convert with generics

clipped from nayyeri.net Who has said we should write a simple code?!!  I used List<T>.ConvertAll() function to get a List<String> from a List<Double> then converted my List<String> to an Array of Strings. List<T>.ConvertAll() method is a new .NET 2.0 Generic method which gets a System.Converter object and converts each element in a List<T> from type T to the outgoing type.  It seems this method is using a predicate but actually it doesn't do this. public String Points {     get     {         return String.Join(" | ",             (String[])this.myStudent.Points.ConvertAll             (new Converter<Double, String>(delegate(Double value)             {                 return Convert.ToString(value);             }             )).ToArray());     } }
