In This Topic

Reads a forward-only stream of rows from Zoho Desk.

Syntax

C#

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

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

Remarks

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

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

Example

The following example creates a ZohoDeskConnection, a ZohoDeskCommand, and a ZohoDeskDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the ZohoDeskDataReader, then the ZohoDeskConnection.

csharp

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

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

        Dim ZohoDeskCommand As ZohoDeskCommand = ZohoDeskConnection.CreateCommand()
                ZohoDeskCommand.CommandText = "SELECT AccountID, \"Account Name\", Phone FROM Accounts"
        ZohoDeskConnection.Open()
        Dim ZohoDeskReader As ZohoDeskDataReader = ZohoDeskCommand.ExecuteReader()
        Try
                ' Always call Read before accessing data.
                While ZohoDeskReader.Read()
                        Console.WriteLine(String.Concat(ZohoDeskReader.GetString(0), " ", _
                        ZohoDeskReader.GetString(1), " ", ZohoDeskReader.GetString(2)))
                End While
        Finally
                ' always call Close when done reading.
                ZohoDeskReader.Close()

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