I think this is the better way to do it. Not sure why your code is displaying 0x000000001 in the hfc.GetKey(i) function, you need to investigate that.

C#

public class FileUploadList
        {
            public  int Position { get; set; }
            public string ControlId { get; set; }
            public string filePath { get; set; }
        }

        string path1, path2, path3, path4, path5, path6, path7, path8, path9, path10, path11, path12, path13, path14, path15,path16, path17, path18, path19, path20, path21, path22, path23, path24, path25 = null;

        /// <summary>
        /// save the file into folder and set the path
        /// </summary>
        /// <param name="hfc"></param>
        /// <param name="lstFile"></param>
        internal void FileUploadHelper(HttpFileCollection hfc, List<FileUploadList> lstFile)
        {
            if (lstFile.Count > 0 )
            {
                string fileExtension = string.Empty; 
                int fileSize = 0;
                int arrPos = 0;
                string[] arr = new string[5];

                foreach (FileUploadList file in lstFile)
                {
                    string filePath = file.filePath;

                    fileExtension = System.IO.Path.GetExtension(hfc[file.Position].FileName);
                    fileSize = hfc[file.Position].ContentLength;
                    if (hfc[file.Position].ContentLength > 0)
                    {
                        hfc[file.Position].SaveAs(Server.MapPath(string.Format("~/{0}/", filePath)) + System.IO.Path.GetFileName(hfc[file.Position].FileName));

                        string path = string.Format("{0}/{1}", filePath, System.IO.Path.GetFileName(hfc[file.Position].FileName));

                        arr[arrPos] = path;
                        arrPos++;
