    FreshBooksDataReader Class
    In This Topic
    Reads a forward-only stream of rows from FreshBooks.
    Syntax
    Remarks
    To create a FreshBooksDataReader, you must call the ExecuteReader method of the FreshBooksCommand object, rather than directly using a constructor.

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

    Example
    The following example creates a FreshBooksConnection, a FreshBooksCommand, and a FreshBooksDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the FreshBooksDataReader, then the FreshBooksConnection.
    public void ReadMyData(string myConnString)  {
            FreshBooksConnection freshbooksConnection = new FreshBooksConnection(myConnString);
            FreshBooksCommand freshbooksCommand = (FreshBooksCommand)freshbooksConnection.CreateCommand();
            freshbooksCommand.CommandText = "SELECT Id, FirstName, LastName FROM Client";
            freshbooksConnection.Open();
            FreshBooksDataReader freshbooksReader = freshbooksCommand.ExecuteReader();
            try {
                    // Always call Read before accessing data.
                    while (freshbooksReader.Read()) {
                    Console.WriteLine(freshbooksReader.GetString(0) + " " + 
                    freshbooksReader.GetString(1) + " " + freshbooksReader.GetString(2));
            }
            }
            finally {
                    // always call Close when done reading.
                    freshbooksReader.Close();
    
                    // Close the connection when done with it.
                    freshbooksConnection.Close();
            }
    }
    Public Sub ReadMyData(ByVal myConnString As String)
            Dim freshbooksConnection As New FreshBooksConnection(myConnString)
            Dim freshbooksCommand As FreshBooksCommand = freshbooksConnection.CreateCommand()
                    freshbooksCommand.CommandText = "SELECT Id, FirstName, LastName FROM Client"
            freshbooksConnection.Open()
            Dim freshbooksReader As FreshBooksDataReader = freshbooksCommand.ExecuteReader()
            Try
                    ' Always call Read before accessing data.
                    While freshbooksReader.Read()
                            Console.WriteLine(String.Concat(freshbooksReader.GetString(0), " ", _
                            freshbooksReader.GetString(1), " ", freshbooksReader.GetString(2)))
                    End While
            Finally
                    ' always call Close when done reading.
                    freshbooksReader.Close()
    
                            ' Close the connection when done with it.
                            freshbooksConnection.Close()
            End Try
