Paging without database in asp.net

Paging process need to implement based on files in a directory. The following method will return 3(pagesize) FileInfo objects based on pageIndex from a specific directory.

private IList<FileInfo> GetFiles(string directory, int pageIndex)
{
    var fileInfoList = new List<FileInfo>();
    int pageSize = 3;//Assume that page size is 3
    string[] fileFullNames = Directory.GetFiles(directory);

    int start =  pageIndex * pageSize ;
    int loopCounter = 0;
    for (int index = start; index < fileFullNames.Count(); index++)
    {
        fileInfoList.Add(new FileInfo(fileFullNames[index]));
        loopCounter++;
        if (loopCounter == pageSize)
            break;
    }
    return fileInfoList;
}

Client code as follows

IList<FileInfo> page1 = GetFiles("D:\\FileList", 0);
IList<FileInfo> page2 = GetFiles("D:\\FileList", 1);
IList<FileInfo> page3 = GetFiles("D:\\FileList", 2);
IList<FileInfo> page4 = GetFiles("D:\\FileList", 3);

Your client code may be differ based on control you use for. Like gridview/client side table etc just you adjust these code. I show here how to call that paging method 3 times with different page index; I test it with create a directory and save 10 different files there and pick files page by page.
