C# 多个DataTable导入到Excel多张Sheet表
这个要引用Office组件的几个DLL文件,条件是先安装Office,而且Office要正确安装才可以
正确安装Office组件:http://blog.csdn.net/wxm3630478/article/details/5888375
测试Office版本: Office2007
添加引用 -- Com组件(Tab页) -- Microsoft Excel 12.0 ObjectLibrary -- 因为要向Excel插入图片,所以用Com组件
如果引用 -- .Net组件(Tab页) -- Microsoft.Office.Interop.Excel 版本14.0.0.0 ,则插入图片的方法处会报错,删除即可(如果不需要插入图片)
代码可以参考下,这个是我以前写的一个,是按照公司导出到Excel的格式写的,可以抽取一部分用
你先把数据分好类,放到不同的DataTable中,然后
TableToExcel类有构造函数需要参数 List
这个DataTable集合就会到出到不同的Sheet表,Sheet表的名字就是DataTable的Name属性,
如果Name为空,则是Table1~n
//调用:
List
DataTable table1 = new DataTable();
table1.Name = "鞋类"
dts.Add(table1);
dts.Add(table2);
dts.Add(table3);
//..........
TableToExcel ex = new TableToExcel("C:\\test.xls",dts)
ex.ExportExcel()
