This article will introduce an open source online examination system based on .NET 6.0 and and discuss its various functions and its technical implementation principles. For those who need an online examination system , this article is a good learning resource , I hope to help you understand and master the construction of the system , so as to provide a convenient and efficient examination environment .
Projects
This system is designed to provide a comprehensive online examination solution for educational institutions, covering multiple modules such as question bank management, test paper management, examination management, results management and background management, so as to build a complete and efficient examination environment.
Question bank managementIt is one of the core functions of the system, which supports operations such as adding, deleting, modifying and querying of test questions, ensuring rich diversity and timely updating of test question resources. Through the fine question bank management, teachers can flexibly create or update test questions according to the syllabus and course requirements to meet the needs of different disciplines and difficulty levels.
Test paper managementThe function focuses on the operations of test paper generation, modification, deletion and query. Teachers can select test questions from the question bank according to preset rules and combine them into a test paper that meets the examination requirements. This flexible configuration of test papers not only improves the efficiency of question generation, but also provides students with a fair and impartial examination experience.
Examination managementFunctions then cover key aspects such as scheduling, monitoring and grading of exams. By setting the exam time, subjects and other information through the system, administrators can easily organize online exams, while students can participate in the exams within the stipulated time, ensuring the smooth running of the entire exam process. In addition, the automated grading mechanism further enhances the accuracy and speed of grading.

Project technology
development environment (computer)
- Development tools: Visual Studio 2022 version 16.8
- Backend Framework: .NET 6 SDK
- Cross-platform library: .NET Standard 2.1
- Database Operation Library: MySQL
- Object Mapping Tool: FurionMapster
MySQL Feature Highlights
MySQL is a powerful import/export general-purpose library that supports data manipulation in a variety of file formats, including but not limited to:
-
Dto Import and Export: Supports importing and exporting Data Transfer Objects (Dto) to and from files.
-
Template Export: Provides customized templates for flexible control of the format of the exported file.
-
Fancy Export: Supports advanced features such as style settings, image insertion, etc.
-
Dynamic export: Generate export files based on real-time data and user requirements.
Project framework
The overall architecture of the online examination system based on technologies such as .NET 6, Vue and ElementUI is shown in the following figure:
local environment
To build and test this online exam system in a local development environment, follow the steps below:
1、Initializing the database: First, place the file located in the./docker/mysql/init/ script file into the MySQL database to create the required database structure and initial data.
2、Open the back-end project: Use Visual Studio to open the file located in the./backend/ solution file, which is the back-end part of the system.
3、Configuring Database Connections: in project-based file to configure the database connection string for the development environment.
4、Installing front-end dependencies: Enter./frontend/admin cap (a poem)./frontend/teacher directory, run thenpm install to install the required dependencies for both front-end projects.
5、Starting a front-end project: in./frontend/admin cap (a poem)./frontend/teacher directory, run thenpm run dev Start the front-end development server.
6、Loading to the uniapp tool: Finally, it will be./frontend/examking-app The project is loaded into the uniapp developer tool and then run to the phone for testing.
In this way, you have finished setting up your local development environment and can start debugging and testing the system.
