asp.net怎么调用另存功能

Answer 1

分情况 导出的时候就有类似弹出路径选择的对话框GridView   tmpGv   =   new   GridView(); 
                        DataSet   ds   =   new   DataSet(); 
                        SqlDataAdapter   da   =   new   SqlDataAdapter(cmd); 
                        da.Fill(ds,   "TitleName "); 
                        tmpGv.DataSource   =   ds; 
                        tmpGv.DataMember   =   "TitleName "; 
                        tmpGv.DataBind(); 
                        ToExcel(tmpGv,   "Daily "); 
////// 
public   void   ToExcel(System.Web.UI.Control   ctl,   string   FileName) 
        { 
                HttpContext.Current.Response.Charset   =   "UTF-8 ";//UTF-8 
                HttpContext.Current.Response.ContentEncoding   =   System.Text.Encoding.Default; 
                HttpContext.Current.Response.ContentType   =   "application/ms-excel "; 
                HttpContext.Current.Response.AppendHeader( "Content-Disposition ",   "attachment;filename= "   +   " "   +   FileName   +   ".xls "); 
                //ctl.Page.EnableViewState   =   true; 
                System.IO.StringWriter   tw   =   new   System.IO.StringWriter(); 
                HtmlTextWriter   hw   =   new   HtmlTextWriter(tw); 
                ctl.RenderControl(hw); 
                HttpContext.Current.Response.Write(tw.ToString()); 
                HttpContext.Current.Response.End(); 
        }   

Answer 2

先弹出保存对话框，
public void ToExcel(System.Web.UI.Control ctl, string FileName) 
  { 
  HttpContext.Current.Response.Charset = "UTF-8 ";//UTF-8 
  HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default; 
  HttpContext.Current.Response.ContentType = "application/ms-excel "; 
  HttpContext.Current.Response.AppendHeader( "Content-Disposition ", "attachment;filename= " + " " + FileName + ".xls "); 
  //ctl.Page.EnableViewState = true; 
  System.IO.StringWriter tw = new System.IO.StringWriter(); 
  HtmlTextWriter hw = new HtmlTextWriter(tw); 
  ctl.RenderControl(hw); 
  HttpContext.Current.Response.Write(tw.ToString()); 
  HttpContext.Current.Response.End(); 
  }
