How to read an ADOQueryConnection with C# in Infopath 2013

Question

I am currently creating my first InfoPath Form with C# code on the back end. It is connecting to a SQL Server DB as well. When the form opens I want it to connect to our SQL Server DB and pull in the user's name and title automatically. However, I'm rather stuck on what seems like a very simple task.

How do I read the data from an ADO Connection after I've executed the query? Below is my code. This seems so simple but I can't seem to figure it out.

AD_Mirror contains the ADO Connection to the DB and the appropriate table. The CustomQuery is my attempt to filter this down by the user that is opening the form.

I then execute it in theory grabbing the user information I need. Then I am unsure as to how to proceed. I've searched all over for an answer, so any help would be greatly appreciated.

       //ADO Attempt
        AdoQueryConnection connection =
       (AdoQueryConnection)DataConnections["AD_Mirror"];

        string customQuery = " where SamAccountName = '" + userName + "'";
        string origCommand = connection.Command.ToString();
        //set the query to use the custom command
        connection.Command = origCommand + customQuery;
        //annnnnnddddd, now we run the query using our shiny new command           
         connection.Execute();

So I had to separate out the connection from the SQL Query. Then pull in a datatable to pull the data in.

    string queryString = origCommand + customQuery;  //Pull in Query
    string conn = connection.Connection;  //Grab Connection

                     using (OleDbConnection connection1 = new OleDbConnection(conn))
             {
                 OleDbCommand command = new OleDbCommand(queryString, connection1);
                 command.CommandType = CommandType.Text;

                 try
                 {
                     connection1.Open();
                     OleDbDataAdapter adapter = new OleDbDataAdapter(command);
                     adapter.Fill(oSet);

                             string firstName = (oSet.Tables[0].Rows[0].ItemArray[9]).ToString();
                     firstName = firstName.Trim();

My query has First Name in Column 9 (hence the above ItemArray of 9). You can set it tup to loop through this if you need to but I didn't.

Thanks
