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)

Dim instance As Task
public abstract class Task : DtsObject,

The Task type exposes the following members.


  Name Description
Protected method Task Initializes a new instance of the Task class.



  Name Description
Public property ExecutionValue Returns a user-defined object. This field is read-only.
Public property Version *** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only.



  Name Description
Public method CanUpdate *** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML.
Public method Equals Determines whether two object instances are equal. (Inherited from DtsObject.)
Public method Execute Runs the task.
Protected method Finalize (Inherited from Object.)
Public method GetConnectionID Gets a String containing the ID of the connection.
Public method GetConnectionName Gets a String containing the name of the connection.
Public method GetHashCode Returns the hash code for this instance. (Inherited from DtsObject.)
Public method GetType (Inherited from Object.)
Public method InitializeTask Initializes the properties associated with the task. This method is called by the runtime and is not used in code.
Protected method MemberwiseClone (Inherited from Object.)
Public method ToString (Inherited from Object.)
Public method Update *** Member deprecated; see Remarks. ***    This method updates the old package XML with the new package XML if CanUpdate is set to true.
Public method Validate Verifies that the component is properly configured.



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.


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

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
