                    {
                        case "5":
                            err = "Access is denied";
                            break;
                        case "87":
                            err = "The parameter is incorrect";
                            break;
                        case "110":
                            err = "The system cannot open the specified object";
                            break;
                        case "1323":
                            err = "Unable to update the password";
                            break;
                        case "1326":
                            err = "Logon failure: unknown username or bad password";
                            break;
                        case "1355":
                            err = "The specified domain either does not exist or could not be contacted";
                            break;
                        case "2224":
                            err = "The account already exists";
                            break;
                        case "2691":
                            err = "The machine is already joined to the domain";
                            break;
                        case "2692":
                            err = "The machine is not currently joined to a domain";
                            break;                                                   
                    }
                    return Convert.ToInt32(outParams["ReturnValue"]);                 
                }
                catch (ManagementException e)
                {
                    // It didn't work                    
                    return -1;
                }
            }
        }

2、调用NetDom对象加域； 

 public static int SetDomainMembership2(string DomainName, string UserName, string Password, out string err)

        {
            err = string.Empty;
            try
            {
                string DomainNameHost = DomainName;
                uint value1 = NetJoinDomain(null, DomainNameHost, null, UserName+"@"+DomainName, Password, (JoinOptions.NETSETUP_JOIN_DOMAIN | JoinOptions.NETSETUP_DOMAIN_JOIN_IF_JOINED | JoinOptions.NETSETUP_ACCT_CREATE));
                err = value1.ToString();
                return Convert.ToInt32(value1) ;
            }
            catch (Exception e)
            {
                err = e.ToString();
                return -1;
            }
        }

        [DllImport("netapi32.dll", CharSet = CharSet.Unicode)]
        static extern uint NetJoinDomain(
          string lpServer,
          string lpDomain,
          string lpAccountOU,
          string lpAccount,
          string lpPassword,
          JoinOptions NameType);

        [Flags]
        enum JoinOptions
        {
            NETSETUP_JOIN_DOMAIN = 0x00000001,
            NETSETUP_ACCT_CREATE = 0x00000002,
            NETSETUP_ACCT_DELETE = 0x00000004,
            NETSETUP_WIN9X_UPGRADE = 0x00000010,
            NETSETUP_DOMAIN_JOIN_IF_JOINED = 0x00000020,
            NETSETUP_JOIN_UNSECURE = 0x00000040,
            NETSETUP_MACHINE_PWD_PASSED = 0x00000080,
            NETSETUP_DEFER_SPN_SET = 0x10000000
        }
