通过浏览器将多个工作表导出到Excel

我需要将多个数据表导出到客户端计算机上的Excel中，每个数据表分配给自己的工作表。 如果只是一张纸，我会使用Excel / csv内容types，但是我听说过一些可以代表整个工作簿的XML格式。 我不想下载Packaging和.xlsx路由，所以我需要标准的.xls。

我们的错误跟踪器Gemini曾经有一个导出function，可以生成一个XML文件，Excel可以自动作为多页工作簿打开，但是我找不到它。 还有这样一个机制，我在哪里可以find这个模式？

Answer 1

如果您不想创build自己的Excel XML编写器库，则可以使用此库。

Answer 2

在Excel中，您可以将工作簿保存为XML格式。 （在Excel 2007中称为XML Spreadsheet 2003）。

这可能会让你开始。

使用下面在单独的类文件和page.cs文件粘贴button单击这样的function： ExcelHelperNS.ExcelHelper.ToExcel（Dataset1，“ExcelFileName”，Page.Response）;

在单独的类中使用它，它将工作..

看下面的链接。

使用这种方式，你可以创build一个XML数据集…如果你的数据是巨大的…你可以使用response.write写每个XMLstring到客户端，使服务器的内存使用可以大大减less。
