Check File Type Code:-

bool CheckFileType(string fileName)

        {

            string ext = Path.GetExtension(fileName);

            switch (ext.ToLower())

            {

                case ".gif":

                    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.
