Syntax

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

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

Remarks

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

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

Example

The following example creates a ZohoConnection, a ZohoCommand, and a ZohoDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the ZohoDataReader, then the ZohoConnection.

csharp

public void ReadMyData(string myConnString)  {
        ZohoConnection zohoConnection = new ZohoConnection(myConnString);
        ZohoCommand zohoCommand = (ZohoCommand)zohoConnection.CreateCommand();
        zohoCommand.CommandText = "SELECT AccountID, \"Account Name\", Phone FROM Accounts";
        zohoConnection.Open();
        ZohoDataReader zohoReader = zohoCommand.ExecuteReader();
        try {
                // Always call Read before accessing data.
                while (zohoReader.Read()) {
                Console.WriteLine(zohoReader.GetString(0) + " " + 
                zohoReader.GetString(1) + " " + zohoReader.GetString(2));
        }
        }
        finally {
                // always call Close when done reading.
                zohoReader.Close();

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

Visual Basic

Public Sub ReadMyData(ByVal myConnString As String)
        Dim zohoConnection As New ZohoConnection(myConnString)
        Dim zohoCommand As ZohoCommand = zohoConnection.CreateCommand()
                zohoCommand.CommandText = "SELECT AccountID, \"Account Name\", Phone FROM Accounts"
        zohoConnection.Open()
        Dim zohoReader As ZohoDataReader = zohoCommand.ExecuteReader()
        Try
                ' Always call Read before accessing data.
                While zohoReader.Read()
                        Console.WriteLine(String.Concat(zohoReader.GetString(0), " ", _
                        zohoReader.GetString(1), " ", zohoReader.GetString(2)))
                End While
        Finally
                ' always call Close when done reading.
                zohoReader.Close()

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