Generic + extension method to create a simple paging class (C #)

Create a new class named PagedList and inherit from List <T>

Code
1 public class PagedList <T>: List <T>
2 {
3 /// <summary>
4 // page number
5 /// </summary>
6 public int PageIndex {get; set ;}
7
8 /// <summary>
9 // page size
10 /// </summary>
11 public int PageSize {get; set ;}
12
13 /// <summary>
14 // total number of elements
15 /// </summary>
16 public int TotalCount {get; set ;}
17
18 /// <summary>
19 // page number
20 /// </summary>
21 public int PageCount {get; set ;}
22
23 /// <summary>
24 // Constructor
25 /// </summary>
26 /// <param name = "list"> linked list </param>
27 /// <param name = "intPageIndex"> NO. </param>
28 /// <param name = "intPageSize"> size </param>
29 public PagedList (List <T> list, int intPageIndex, int intPageSize)
30 {
31 PageIndex = intPageIndex;
32 PageSize = intPageSize;
33
34 GetPagedList (list );
35}
36
37 // <summary>
38 // convert to pagination
39 /// </summary>
40 /// <param name = "list"> linked list </param>
41 private void GetPagedList (List <T> list)
42 {
43 int intStart = (PageIndex-1) * PageSize;
44
45 for (int I = intStart; I <intStart + PageSize & I <list. Count; I ++)
46 {
47 This. Add (list [I]);
48}
49
50 totalcount = List. count;
51 pagecount = totalcount/pagesize + 1;
52}
53}

Create a new class named PagedListExpansion.

Code
Public static class pagedlistexpansion
{
Public static PagedList <T> ToPagedList <T> (this List <T> list, int intPageIndex, int intPageSize)
{
Return new PagedList <T> (list, intPageIndex, intPageSize );
}
}

This simple paging class is complete.

Call:

Code
List <int> list = new List <int> ();
PagedList <int> page = list. ToPagedList <int> (1, 10 );

Such paging classes can be used for all types of linked lists. This is just an enlightening Demo. Please point out any errors. There are better ways to solve them. Remember to propose them.
