using  System.Collections;  
  
class  MyClass  {  
    char[]  chrs  =  {  'A',  'B',  'C',  'D'  };  
  
    public  IEnumerator  GetEnumerator()  {  
        foreach(char  ch  in  chrs)  
            yield  return  ch;  
    }  
}  
  
class  MainClass  {  
    public  static  void  Main()  {  
        MyClass  mc  =  new  MyClass();  
  
        foreach(char  ch  in  mc)  
            Console.Write(ch  +  "  ");  
  
        Console.WriteLine();
