I will save in ArrayList in the file name of one folder.You can save the ArrayList in your database.You can check the following code.

//FIND ALL FILES IN FOLDER
System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(Server.MapPath("~/FolderName"));
ArrayList arrFilesName = new ArrayList();

if (fileUpload1.HasFile)
           {       
              
                  
                   string FolderName = "Gallery\\";
                   DirectoryInfo thisFolder = new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory + "\\Resources\\" + FolderName);
                   if (!thisFolder.Exists)
                   {
                       thisFolder.Create();
                   }
                   strunFilepath = "~/Resources/" + FolderName + "/" + FileName;
                   filename = "~/Resources/" + FolderName + FileName;
               }


               oHttpPostedFile.SaveAs(AppDomain.CurrentDomain.BaseDirectory + strunFilepath.Replace("~", ""));

要保存在数据库中，请保存文件名".

For saving in the database save ''filename'' .
