GetEnumerator méthode

Retrieves a TaskInfoEnumerator for use in iterating over the TaskInfos collection.

Espace de noms :  Microsoft.SqlServer.Dts.Runtime
Assembly :  Microsoft.SqlServer.ManagedDTS (dans Microsoft.SqlServer.ManagedDTS.dll)

Syntaxe

'Déclaration
Public Function GetEnumerator As TaskInfoEnumerator
'Utilisation
Dim instance As TaskInfos
Dim returnValue As TaskInfoEnumerator

returnValue = instance.GetEnumerator()

public TaskInfoEnumerator GetEnumerator()

public:
TaskInfoEnumerator^ GetEnumerator()

member GetEnumerator : unit -> TaskInfoEnumerator 

public function GetEnumerator() : TaskInfoEnumerator

Notes

The TaskInfoEnumerator is initially positioned before the first TaskInfo in the collection. Reset also returns the enumerator to this position. If the enumerator is located at this position, calling Current throws an exception.

Exemples

The following code sample creates a TaskInfoEnumerator using the GetEnumerator method, and then iterates over the collection.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

namespace TaskInfos_Item
{
    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            TaskInfos tInfos = app.TaskInfos;
            //Create the Enumerator.
            TaskInfoEnumerator myEnumerator = tInfos.GetEnumerator();
            Console.WriteLine("The collection contains the following values:");
            int i = 0;
            while ((myEnuemrator.MoveNext()) && (myEnuemrator.Current != null))
                Console.WriteLine("[{0}] {1}", i++, myEnuemrator.Current.Name);
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace TaskInfos_Item
    Class Program
        Shared  Sub Main(ByVal args() As String)
            Dim app As Application =  New Application() 
            Dim tInfos As TaskInfos =  app.TaskInfos 
            'Create the Enumerator.
            Dim myEnumerator As TaskInfoEnumerator =  tInfos.GetEnumerator() 
            Console.WriteLine("The collection contains the following values:")
            Dim i As Integer =  0 
            While (myEnuemrator.MoveNext()) &&(myEnuemrator.Current <> Nothing)
            Console.WriteLine("[{0}] {1}",i = Console.WriteLine("[{0}] {1}",i + 1
            End While
        End Sub
    End Class
End Namespace

Sample output:

The collection contains the following values:

[0] Execute Package Task

[1] Data Flow Task

[2] SQL Server Analysis Services Execute DDL Task

[3] SQL Server Analysis Services Processing Task

[4] Bulk Insert Task

[5] Data Mining Query Task

[6] Execute Process Task

[7] File System Task

[8] File Transfer Protocol Task
