【转】excel表格导出集锦repeater实用，和普通用法

【http://www.cnblogs.com/s-y-l/archive/2011/12/23/2299008.html】

下面导出excel主要解决repeater产生乱码的问题

publicvoid CreateExcel(DataSet ds,string typeid,string FileName) 
        { 
            HttpResponse resp; 
            resp = Page.Response; 
            resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); 
            resp.AppendHeader("Content-Disposition", "attachment;filename="+ FileName); 
            string colHeaders="", ls_item=""; 
            int i=0; 

            //定义表对象和行对像，同时用DataSet对其值进行初始化 
            DataTable dt=ds.Tables[0]; 
            DataRow[] myRow=dt.Select(""); 
            // typeid=="1"时导出为EXCEL格式文档；typeid=="2"时导出为XML格式文档 
            if(typeid=="1") 
            { 
                //取得数据表各列标题，各标题之间以\t分割，最后一个列标题后加回车符 
                for(i=0;i<dt.Columns.Count;i++)
                {                    
                    if(i==dt.Columns.Count-1)
                    {
                        colHeaders +=dt.Columns[i].Caption.ToString() +"\n";    
                    }
                    else
                    {
                        colHeaders+=dt.Columns[i].Caption.ToString()+"\t"; 
                    }
                }
                //向HTTP输出流中写入取得的数据信息 
                resp.Write(colHeaders); 
                //逐行处理数据 
                foreach(DataRow row in myRow) 
                { 
                    //在当前行中，逐列获得数据，数据之间以\t分割，结束时加回车符\n 
                    for(i=0;i<dt.Columns.Count;i++) { if(i==dt.Columns.Count-1)
                        {
                            ls_item += row[i].ToString() +"\n"; 
                        }
                        else
                        {
                            ls_item +=row[i].ToString() +"\t";  
                        }
                    }
                    //当前行数据写入HTTP输出流，并且置空ls_item以便下行数据 
                    resp.Write(ls_item); 
                    ls_item=""; 
                } 
            } 
            else 
            { 
                if(typeid=="2") 
                { 
                    //从DataSet中直接导出XML数据并且写到HTTP输出流中 
                    resp.Write(ds.GetXml()); 
                } 
            } 
            //写缓冲区中的数据到HTTP头文档中 
            resp.End(); 
        }

下面是普通用法

 Response.Clear();
            Response.Buffer = true;
            Response.Charset = "utf-8";
            Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode("名称", System.Text.Encoding.UTF8) + ".xls");
            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);
            // repeater控件的ID
            this.Repeater1.RenderControl(oHtmlTextWriter);
            Response.Write(oStringWriter.ToString());
            Response.End();

导出另类样式的excel表

 

  //ExcelExporter.CreateExcel((DataSet)Session["dataset"], DateTime.Now.ToString() + ".xls", "application/ms-excel", this.Page);
            // ExcelExporter.CreateExcelO((DataSet)Session["dataset"], DateTime.Now.ToString() + ".xls", "application/ms-excel", this.Page);
            Response.Clear();
            Response.Buffer = true;
            //Response.AppendHeader("Content-Disposition", "attachment;filename=" + DateTime.Now.ToString()+".xls");
            // Response.AddHeader("Content-Disposition", "attachment;filename=" + DateTime.Now.ToString() + ".xls");

 

            Response.Charset = "utf-8";
            Response.ContentEncoding = System.Text.Encoding.UTF8;
            string names = DateTime.Now.ToString() + ".xls";
            //Response.Write(names);
            Response.AddHeader("content-disposition", "attachment;filename=" + names);

 

            Response.ContentType = "application/vnd.ms-excel";

 

            //System.IO.StreamWriter write = new System.IO.StreamWriter();
            System.IO.StringWriter write = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter html = new HtmlTextWriter(write);
            Repeater1.RenderControl(html);
            Response.Write(write.ToString());
            Response.Flush();

            Response.End();
