Examples

The following code sample creates an enumerator, and then uses the Current and MoveNext methods to navigate 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);  

            Console.WriteLine();  
        }  
    }  
}  

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  

            Console.WriteLine()  
        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

Remarks

After an enumerator is created, or after a call to the Reset method, the MoveNext method must be called to advance the enumerator to the first element of the collection before the enumerator can read the value of the Current property; otherwise, Current is undefined and throws an exception.

Current also throws an exception if the last call to MoveNext returned false, which indicates the end of the collection.

Current does not move the position of the enumerator, and consecutive calls to the Current return the same object until either MoveNext or Reset is called.

An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying, or deleting elements, the enumerator is invalidated and becomes irrecoverable; thus, the next call to MoveNext or Reset throws an InvalidOperationException. If the collection is modified between calls to MoveNext and Current, Current returns the element that it is set to, even if the enumerator has been invalidated.
