Public NotInheritable Class BigcommerceDataReader 
   Inherits Devart.Data.SqlShimDataReader
   Implements System.Collections.IEnumerable, System.Data.IDataReader, System.Data.IDataRecord, System.IDisposable


public sealed class BigcommerceDataReader : Devart.Data.SqlShimDataReader, System.Collections.IEnumerable, System.Data.IDataReader, System.Data.IDataRecord, System.IDisposable

Remarks

To create a BigcommerceDataReader, you must call the ExecuteReader method of the BigcommerceCommand object, rather than directly using a constructor.

System.Data.Common.DbDataReader.IsClosed and RecordsAffected are the only properties that you can call after the BigcommerceDataReader is closed. In some cases, you must call Close before you can call RecordsAffected.

Example

The following example creates a BigcommerceConnection, a BigcommerceCommand, and a BigcommerceDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the BigcommerceDataReader, then the BigcommerceConnection.

        BigcommerceConnection bigcommerceConnection = new BigcommerceConnection(myConnString);
        BigcommerceCommand bigcommerceCommand = (BigcommerceCommand)bigcommerceConnection.CreateCommand();
        bigcommerceCommand.CommandText = "SELECT id, firstname, lastname FROM customers";
        bigcommerceConnection.Open();
        BigcommerceDataReader bigcommerceReader = bigcommerceCommand.ExecuteReader();
        try {
                // Always call Read before accessing data.
                while (bigcommerceReader.Read()) {
                Console.WriteLine(bigcommerceReader.GetInt32(0).ToString() + " " + 
                bigcommerceReader.GetString(1) + " " + bigcommerceReader.GetString(2));

        finally {
                // always call Close when done reading.
                bigcommerceReader.Close();

                // Close the connection when done with it.
                bigcommerceConnection.Close();
        }
}
