尝试导出快速报告报告时找不到元数据文件 'Microsoft.CSharp' 错误
Getting a Metadata file 'Microsoft.CSharp' could not be found error upon trying to export a fastreport report
尝试使用 fastreport 开源版本准备报告并将其导出为 pdf
使用 Microsoft Sql Server 数据库作为它的数据源
我的代码似乎连接到数据库并能够填充数据源，所以问题很可能出在创建报告本身的代码中，但我不确切地看到它可能发生在哪里
异常发生在report.Prepare()；
以及它之后的那一行

而且我设法修复了它
基本上该错误的原因是使用了错误类型的 sqlconnection
重新编写了代码
