i am working with list and my list has 14 record.
List oProduct = new List { new Product(\"../images/1.jpg
The second parameter to GetRange needs to be the count of elements to get, so change it to 4 (I think that's what you want).
4
Also, the first parameter is the zero-based index, so you want GetRange(9, 4) to get images 10 through 13.
GetRange(9, 4)
