Netigent.Utils.FileStoreIO 1.4.4

FileStoreIOClient

A generic layer to allow the saving and loading of files from configurable stores using a unique fileRef with prefix code for detection in your code.
Supports UNC (FileSystem), Database, Box, and AWS S3 Buckets.

How to Use

Thanks for considering this library — we hope it saves you time and simplifies file handling!

The library supports multiple storage providers (Database, FileSystem/UNC, Box, AWS S3) and uses a consistent fileRef (e.g., _$uniqueid) for all operations.

Database Notes

The library auto-creates and upgrades the FileStoreIndex table in the specified schema.
You can safely drop unused legacy columns: [FileType], [MainGroup], [SubGroup], [PathTags] — they are no longer used.

Quick Start

Direct Usage (keeping last 3 versions)

// Example configuration objects (use your real values!)
var myBoxConfig = new BoxConfig { /* ... your Box settings ... */ };
var myS3Config  = new S3Config  { /* ... your S3 settings ... */ };
var myFsConfig  = new FileSystemConfig { RootFolder = @"C:\temp\Files\", StoreFileAsUniqueRef = false };

var fileStoreIOClient = new FileStoreIOClient(
    appPrefix: "MyApp",
    databaseConnection: "Server=.;Database=myDb;Trusted_Connection=True;",
    maxVersions: 3,
    dbSchema: "filestore",
    defaultFileStore: FileStorageProvider.FileSystem,  // or S3, Database, Box
    boxConfig: myBoxConfig,
    s3Config: myS3Config,
    fileSystemConfig: myFsConfig);

// Example: Get a file by ref
var file = await fileStoreIOClient.File_GetAsyncV2("_$23fe627c5a5b410aa6017db308b71077");

Registering in Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    // Inject FileStoreIOClient provider
    services.Configure<FileStoreIOConfig>(Configuration.GetSection(FileStoreIOConfig.Section));
    services.AddSingleton<Netigent.Utils.FileStoreIO.IFileStoreIOClient, FileStoreIOClient>();
}

Usage in a Controller Example

using Netigent.Examples.UploadApp.Models;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Netigent.Utils.FileStoreIO;
using Netigent.Utils.FileStoreIO.Enums;
using System.Threading.Tasks;

namespace Netigent.Examples.UploadApp.Controllers
{
    public class HomeController : Controller
    {
        private readonly IFileStoreIOClient _ioClient;

        public HomeController(IFileStoreIOClient fileStoreIOClient)
        {
            _ioClient = fileStoreIOClient;
        }

        public async Task<IActionResult> Index()
        {
            ViewBag.Message = TempData["Message"];
            return View(new FileUploadViewModel { Files = await _ioClient.Files_GetAll() });
        }

        [HttpPost]
        [ActionName("Upload")]
        public async Task<IActionResult> Upload(IFormFile selectedFile, string location = "database", string description = "", string customerCode = "", string itemType = "")
        {
            var uploadLocation = (location ?? "").Equals("Database", StringComparison.CurrentCultureIgnoreCase)
                ? FileStorageProvider.Database
                : FileStorageProvider.FileSystem;

            var uploadedCode = await _ioClient.File_UpsertAsync(selectedFile, uploadLocation, description: description, customerCode, itemType);

            TempData["Message"] = $"File successfully uploaded to {uploadLocation} {uploadedCode}";

            // Setting success properties
            TempData["FileId"] = uploadedCode;
            TempData["FileLink"] = $"https://localhost:44317/Home/GetFile/{uploadedCode}";

            // Example: render dynamic images from FileStoreIOClient
            // e.g. <img src="@TempData["FileLink"]" style="height: 100px; width: auto;" />

            return RedirectToAction("Index");
        }

        public async Task<IActionResult> GetFile(string id)
        {
            var file = await _ioClient.File_Get(id);
            if (file == null) return NotFound();

            return File(file.Data, file.ContentType, file.Name);
        }

        public async Task<IActionResult> DeleteFile(string id)
        {
            // var xyz = await something();  // Remove or replace placeholder
            var fileInfo = await _ioClient.File_DeleteAsync(id);
            return RedirectToAction("Index");
        }
    }
}

Version History Highlights

1.4.4
Fixed License link in README.

1.4.3
Fixed License link in README.

1.4.2
Added MimeType helper for SVG = image/svg+xml (see changes in 1.4.0).

1.4.1
Bug fix on absolute paths in FileSystem storage (see changes in 1.4.0).

1.4.0

• Marked old methods as obsolete:

  List<InternalFileModel> Files_GetAllV2(string[] pathTags, bool recursiveSearch = false);
  List<InternalFileModel> Files_GetAllV2(string relationalFilePathAndName, bool recursiveSearch = false);
  

  Use these clearer alternatives instead:

  List<FileStoreItem> Files_GetByFolder(string folderPath, bool includeSubFolders = false);
  List<FileStoreItem> Files_GetByFileAndFolder(string folderPath, bool includeSubFolders, string fileToFind, bool exactFileMatch);
  

• Removed Microsoft.AspNetCore.Http.Features dependency (Upsert methods for IFormFile removed — use byte[] directly):

  IFormFile myFile = ...;  // from HttpRequest
  
  using var dataStream = new MemoryStream();
  await myFile.CopyToAsync(dataStream);
  string fileRef = await fileStoreIOClient.File_UpsertAsyncV2("HT/Training/myprocedures.pdf", dataStream.ToArray());
  

• Renamed models for clarity:
  FileObjectModel → FileOutput (simple output for sending to clients)
  InternalFileModel → FileStoreItem (full record from FileStoreIndex table)
• FileStoreIndex table now uses Folder column (PathTags deprecated but kept for reference).

1.3.0
Added support for relocating files:

Task<ResultModel> File_MoveAsync(string fileRef, string[] pathTags);
Task<ResultModel> File_MoveAsync(string fileRef, string relationalFilePathAndName);

1.2.1
Bug fix: Subfile replaced by single Parent. RecursiveSearch = false is now default.

1.2.0
Added recursive flag to Files_GetAllV2. Removed obsolete legacy methods.

1.1.7
Bug fix for AppPrefix not populating correctly. Upgraded to .NET 8.0 LTS + package updates.

1.1.6
Database migration: Include AppPrefix in PathTags (run this SQL if files "disappeared" after v1.1.5):

UPDATE {schema}.[FileStoreIndex] 
SET PathTags = '{AppPrefix}/' + PathTags 
WHERE PathTags NOT LIKE '{AppPrefix}%';

1.1.5
README updates and stabilization.

1.1.4
Internal database upgrade.

1.1.3
Added README.md to NuGet package.

(Older versions omitted for brevity — see commit history for full details.)
