ExactTargetDataReader Class
Reads a forward-only stream of rows from ExactTarget.
Syntax
'Declaration
 
Public NotInheritable Class ExactTargetDataReader 
   Inherits Devart.Data.SqlShimDataReader
   Implements System.Collections.IEnumerableSystem.Data.IDataReaderSystem.Data.IDataRecordSystem.IDisposable 
 
Remarks
To create a ExactTargetDataReader, you must call the ExecuteReader method of the ExactTargetCommand object, rather than directly using a constructor.

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

Example
The following example creates a ExactTargetConnection, a ExactTargetCommand, and a ExactTargetDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the ExactTargetDataReader, then the ExactTargetConnection.
public void ReadMyData(string myConnString)  {
        ExactTargetConnection exactTargetConnection = new ExactTargetConnection(myConnString);
        ExactTargetCommand exactTargetCommand = (ExactTargetCommand)exactTargetConnection.CreateCommand();
        exactTargetCommand.CommandText = "SELECT ID, Name, Subject FROM Email";
        exactTargetConnection.Open();
        ExactTargetDataReader exactTargetReader = exactTargetCommand.ExecuteReader();
        try {
                // Always call Read before accessing data.
                while (exactTargetReader.Read()) {
                Console.WriteLine(exactTargetReader.GetInt32(0).ToString() + " " + 
                exactTargetReader.GetString(1) + " " + exactTargetReader.GetString(2));
        }
        }
        finally {
                // always call Close when done reading.
                exactTargetReader.Close();

                // Close the connection when done with it.
                exactTargetConnection.Close();
        }
}
Public Sub ReadMyData(ByVal myConnString As String)
        Dim exactTargetConnection As New ExactTargetConnection(myConnString)
        Dim exactTargetCommand As ExactTargetCommand = exactTargetConnection.CreateCommand()
                exactTargetCommand.CommandText = "SELECT ID, Name, Subject FROM Email"
        exactTargetConnection.Open()
        Dim exactTargetReader As ExactTargetDataReader = exactTargetCommand.ExecuteReader()
        Try
                ' Always call Read before accessing data.
                While exactTargetReader.Read()
                        Console.WriteLine(String.Concat(exactTargetReader.GetInt32(0).ToString(), " ", _
                        exactTargetReader.GetString(1), " ", exactTargetReader.GetString(2)))
                End While
        Finally
                ' always call Close when done reading.
                exactTargetReader.Close()

                        ' Close the connection when done with it.
                        exactTargetConnection.Close()
        End Try
End Sub
