Extension to mimic the old VB string function

  public static class BlahExtension

    {

       public static char[]  Space(this int cnt, char c = ' ' )

       {

           return Enumerable.Repeat(c,cnt).ToArray();  

       }

    }

or this:

 public static string Space(this int cnt, char c = ' ')
       {
            return new string(Enumerable.Repeat('f', 10).ToArray());
       }
