C#读写Excel文件、不需要office支持，可读取Excel文件到DataSet、DataTable中，也可以将内存表写入到Excel文件。包含几个dll组件和一个cs代码文件，有详尽注释，我自己经常用。不过导出的性能不好，如果是上万行的数据导出到Excel会很慢。-C# to read and write Excel files, no office support, you can read Excel files to DataSet, DataTable, you can also write to the memory table to an Excel file. Dll contains several components and a cs code file, there are detailed notes, I often use. However, export performance is not good, if it is thousands of rows of data exported to Excel will be very slow.
