Question

How would I refactor this to get it to return a string not a dataset?

[WebMethod] public DataSet GetPONumber(string Database) {     SqlConnection sqlConn = new SqlConnection();      sqlConn.ConnectionString = GetConnString(Database);      // build query     string strSQL = @' A SELECT QUERY!!!!! ';      SqlDataAdapter da = new SqlDataAdapter(strSQL, sqlConn);     DataSet ds = new DataSet();     da.Fill(ds, 'NEWPO');      return (ds); }

This is what I finnished with and is working, thank you for your input:

[WebMethod]     public String GetPONumber(string Database)     {            //Create Object ready for Value         object po = '';          //Set Connection         SqlConnection Connection = new SqlConnection(GetConnString(Database));          //Open Connection         Connection.Open();          //Set Query to string         string Query = @' SQL QUERY GOES HERE!!!! ';          //Run Query         SqlCommand Command = new SqlCommand(Query, Connection);          //Set Value from Query         try         {             po = Command.ExecuteScalar();         }         catch         {             //Error         }          //Clean up sql         Command.Dispose();         Command = null;           //Clean up connection         Connection.Close();         Connection.Dispose();         Connection = null;          //Return Value         return po.ToString();     }
