Dynamic arrays are growable arrays and have an advantage over static arrays. This is because the size of an array is fixed.

To create arrays dynamically in C#, use the ArrayList collection. It represents ordered collection of an object that can be indexed individually. It also allows dynamic memory allocation, adding, searching and sorting items in the list.

The following is an example showing how to create arrays in dynamically in C#.

         ArrayList al = new ArrayList();
         al.Add(99);
         al.Add(47);
         al.Add(64);
         Console.WriteLine("Count: {0}", al.Count);
         Console.Write("List: ");
         foreach (int i in al) {
            Console.Write(i + " ");
         }
         Console.WriteLine();
         Console.ReadKey();
      }
   }
}
