Webservice having trouble pass back to client - asp.net

Question

I having trouble passing back the result which is multiple row getting from MS-SQL2012 to client. I have tried to google up but still not find the solution. Since I'm new in .NET and this is my first webservice, required an assistant to solve my problem or suggest any better solution.
Result need to pass back to client
Public Class Service1
Inherits System.Web.Services.WebService
Public Class Dealer
Public IDNo, ICFound, POFound As String
End Class
<WebMethod()> _
Public Function DailyCheckDealer(records As String()()) As String
Dim mylist As List(Of String()) = records.ToList()
Dim datarow As String = ""
Dim result As String = "Done"
For i As Integer = 0 To mylist.Count - 1
Dim m As String() = mylist(i)
For j As Integer = 0 To m.Length - 1
datarow += m(j) + " "
Next
Next
//Insert the array into the database.
Dim objDealer As New Dealer
Dim myConnString = System.Configuration.ConfigurationManager.AppSettings("MM_CONNECTION_STRING_iPRIS")
Dim myConnection1 = New SqlConnection(myConnString)
Dim myCommand = New SqlCommand()
myCommand.CommandType = CommandType.StoredProcedure
myCommand.Connection = myConnection1
myCommand.CommandText = "DailyCheckDealer"
myCommand.Parameters.Add("#DataRow", SqlDbType.VarChar, 8000).Value = datarow
myConnection1.Open()
myCommand.ExecuteNonQuery()
myConnection1.Close()
// Get the record(s) after processing and return it back to client
Dim myConnection2 = New SqlConnection(myConnString)
Dim objComm As New SqlCommand("Select IDNo, IDFound, POFound From DailyDealerCheck Order By IDNo", myConnection2)
myConnection2.Open()
Dim sdr As SqlDataReader = objComm.ExecuteReader()
If sdr.Read() Then
objDealer.IDNo = sdr("IDNo").ToString()
objDealer.ICFound = sdr("IDFound").ToString()
objDealer.POFound = sdr("POFound").ToString()
End If
myConnection2.Close()
Return objDealer
End Function
End Class

Answer 1

You're getting your data and putting it into objDealer which is an instance of type Dealer. You then actually have Return objDealer
Clrearly you want to return an instance of Dealer. However your function is declared as returning a string. That shouldn't even compile! Change the declaration to this:
<WebMethod()> _
Public Function DailyCheckDealer(records As String()()) As Dealer
That will allow it to return a Dealer not a string.
EDIT - to return more than one Dealer:
<WebMethod()> _
Public Function DailyCheckDealer(records As String()()) As List(Of Dealer)
' code left out
Dim myConnection2 = New SqlConnection(myConnString)
Dim objComm As New SqlCommand("Select IDNo, IDFound, POFound From DailyDealerCheck Order By IDNo", myConnection2)
' Create list of Dealers for return
Dim dealerList as New List(Of Dealer)
myConnection2.Open()
Dim sdr As SqlDataReader = objComm.ExecuteReader()
If sdr.Read() Then
objDealer.IDNo = sdr("IDNo").ToString()
objDealer.ICFound = sdr("IDFound").ToString()
objDealer.POFound = sdr("POFound").ToString()
' Add the latest to the list
dealerList.Add(objDealer)
End If
myConnection2.Close()
' Return list of dealers
Return dealerList
End Function
