How to reference a web service user defined type?

Hi,

I'm having some difficulty trying to ref. a user defined type in K2 Studio. 

 
In my webservice I have these user defined classes:
 

public class ADMember
{
    public string username;
    public string firstname;
    public string lastname;
    public string employeeNumber;
}

public class ADMemberArr
{
    public ADMember[] admemberArr;
}

My webservice has the ADMemberArr returning back:

public ADMemberArr GetMembers(string LDAPFilter)    {

       ...
        return oADMemberArr;      
    }

In K2 Studio I have this in my code:

public void Main(ref DestinationRuleContext K2) {
   
    K2.ResolveQueuesToUsers = true;
   
    SourceCode.K2Utilities.DSHelper oDSH = new SourceCode.K2Utilities.DSHelper(SourceCode.K2Utilities.DSHelper.DSHelperNewOptionsEnum.DefaultLDAPDomain);
    System.DirectoryServices.DirectoryEntry oDEManager;
    string sManager;
    bool bAllTrue = true;
    CDest1 oDest1 = new CDest1();
    oDest1.Main(ref K2);
   
   
    ADService.ADService oADSvc = new ADService.ADService();
    ADService.ADMemberArr oADMemberArr = new ADService.ADMemberArr();
   
    ADService oWebService = new ADService();   
       
    try
    {   
        oWebService.Url = "http://teknck2stage/common/ADService.asmx";
        oWebService.Credentials = SourceCode.K2Utilities.GeneralMod.GetCredentials(oWebService.Url);
        object oADMemberArr = oWebService.GetMembers("tekDepartmentNumber=8031)");
                   
        foreach(ADService.ADMember oADMember in oADMemberArr.admemberArr())
        {
            if (oDest1.IsSuccess == true) {
            //== sendto
                K2.Destinations.Add(DestinationType.User, oADMember.username);
           
                if (bAllTrue == false) return;
            }       
        }
       

    }
    catch (Exception ex)
    {
        throw ex;
    }
    finally
    {
        oWebService = null;
    }   

}

// Destination Classes
   
private class CDest1 {
    public bool IsSuccess = false;
       
    public void Main(ref DestinationRuleContext K2) {
        this.IsSuccess = true;
    }

}

 However it does not compile nicely in K2 Studio... I get these errors saying it doesn't recognize the types.

 Line 13: The type name 'ADMemberArr' does not exist in the type 'ADService'
 Line 21: The type name 'ADMember' does not exist in the type 'ADService' 

I think I'm referencing this wrong unlike in Visual Studio.  Any idea how I can do this?

Thanks,

Vinny
