If you want to save file in server

IoC Configuration and Usage of FileService
This WebAPI project manages static files (wwwroot directory) using the Nlabs.FileService package. To utilize this package, you need to perform dependency injection (DI) and provide the necessary configuration.

Step 1: Adding Dependencies to IoC Container
In your Program.cs file, use the AddFileService method to configure the IFileHostEnvironment interface. This method ensures that the necessary dependencies are registered correctly in the IoC container:

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddFileService(builder.Environment.WebRootPath);



string filePath = "./Files/";


string fileName = FileService.FileSaveToServer(file,filePath);

If you want to save file in Ftp

FileSaveToFtpModel fileSaveToFtpModel = new("ftp.ftpadresiniz.com","userName", "password");

string fileName = FileService.FileSaveToFtp(file,fileSaveToFtpModel);

If you want to save file in Database (byte[])

byte[] fileByeArray = FileService.FileConvertByteArrayToDatabase(file);

If you want to delete file in server

//string path = "./Files/" + "FileName";

If you want to use the package using layered architecture
Example Handler Code:
internal sealed class MyCommandHandler(IFileHostEnvironment fileHostEnvironment) : IRequestHandler
bla bla bla
this handle code

var fullPath = Path.Combine(fileHostEnvironment.WebRootPath, "Files", file.jpeg);

FileService.FileDeleteToServer(path);

If you want to delete file in ftp

FileSaveToFtpModel fileSaveToFtpModel = new("ftp.ftpadresiniz.com","userName", "password");
string path = "./Files/" + "FileName";

FileService.FileDeleteToFtp(path,fileSaveToFtpModel);
