	CanUpdate	* Member deprecated; see Remarks. * A Boolean that indicates whether the new package XML can update the old package XML.
	Equals	Determines whether two object instances are equal. (DtsObject에서 상속됨)
	Execute	Runs the task.
	Finalize	(Object에서 상속됨)
	GetConnectionID	Gets a String containing the ID of the connection.
	GetConnectionName	Gets a String containing the name of the connection.
	GetHashCode	Returns the hash code for this instance. (DtsObject에서 상속됨)
	GetType	(Object에서 상속됨)
	InitializeTask	Initializes the properties associated with the task. This method is called by the runtime and is not used in code.
	MemberwiseClone	(Object에서 상속됨)
	ToString	(Object에서 상속됨)

주의

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.

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

스레드 보안

이 유형의 모든 공용 static(Visual Basic에서는 Shared) 멤버는 스레드로부터 안전합니다. 인스턴스 멤버는 스레드로부터의 안전성이 보장되지 않습니다.
