别名与列中的空间使用linq和gridview导出excel

我需要导出Excel，我正在使用MVC4

这是我的代码

var co = from c in context.AN_COMPANY orderby c.COMPANY_DESCR select c; List<AN_COMPANY_EXT> societa_list = new List<AN_COMPANY_EXT>(); foreach (var o in co) { AN_COMPANY_EXT c_ex = new AN_COMPANY_EXT(o); societa_list.Add(c_ex); } GridView gv = new GridView(); gv.DataSource = (from d in societa_list select new { Codice = d.ID_COMPANY, Descrizione = d.COMPANY_DESCR, SAP_Alias = d.COMPANY_SAP_ALIAS, Booking_Company = d.IS_BOOKING_COMPANY }); gv.DataBind(); Response.Buffer = true; Response.AddHeader("content-disposition", "attachment; filename=AnagraficaSocieta.xls"); Response.ContentType = "application/ms-excel"; Response.Charset = ""; StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); gv.RenderControl(htw); Response.Output.Write(sw.ToString()); Response.Flush(); Response.End(); return RedirectToAction("Index"); 

如何设置列名与空间，例如“SAP ALIAS”，而不是SAP_ALIAS？
