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


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

Remarks

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

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

Example

The following example creates a ZohoBooksConnection, a ZohoBooksCommand, and a ZohoBooksDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the ZohoBooksDataReader, then the ZohoBooksConnection.

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

public void ReadMyData(string myConnString)  {
        ZohoBooksConnection ZohoBooksConnection = new ZohoBooksConnection(myConnString);
        ZohoBooksCommand ZohoBooksCommand = (ZohoBooksCommand)ZohoBooksConnection.CreateCommand();
        ZohoBooksCommand.CommandText = "SELECT AccountID, \"Account Name\", Phone FROM Accounts";
        ZohoBooksConnection.Open();
        ZohoBooksDataReader ZohoBooksReader = ZohoBooksCommand.ExecuteReader();
        try {
                // Always call Read before accessing data.
                while (ZohoBooksReader.Read()) {
                Console.WriteLine(ZohoBooksReader.GetString(0) + " " +

                // Close the connection when done with it.
