Question

我有下面的代码，单击时会生成一个excel文件。代码运行正常，颜色的格式很好。网格视图的数据前导零没有显示在excel中，长数字“106638660952840428”显示为1.06639E + 17，值为106638660952840000，因此它也会丢失其最后四位数字。我尝试了几种方法来导出具有相同结果的所有方法。我这样做是为了有机会单独格式化单元格。所以问题是有没有人知道如何动态更改格式，以便不会出现这些问题？另外要添加的是网页浏览器中的网格视图确实正确显示数据。

    protected void LinkButton6_Click(object sender, EventArgs e)
    {
        Iframe1.Attributes.Add("src", "blank.aspx");

        if (CheckBox5.Checked || CheckBox6.Checked)
        {
            dt = (DataTable)Cache["dtable"];
            Response.Clear();
            Response.Buffer = true;
            Response.AddHeader("content-disposition", "attachment;filename=BemisInventory.xls");
            Response.Charset = "";
            Response.ContentType = "application/vnd.ms-excel";
            using (StringWriter sw = new StringWriter())
            {
                HtmlTextWriter hw = new HtmlTextWriter(sw);

                //To Export all pages
                GridView1.AllowPaging = false;
                GridView1.DataSource = dt;
                //GridView1.PageIndex = 0;
                GridView1.DataBind();

                GridView1.HeaderRow.BackColor = Color.White;
                foreach (TableCell cell in GridView1.HeaderRow.Cells)
                {
                    cell.BackColor = Color.White;//GridView1.HeaderStyle.BackColor;
                }
                foreach (GridViewRow row in GridView1.Rows)
                {
                    row.BackColor = Color.White;
                    foreach (TableCell cell in row.Cells)
                    {
                        if (row.RowIndex % 2 == 0)
                        {
                            cell.BackColor = Color.White;
                        }
                        else
                        {
                            cell.BackColor = Color.White; //GridView1.RowStyle.BackColor;
                        }
                        cell.CssClass = "textmode";
                    }
                }

                GridView1.RenderControl(hw);

                //style to format numbers to string
                string style = @"<style> .textmode { } </style>";
                Response.Write(style);
                Response.Output.Write(sw.ToString());
                Response.Flush();
                Response.End();
            }

        }            
    }

Answer 1

通过添加：string style = @＆＃34; .textmode {mso-number-format：\ @; }＆＃34 ;;提出警告，但所有数据都在那里。
