蓝墨云目前是免费且使用广泛的一个教学平台。但是普通用户目前只支持导入试题功能，却不支持把试题从蓝墨云上进行导出。
接下来，将实现导出的方法简要讲述一下：
①把蓝墨云上的试卷或测试导出
②导出的压缩包中有一个《汇总与详情》的Excel文件，这里包含了试题的全部内容。
③用C#编程读取《汇总与详情》的试题内容，生成符合试卷格式的文档。
接下来，我们就开始操作吧!
一、蓝墨云导出
步骤1：
步骤2：
步骤3：
步骤4：
二、解压
步骤1
步骤2：
步骤3：
三、通过编程希望达到的试卷输出效果（试卷样张）
四、程序界面如下：
小贴士：通过选择【显示答案】复选框，可以生成带答案的试卷。
五、程序代码如下：
