如何将参数发送到仅接受 C# 中的一个参数的 webservice 方法

Question

总的来说，我是网络服务的新手。我正在尝试向 rmc 服务 CreateCar 添加 4 个参数，并已尝试在我的 Webservices.cs 文件中这样做。不幸的是，CreateCar 方法只接受 1 个参数（请求）。此代码的大部分基于接受所有参数的类似过程。

我要拨打的电话是 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;
    }

我收到的错误是方法 CreateCar 没有重载需要 4 个参数（这是有道理的）。我只是想说明我想做什么。此方法似乎只需要 1 个参数。

这是参考文件的一个片段，其中包含我发现的相关信息。看来我需要使用参数创建一个 BaseServiceRequest，但我不确定如何创建。

试试这个：

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