I need help with programming against the dnn file system io.

This is what I have discovered so far...

To add a directory I needed to use the core microsoft .net api.  Once I created the folder, I then had to add it (again) through the dotnetnuke api for it to be recognized by dotnetnuke (4.9.1)

I manually added a file and it does not show up in the file list-- FileController.GetAllFiles(portalID);

here is the code:

                        try
                        {
                            int success;

                            DotNetNuke.Services.FileSystem.FileController myFileController = new FileController();
                            DotNetNuke.Services.FileSystem.FolderController myFolderController = new FolderController();
                            DotNetNuke.Services.FileSystem.FolderInfo myFolderInfo = null;

                            Dictionary<string, FolderInfo> myFolderInfos = myFolderController.GetFolders(this.PortalId);
                            if (myFolderInfos != null && myFolderInfos.Count > 0)
                            {
                                if (myFolderInfos.ContainsKey("ProfileImages/"))
                                {
                                    myFolderInfo = myFolderInfos["ProfileImages/"];
                                }
                            }
                            if (myFolderInfo == null)
                            {

                                try
                                {
                                    if (!Directory.Exists(Server.MapPath("~/Portals/0/ProfileImages")))
                                    {

                                        Directory.CreateDirectory(Server.MapPath("~/Portals/0/ProfileImages"));
                                        success = myFolderController.AddFolder(this.PortalId, "ProfileImages");
                                    }
                                }
                                catch (IOException ioe)
                                {

                                }
                               
                                myFolderInfos = myFolderController.GetFolders(this.PortalId);
                                if (myFolderInfos != null && myFolderInfos.Count > 0)
                                {
                                    if (myFolderInfos.ContainsKey("ProfileImages/"))
                                    {
                                        myFolderInfo = myFolderInfos["ProfileImages/"];
                                    }
                                }

                            }
                            if (myFolderInfo != null)
                            {

                                DataTable myfiles = myFileController.GetAllFiles();
                               if (myfiles != null && myfiles.Rows.Count > 0)
                                {
                                    MyFiles.DataSource = myfiles;
                                    MyFiles.DataBind();
                                }
                            }
                        }
                        catch (Exception innerE) { }


                    }
                    catch { }

The folder now exists on my system with one image in it.  FolderID is 27, PortalID is 0, StorageLocation is 0

Here is a screen shot of the results

any help would be appreciated

 

 

Note also that the shared method FileSystemUtils.AddFolder will both create the physical folder and add the appropriate entry to the DNN Folders table.

If you are saving a file that you have uploaded using an HttpFileUpload control, you may also want to consider using the shared method FileSystemUtils.UploadFile to both save the physical file and add the appropriate entry to the DNN Files table. Otherwise, you will have to use one of the AddFile methods on an instance of the FileController class to add the entry to the DNN Files table.

One other tip for you that I forget if I have not been working with the FolderController method for a while: all of the DNN methods in which a folder path is specified expect the path will end with a forward slash, for example "ProfileImages/"
