Examples

To see this code in the context of a complete example, see the RepeaterItemCollection class topic.

      void GetEnumerator_Clicked(Object Sender, EventArgs e)
      {
labelDisplay.Text = "Invoking GetEnumerator method.<br />";
labelDisplay.Text += "The Items collection contains: <br />";

// Display the elements of the RepeaterItemCollection using GetEnumerator.
RepeaterItemCollection  myItemCollection = myRepeater.Items;
IEnumerator myEnumertor = myItemCollection.GetEnumerator();
while(myEnumertor.MoveNext())
{
   RepeaterItem myItem = (RepeaterItem)myEnumertor.Current;
   labelDisplay.Text += ((DataBoundLiteralControl)
      myItem.Controls[0]).Text + "<br />";
}
      }

Sub GetEnumerator_Clicked(Sender As [Object], e As EventArgs)
   labelDisplay.Text = "Invoking GetEnumerator method.<br />"
   labelDisplay.Text += "The Items collection contains: <br />"
   
   ' Display the elements of the RepeaterItemCollection using GetEnumerator.
   Dim myItemCollection As RepeaterItemCollection = myRepeater.Items
   Dim myEnumertor As IEnumerator = myItemCollection.GetEnumerator()
   While myEnumertor.MoveNext()
      Dim myItem As RepeaterItem = CType(myEnumertor.Current, RepeaterItem)
      labelDisplay.Text += CType(myItem.Controls(0), DataBoundLiteralControl).Text + "<br />"
   End While
End Sub 'GetEnumerator_Clicked

Remarks

Use this method to create a System.Collections.IEnumerator that can be used to iterate through each item in the RepeaterItemCollection.

Use the IEnumerator.Current property to get the item currently pointed to in the collection.

Use the IEnumerator.MoveNext method to move to the next item in the collection.

Use the IEnumerator.Reset method to move the enumerator back to the initial position.

Note

After you create a System.Collections.IEnumerator object or use the IEnumerator.Reset method to move the enumerator to the first item in the collection, you must call the IEnumerator.MoveNext method. Otherwise, the item represented by the IEnumerator.Current property is undefined.
