C# 使用Aspose.Cells 导出Excel的步骤及问题记录

今天在工作中碰到同事用了一种新型的方式导入excel,在此做个学习记录。

Aspose.Cells简介:Aspose.Cells是一款功能强大的Excel文档处理和转换控件,开发人员和客户电脑无需安装Microsoft Excel也能在应用程序中实现类似Excel的强大数据管理功能,支持所有Excel格式类型的操作,在没有Microsoft Excel的环境下,用户也可为其应用程序嵌入类似Excel的强大数据管理功能。

插件:Aspose.Cells

第一步:准备好导出的模板,例子:

此种当时的重点是Excel模板的数据绑定:

第一种:单个值的绑定
