Task Class

Defines an abstract class that implements the methods and properties common to all tasks in Integration Services. 

Namespace:  Microsoft.SqlServer.Dts.Runtime
Assembly:  Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)

Syntax

'Declaration
Public MustInherit Class Task _
    Inherits DtsObject _
    Implements IDTSManagedTask
'Usage
Dim instance As Task
public abstract class Task : DtsObject, 
    IDTSManagedTask
public ref class Task abstract : public DtsObject, 
    IDTSManagedTask
[<AbstractClassAttribute>]
type Task =  
    class
        inherit DtsObject
        interface IDTSManagedTask
    end
public abstract class Task extends DtsObject implements IDTSManagedTask

Remarks

A package consists of one or more tasks. These tasks define units of work that are performed as part of copying and transforming data, communicating with other processes, and performing database management functions.

Inherits from DtsObject and IDTSManagedTask.

Examples

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
