C# 将多个GridView导出到excel客户端。

我想使用和导出按钮从我的网页导出数据。数据显示在3个不同的网格视图中，我希望将其分为3个不同的工作表“top 1、top 2、top 3”。我希望使用c#和asp.net实现客户端im。。我该怎么做？我可以使用java脚本吗

这是我的密码

{
    //3 gridviews each in 3 different worksheets
}

public override void VerifyRenderingInServerForm(Control control)

}


}

我建议使用这个组件，它是免费的，并且易于使用

用法：

    public static void GetExcel (DataTable sourceTable1,DataTable sourceTable2, DataTable sourceTable3, string fileName)
    {
        HSSFWorkbook workbook = new HSSFWorkbook();
        MemoryStream memoryStream = new MemoryStream();
        HSSFSheet sheet = workbook.CreateSheet("Sheet1") as HSSFSheet;
        HSSFSheet sheet2 = workbook.CreateSheet("Sheet2") as HSSFSheet;
        HSSFSheet sheet3 = workbook.CreateSheet("Sheet3") as HSSFSheet;
        HSSFRow headerRow = sheet.CreateRow(0) as HSSFRow;

        sheet.SetColumnWidth(0, 7000);
        sheet.SetColumnWidth(1, 7000);
        sheet.SetColumnWidth(2, 7000);
        sheet.SetColumnWidth(3, 10000);
        sheet.SetColumnWidth(4, 7000);

        sheet.DefaultRowHeight = 3000;


        HSSFPalette palette = workbook.GetCustomPalette();
        palette.SetColorAtIndex(HSSFColor.BLUE.index, 41, 113, 153);

这样行吗？有人能在我的代码中实现吗？该解决方案不是客户端，需要在服务器上安装excel。Excel不能在服务器上或批量使用。你必须使用第三方的选项，除非你想推出你自己的，我会继续下去，并猜测，不会让你走远。你有什么建议，使这容易工作？我应该将代码更改为clientside吗？我试过epplus，但我不明白它是如何工作的。如果您不介意获取xlsx（excel 2007+）文件，我建议您使用epplus。。否则，我喜欢下面建议的speti43。好吧，epplus似乎是最好的方式。但我仍然不知道如何将代码实现到我的代码中，以使其工作。我宁愿不使用第三方
