cs1501 error

Bob Alston 121

I get cs1501 error - No overload for method 'download' takes 7 arguments.

Running this code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web.Services.Description;

namespace ConsoleApp7
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var service = new us.tx.state.dshs.cmbhs.DataDownloadService { Url = "http:s://cmbhs.dshs.state.tx.us/cmbhswebservice/Service/DataDownloadService.asmx?wsdl" };
            var mydata = service.Download("xxIDxxx", "yyPWyyy", "449737", "2022-10-01", "2022-10-03","12","02");
            Console.WriteLine(mydata);

Error on  line "var mydata = ..."

I read internet posts which don't really tell me how to fix this.
Thanks for assistance

Hi Bob Alston,

Is Download a custom method of yours? I suggest you check that it has so many parameters when it is defined.

About CS1501 I suggest you refer to this document.

Yes there are 7 parameters required. Two are the UserID and Password and 5 others that set the request.

I am following the instructions in this web posting:

https://stackoverflow.com/questions/38058579/how-to-create-soap-xml-client-from-wsdl-in-console-cron-job-app-c-sharp-vs2012

When I use the SoapUI utility against the WSDL I get a form that looks like this:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:cmb="http://www.dshs.state.tx.us/cmbhs/">
   <soap:Header>
      <cmb:CMBHSAuthenticationHeader>
         <!--Optional:-->
         <cmb:CMBHSUserName>xxxxxxxxxx</cmb:CMBHSUserName>
         <!--Optional:-->
         <cmb:CMBHSPassword>yyyyyyyyyy</cmb:CMBHSPassword>
      </cmb:CMBHSAuthenticationHeader>
   </soap:Header>
   <soap:Body>
      <cmb:Download>
         <cmb:organizationNbr>449737</cmb:organizationNbr>
         <cmb:fromDate>2022-10-01</cmb:fromDate>
         <cmb:toDate>2022-10-03</cmb:toDate>
         <cmb:downloadType>12</cmb:downloadType>
         <cmb:downloadDateType>02</cmb:downloadDateType>
      </cmb:Download>
   </soap:Body>
</soap:Envelope>

The "download" method is defined in the WSDL.

I am guessing that the problem is in how I am setting the 7 parameters for the method.

OK. The revised code below gives me a workable non-soap connection, but there is no way to enter the userID and Password.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web.Services.Description;

namespace ConsoleApp7
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var service = new us.tx.state.dshs.cmbhs.DataDownloadService();

            DateTime FromDate = new DateTime(2022, 10, 01);
            DateTime   ToDate = new DateTime(2022, 10, 03);
            var mydata = service.Download(449737,FromDate ,ToDate , 12, 02);
            Console.WriteLine(mydata);
        }
    }
}

Again I am using this process:
https://stackoverflow.com/questions/38058579/how-to-create-soap-xml-client-from-wsdl-in-console-cron-job-app-c-sharp-vs2012

It does connect to the web service and returns error about the missing userid and password.

I could not see the soap service when I used the WSDL on the web.  But in the example, if you use a local WSDL it shows soap services.  I will try doing it that way.

Any other ideas?
Bob

Hi Bob Alston,

Could you check the definition of Download? I suggest you check the number and types of parameters of the method and whether it is overloaded.

If it is convenient, could you please tell me how to get us.tx.state.dshs.cmbhs.DataDownloadService()?Currently I cannot test this code.

I am trying to use Visual Studio 2022 to generate the classes and code to submit the soap.xml request.

I am trying to use VS2022 and this wsdl to connect to a service that indeed has 7 params. Two are in the authentication header which is in fact required and 5 normal parameters.

Since I have the fundamental code with the 5 parameters sent, perhaps all I need now is to know how to send the authentication info - ID and PW - as part of the request. See the wsdl for information on the authentication info required.

Hi Bob Alston,

I checked the definition of Download(), it has only five parameters, I think you may need to customize a function that suits your needs.
