我有一个用于将数据导出到excel的方法。直到现在我一直在将表格传递给该方法。但是现在我希望传递网格数据,这样我就不必为不同的实例调用程序来获得不同的结果过滤的数据集。有办法吗?

    public void ExportToExcel(DataSet ds)
    {
        if (ds.Tables[0].Rows.Count > 0)
        {

            string filename = ds.Tables[1].Rows[0]["filename"].ToString() + ".xls";
            System.IO.StringWriter tw = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
            DataGrid dgGrid = new DataGrid();
            dgGrid.DataSource = ds.Tables[0];
            dgGrid.DataBind();
            //Get the HTML for the control.
            dgGrid.RenderControl(hw);
            //Write the HTML back to the browser.
            //Response.ContentType = application/vnd.ms-excel;
            Response.Clear();
            Response.ClearHeaders();
            Response.Charset = "";
            Response.AddHeader("content-disposition", String.Concat("attachment;filename=", filename));
            Response.AddHeader("Cache-Control", "max-age=0");
            Response.ContentType = "application/vnd.xls";
            // this.EnableViewState = false;
            Response.Write(tw.ToString());
            Response.End();
        }
    }

这是我用来导出到 excel 的方法。
