Implementation of the Winform program for file management based on Service (Web Service) and winform for file management

Implementation of the Winform program for file management based on Service (Web Service) and winform for file management
1. Description

A Service-Oriented Architecture (SOA) is a component model that associates different functional units (called services) of an application with well-defined interfaces and contracts between these services. Interfaces are defined in a neutral way. They should be independent of the hardware platform, operating system, and programming language that implements services. This allows services built in a variety of systems to interact in a unified and universal manner.

The file management of this program uses the file classification method to manage files, so that one file can only be contained in one folder. You can manage files by file category. files can be divided into multiple categories, but they do not belong to any category. This increases the flexibility of file management. This document management service manages multipart upload and download of large files to achieve resumable upload and download of files.

2. Introduction to the File Management Service

The File Management Service uses the Web Service program developed by VS2008 C.
