C# in a Nutshell, Second Edition

Name

CharEnumerator

Synopsis

This class allows you to access and iterate through individual chars in an array. You can manually retrieve a CharEnumerator from a String object using the String.GetEnumerator( ) method and then using the MoveNext( ) method to step through the string. However, C# provides built-in support with the convenient foreach statement, which uses a CharEnumerator transparently.

By convention, a CharEnumerator starts just before the first character. When using a CharEnumerator manually, you need to call the MoveNext( ) method before you can access the first character.

   public object Clone( ); 
// implements ICloneable
   public bool MoveNext( );
// implements IEnumerator
   public void Reset( );   
// implements IEnumerator
}
