속성

  이름 설명
공용 속성 ExecutionValue Returns a user-defined object. This field is read-only.
공용 속성 Version *** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only.

메서드

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

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.

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.
