I can't figure it out for the life of me.. I'm using SQL DataSet Query to iterate to a Class Object which acts as a Data Model for Flex... Initially I used VB.net but now need to convert to C#.. This conversion is done except for the last section where I create a DataRow arow and then try to add the DataSet Values to the Class (Results Class)... I get an error message..

'VTResults.Results.Ticker' is inaccessible due to its protection level (this is down at the bottom)

 [WebService(Namespace = "http://velocitytrading.net/ResultsVT.aspx")]
 [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
 public class VTResults : System.Web.Services.WebService {
     public class Results {
         string Ticker;
         string BuyDate;
         decimal Buy;
         string SellDate;
         decimal Sell;
         string Profit;
         decimal Period;
     }
     [WebMethod]
     public Results[] GetResults() {
         string conn =                
 ConfigurationManager.ConnectionStrings["LocalSqlServer"].ConnectionString;
    SqlConnection myconn = new SqlConnection(conn);
    SqlCommand mycomm = new SqlCommand();
    SqlDataAdapter myda = new SqlDataAdapter();
    DataSet myds = new DataSet();

    mycomm.CommandType = CommandType.StoredProcedure;
    mycomm.Connection = myconn;
    mycomm.CommandText = "dbo.Results";

    myconn.Open();
    myda.SelectCommand = mycomm;
    myda.Fill(myds);
    myconn.Close();
    myconn.Dispose();

    int i = 0;

    Results[] dts = new Results[myds.Tables[0].Rows.Count];
    foreach(DataRow arow in myds.Tables[0].Rows)
    {
        dts[i] = new Results();
        dts[i].Ticker = arow["Ticker"];
        dts[i].BuyDate = arow["BuyDate"];
        dts[1].Buy = arow["Buy"];
        dts[i].SellDate = arow["SellDate"];
        dts[i].Sell = arow["Sell"];
        dts[i].Profit = arow["Profit"];
        dts[i].Period = arow["Period"];
        i+=1;
    }
    return dts;
     }    
   }

The VB.NET WEBSERVICE that runs fine which I am trying to convert to C# is here.
