  • Hi sudhanshuSharma

    You can write a custom multiple attachments form just like writing a Asp.Net multiple file upload form. The only difference between them is that the files are stored in items of SharePoint list as attachments.

    You can store file in an item as an attachment by writing following code:


                          SPList list = Web.Lists["ListName"];//get your list here
                            SPListItem Item = list.Items.Add();
                            FileStream file = File.OpenRead(FilePath)
                            byte[] bytes = new byte[file.Length];
                            file.Read(bytes, 0, bytes.Length);
                            SPAttachmentCollection attachments = Item.Attachments;
                            //add file to item
                            attachments.Add(AttachmentName, bytes);

    There are also many article about the multiple file upload such as this article. Hope that helps.
