• 【C#】试卷批改系统

    简介

    实现语言：C#

    项目名称：试卷批改系统

    项目类型：Windows 窗体应用(.NET Framework)

    开发环境：Visual Studio 2022 Community 17.2.5 

    目标框架：.NET Framework 4.8

    项目介绍

    为了缓解老师们的疲劳，让我们更快乐得玩耍，我做了这个试卷批改的系统，能帮老师快速地批改选择题、判断题和有唯一答案的填空题，并且让我们有充分的时间玩耍，简直一举（没）两得（用）啊！

    好了，回到正题，其实是我一个老师用C++做了一个简单的试卷批改系统，但每次的答案都需手动输入，也不能一键批改，我就做了这么一个项目，支持直接导入老师文件（答案）与分数文件（每道题对应的分值写在这个文件中）与一键导入学生文件。

    •  2022-7-19：1.0.0正式版

            --忽略分数文件中的换行--

            --忽略老师文件和学生文件中的大小写--

    • 2022-7-18：1.0.0测试版

            --忽略老师文件和学生文件中的空格与换行--

    • 2022-7-16：创建项目

    运行截图

     先准备若干个个文本文档（由一个老师文档即答案、一个分数文件和若干个学生文件组成），内容如下：

     

    运行程序，选择“批改试卷”并按提示依次选择文件

     然后会弹出结果：

    然后我们在人工检验一下：

    • 学生1所有答案正确，忽略大小写和换行，应为满分即150分。
    • 学生2第二个答案和最后一个答案错误，忽略空格和换行，共减去40分，应得110分。

    由此看来程序运行无误。
