关于导入到Excel中的数字变成字符格式

关于导入到Excel中的数字变成字符格式 1、设置格式在 DataGrid_ItemDataBound(...)事件中 if(e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item) { e.Item.Cells[1].Attributes.Add ("style","vnd.ms-excel.numberformat:@"); e.Item.Cells[11].Attributes.Add ("style","vnd.ms-excel.numberformat:@"); } 2、这是DataGrid的下载 DataGrid1.Visible = true; DataGrid1.AllowPaging = false; DataGrid1.DataSource = DBHelper.ExecuteDataTable(ViewState["Exesql"].ToString(),CommandType.Text); DataGrid1.DataBind(); DateTime dt1 = DateTime.Now; //加上时间信息 string nowtime1 = dt1.Year.ToString()+dt1.Month.ToString()+dt1.Day.ToString()+dt1.Hour.ToString()+dt1.Minute.ToString()+dt1.Second.ToString(); Response.Clear(); Response.Buffer= true; Response.Charset="GB2312"; Response.AppendHeader("Content-Disposition","attachment;filename=huikuan"+nowtime1+".xls"); Response.ContentEncoding =System.Text.Encoding.GetEncoding("utf-8"); //Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文 Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 this.EnableViewState = false; System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true); System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad); System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter); this.DataGrid1.RenderControl(oHtmlTextWriter); Response.Write(oStringWriter.ToString()); Response.End(); DataGrid1.AllowPaging =true; this.DataGrid1.Visible= false;
