BigcommerceDataReader Class
Reads a forward-only stream of rows from BigCommerce.
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.
public void ReadMyData(string myConnString) {
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();
}
}
Public Sub ReadMyData(ByVal myConnString As String)

While bigcommerceReader.Read()
Console.WriteLine(String.Concat(bigcommerceReader.GetInt32(0).ToString(), " ", _
bigcommerceReader.GetString(1), " ", bigcommerceReader.GetString(2)))
End While
Finally
' always call Close when done reading.
bigcommerceReader.Close()
' Close the connection when done with it.
