Read Method (SqlShimDataReader)
public override bool Read()
'Declaration
Public Overrides Function Read() As Boolean
Return Value
true if there are more rows; otherwise, false.
The following example creates a
Devart.Data.Magento.MagentoConnection, a
Devart.Data.Magento.MagentoCommand, and a
SqlShimDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the
SqlShimDataReader, then the
Devart.Data.Magento.MagentoConnection.
public void ReadMyData(string myConnString)
{
string mySelectQuery = "SELECT customer_id, lastname FROM Customers";
MagentoConnection magentoConnection = new MagentoConnection(myConnString);
MagentoCommand magentoCommand = new MagentoCommand(mySelectQuery,magentoConnection);
magentoConnection.Open();
MagentoDataReader magentoReader;
magentoReader = magentoCommand.ExecuteReader();
// Always call Read before accessing data.
while (magentoReader.Read()) {
Console.WriteLine(magentoReader.GetString(0) + ", " + magentoReader.GetString(1));
}
// always call Close when done reading.
magentoReader.Close();
// Close the connection when done with it.
magentoConnection.Close();
}
