How to get items in a specific range (3 - 7) from list?

Question

What would be the most efficient way to select all the items in a specific range from a list and put it in a new one?

List<DataClass> xmlList = new List<DataClass>(); 

This is my List, and I would like to put all the DataClass items between the range (3 - 7) in a new List.

What would be the most efficient way? A foreach loop that that count++ everytime untill he reaches the items between a the range and add those items to the new list?

Answer 1

The method you are seeking is GetRange:

List<int> i = new List<int>(); List<int> sublist = i.GetRange(3, 4);  var filesToDelete = files.ToList().GetRange(2, files.Length - 2); 

From the summary:

// Summary: //     Creates a shallow copy of a range of elements in the source System.Collections.Generic.List<T>. // Parameters: //   index: //     The zero-based System.Collections.Generic.List<T> index at which the range //     starts. //   count: //     The number of elements in the range. 

Answer 2

If for any reason you don't like to use the GetRange method, you could also write the following using LINQ.

List<int> list = ... var subList = list.Skip(2).Take(5).ToList();
