将网格视图导出为Excel并将Excel文件保存到文件夹

Question

我想保存导出网格视图数据的excel文件.我已编写代码将gridview数据导出到excel但我不知道如何保存导出的文件.

以下是我将gridview导出到excel的代码:

Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("content-disposition", "attachment;filename=MyFiles.xls");
Response.Charset = "";
this.EnableViewState = false;
System.IO.StringWriter sw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);
gvFiles.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();

Answer 1

你可以这样做:

private void ExportGridView()
{
    System.IO.StringWriter sw = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);

    // Render grid view control.
    gvFiles.RenderControl(htw);

    // Write the rendered content to a file.
    string renderedGridView = sw.ToString();
    System.IO.File.WriteAllText(@"C:\Path\On\Server\ExportedFile.xlsx", renderedGridView);
}
