            int Total= 0,success= 0,unsuccess= 0;
            HttpFileCollection fileCollection = Request.Files;
            string notuploaded = string.Empty;
            for (int i = 0; i < fileCollection.Count; i++)
            {
                HttpPostedFile uploadfile = fileCollection[i];
                string fileName = Path.GetFileName(uploadfile.FileName);

                if (uploadfile.ContentLength < 5242880)
                {
                    if (CheckFileType(fileName))
                    {
                        string uploadpath = "~/Files/" + fileName;
                        fu_1.SaveAs(MapPath(uploadpath));
                        Total++;
                        success++;
                    }
                    else
                    {
                        Total++;
                        unsuccess++;
                    }
                }
                else
                {
                    Total++;
                    unsuccess++;
                }
            }
            lblmsz.Text = "<span style='color:Green;'>Total Files = " + Total + " Successful Uploads = " + success + "</span><span style='color:Red;'> Unsuccessful Uploads = " + unsuccess + "</span>";
         

        }

Check File Type Code:-

bool CheckFileType(string fileName)

        {

            string ext = Path.GetExtension(fileName);

            switch (ext.ToLower())

            {

                case ".gif":

                    return true;

                case ".png":

                    return true;

                case ".jpg":

                    return true;

                case ".jpeg":

                    return true;

                default:

                    return false;

            }

        }

Example:-

 1. Five files Selected 1 excel and 4 jpeg files

2.  Jpeg files are uploaded because Excel file allowed.
