Sharing project experience using C# to develop an electronic contract signing system

Introduction:
In the digital era, traditional paper contracts can no longer meet the needs of rapid business development need. As an efficient, environmentally friendly and safe contract signing method, electronic contracts have gradually attracted attention from all walks of life. As a C# developer, I was fortunate enough to participate in the development project of an electronic contract signing system. During this project, I gained some valuable experience, which I now share with you.

1. Demand Analysis
In the early stage of the project, we first communicate with the customer in detail to understand the customer's needs and expectations. We need to clarify the requirements for the function, interface, security and other aspects of the electronic contract signing system. During this process, we discussed and determined the following main functions with our customers:

1. User registration and login: Users can register an account and log in to the system to view and manage contracts.
2. Contract upload: Users can upload contract documents to the system and fill in relevant contract information.
3. Contract viewing: Users can view uploaded contract files and preview the contract.
4. Contract signing: Users can digitally sign contracts and generate signed electronic contract documents.
5. Contract review: The system administrator can review the signed contract to confirm the legality of the contract.
6. Contract management: Users can manage uploaded or signed contracts, such as downloading, deleting, etc.

2. Architecture design
According to customer needs, we designed the following system architecture:

1. Front-end interface: Use ASP.NET MVC to design the front-end page Set up to realize functions such as user registration, login, contract upload, viewing, and signing.
2. Back-end logic: Use C# to write back-end code to handle user requests and contract processing. Use ASP.NET Identity for user authentication and authorization management to ensure the security of user information.
3. Database design: Use SQL Server as the database to store user information, contract information and other data.
4. File storage: Store the uploaded contract files in the cloud storage service to ensure the security and reliability of the contract.
5. Signature authentication: Use digital certificates to digitally sign contracts to ensure the authenticity and integrity of the signed contract.

3. Development Practice
During the development process, we adopted an agile development method, decomposing the project into multiple small tasks and completing them step by step according to priority. The following are some of our practical experiences during the development process:

1. Teamwork: Close cooperation among team members is important. We keep teams flowing and working together through regular meetings, communication and collaboration tools.
2. Module independence: Divide the system functions into different modules, each module is responsible for a specific function, which can reduce the complexity of development and improve development efficiency.
3. Test-driven development: During the development process, we attach importance to unit testing and functional testing. The functionality of each module requires rigorous testing to ensure its correctness and reliability.
4. Coding standards: Writing high-quality code is a good habit. We use C# coding standards to keep the code readable and maintainable.

4. System deployment and maintenance
After completing the system development, we need to deploy the system to the server and ensure the stability and security of the system. Here are some suggestions:

1. Choose the appropriate server and operating system: Choose the appropriate server and operating system based on the system's needs and load to ensure that the system can run normally.
2. Configure security policy: Configure the security of the server, such as firewall settings, SSL certificate installation, etc., to protect the security of the system.
3. Regular backup and monitoring: Back up the system regularly to protect data security. At the same time, the operating status of the system is monitored to ensure the stability of the system.
4. Regular updates and optimization: Regularly update the system's dependent libraries and components, fix loopholes and BUGs, and perform performance optimization to improve system performance.

Conclusion:
Through the development experience of this project, I deeply understand the importance of electronic contract signing systems in modern business. Using C# to develop such a system can not only improve the efficiency of business processes, but also reduce costs and protect the environment. I hope my experience can provide some reference and help to other developers when developing similar systems.
