예

The following code example is a very simple task implementation for a custom task that inherits from Task.

using System;
using Microsoft.SqlServer.Dts.Runtime;

class MyTask : Task
{
    private int m_value = 123;

    public override DTExecResult Execute(Connections connections,
Variables variables, IDTSEvents events,
IDTSLogging log, int lastExecResult, DtsTransaction txn)
    {
        return m_value;
    }
}

Imports System
Imports Microsoft.SqlServer.Dts.Runtime
 
Class MyTask
    Inherits Task
    Private m_value As Integer =  123 
    Public Overrides DTExecResult Property connections,() As Execute(Connections
    End Property
Variables variables, IDTSEvents events,
IDTSLogging log,int Function txn)() As lastExecResult,DtsTransaction
        Return m_value
End Function
End Class
