Sets the enumerator to its initial position, which is before the first element in the collection.

Namespace:   System.Collections.Specialized
Assembly:  System (in System.dll)

Public Sub Reset

Exception Condition
InvalidOperationException

The collection was modified after the enumerator was created.

Reset moves the enumerator to the beginning of the collection, before the first element. After Reset, MoveNext must be called to advance the enumerator to the first element of the collection before reading the value of Current.

Public Class SamplesStringEnumerator

   Public Shared Sub Main()

      ' Creates and initializes a StringCollection.
      Dim myCol As New StringCollection()
      Dim myArr() As [String] = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"}
      myCol.AddRange(myArr)

      ' Enumerates the elements in the StringCollection.
      Dim myEnumerator As StringEnumerator = myCol.GetEnumerator()
      While myEnumerator.MoveNext()
         Console.WriteLine("{0}", myEnumerator.Current)
      End While
      Console.WriteLine()

      ' Resets the enumerator and displays the first element again.
      myEnumerator.Reset()
      If myEnumerator.MoveNext() Then
         Console.WriteLine("The first element is {0}.", myEnumerator.Current)
      End If
