如何将参数发送到仅接受C＃中的一个参数的Web服务方法

Question

I am new to webservices in general. I am trying to add 4 parameters to the rmc service CreateCar, and have attempted to do so in my Webservices.cs file. Unfortunately, the CreateCar method only takes 1 argument (request). Most of this code is based on similar processes that do accept all the parameters.

The call I am trying to make is the rmcService.CreateCar.

    public bool CreateCar(string url, string viewedUserType, string userName, string accounts, string carName)
    {
        bool returnValue = false;

        try
        {
            if (accounts.Length != 9)
            {
                if (accounts.Length == 8)
                {
                    accounts = accounts + "0";
                }
                else
                {
                    throw new ApplicationException("Invalid length for Account #");
                }
            }

            // Initialize web service object
            relationshipmgmtcentersvcdev.RmcService rmcService = new relationshipmgmtcentersvcdev.RmcService();
            rmcService.Url = url;

            // Attach credentials
            rmcService.Credentials = _Credentials;

            // Connection pooling
            rmcService.ConnectionGroupName = _Credentials.UserName.ToString();
            rmcService.UnsafeAuthenticatedConnectionSharing = true;

            // Hard coding View User Type as None
            viewedUserType = "None";

            // Call to create CAR - Client Account Relation
            rmcService.CreateCar(userName, viewedUserType, accounts, carName); 
            returnValue = true;
        }
        catch (Exception ex)
        {
            System.Diagnostics.EventLog eventLog = new System.Diagnostics.EventLog("Application");
            eventLog.Source = "UAccCompWrapper";
            eventLog.WriteEntry("Error in CreateCar Method: " + ex.ToString(), System.Diagnostics.EventLogEntryType.Error);
        }

        return returnValue;
    }

The error I receive is no overload for method CreateCar takes 4 arguments (which makes sense). I was just trying to illustrate what I was trying to do. This method only takes 1 argument it seems.

This is a snippet of the reference file with the information I found was relevant. It appears that I need to create a BaseServiceRequest with the parameters, but I am unsure how.

Try this:

rmcService.CreateCar(new CreateCarServiceRequest
                    {
                        UserName = userName,
                        ViewedUserType = Enum.Parse(typeof(ViewedUserType), viewedUserType)
                        Accounts = accounts,
                        CarName = carName
                    });
