[英]C#: Try to save Exported excel file but it save as Web Page(.html)
Below is my code used to export the excel file. 下面是我用于导出excel文件的代码。
public void ExportReport()
{
DataTable dataTable = new DataTable();
dataTable = getDataTable();
HttpResponse response = HttpContext.Current.Response;
GridView grdExportData = new GridView();
grdExportData.AllowPaging = false;
grdExportData.DataSource = dataTable;
grdExportData.DataBind();
//Clear the response and add the content types and headers to it.
response.Clear();
response.ClearContent();
response.ContentType = "application/octet-stream";
DateTime currDate = DateTime.Now;
response.AddHeader("Content-Disposition", "attachment; filename=report.xls")
// Create a dynamic control, populate and render it
GridView excel = new GridView();
excel.DataSource = dataTable;
excel.DataBind();
HtmlTextWriter htmlTextWriter = new HtmlTextWriter(response.Output);
htmlTextWriter.Write("<table><tr><td colspan='3'><b>Report Title</b></td><td colspan='1'></td><td colspan='1'><b>Date: </b></td><td colspan='1'>" + DateTime.Today.ToString("MM/dd/yyyy") + "</td></tr></table>");
excel.RenderControl(htmlTextWriter);
response.Flush();
response.End();
}
Code works and exported the report but when I modify the excel sheet in "ms excel" and try to save the file it saved as web page format. 代码可以正常工作并导出报告,但是当我在“ ms excel”中修改excel工作表并尝试将其保存为网页格式时保存文件。 I want default format as Excel.
我想要默认格式为Excel。
Thanks in advance. 提前致谢。
