StringEnumerator.Reset Method

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 void Reset()

ExceptionCondition
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.

The following code example demonstrates several of the properties and methods of StringEnumerator.


using System;
using System.Collections.Specialized;

public class SamplesStringEnumerator  {

   public static void Main()  {

      // Creates and initializes a StringCollection.
      StringCollection myCol = new StringCollection();
      String[] myArr = new String[] { "red", "orange", "yellow", "green", "blue", "indigo", "violet" };
      myCol.AddRange( myArr );

      // Enumerates the elements in the StringCollection.
      StringEnumerator myEnumerator = myCol.GetEnumerator();
      while ( myEnumerator.MoveNext() )
         Console.WriteLine( "{0}", myEnumerator.Current );
      Console.WriteLine();

      // Resets the enumerator and displays the first element again.
      myEnumerator.Reset();
      if ( myEnumerator.MoveNext() )
         Console.WriteLine( "The first element is {0}.", myEnumerator.Current );

   }

}
