利用OWC组件生成EXCEL表(c#)

 

 

                Microsoft.Office.Interop.Owc11.SpreadsheetClass  oSheet= new SpreadsheetClass( );
                XmlDocument  xmlDoc = new XmlDocument( );
                xmlDoc.Load(Server.MapPath("./Reports/")+"abc.xml");
                string strXml =xmlDoc.DocumentElement.OuterXml;
                oSheet.XMLData = strXml; 
                
                oSheet.Cells[2,12]=DateTime.Now.ToString("yyyyMMdd");//制表日期                
                int i=4;
                if (Session["datatable"] != null)
                {
                    DataTable dt=    (System.Data.DataTable)Session["datatable"];
                    for(int j=0;j<dt.Rows.Count;j++)
                    {
                        oSheet.Cells[i,1] = dt.Rows[j][1].ToString();
                        oSheet.Cells[i,2] = dt.Rows[j][2].ToString();
                        oSheet.Cells[i,3] = dt.Rows[j][3].ToString();                        
               i++;                
                    }

                }
                oSheet.get_Range(oSheet.Cells[4,1], oSheet.Cells[i-1,3]).Borders.set_LineStyle(XlLineStyle.xlContinuous);
                oSheet.get_Range(oSheet.Cells[4,1], oSheet.Cells[i-1,3]).Font.set_Size(10);
string desFileName="abc"+System.DateTime.Now.ToString("yyMMddHHmmssff")+".xls";
                string desPathFileName=Server.MapPath("../ReportDocs/")+desFileName;            
            
                //輸出整理後的文件
                oSheet.Export(desPathFileName, Microsoft.Office.Interop.Owc11.SheetExportActionEnum.ssExportActionNone, Microsoft.Office.Interop.Owc11.SheetExportFormat.ssExportXMLSpreadsheet);

                string path = desPathFileName;
                System.IO.FileInfo file = new System.IO.FileInfo(path);  //以下載的方式顯示文件
                Response.Clear();
                //    Response.Charset="GB2312";
                Response.ContentEncoding=System.Text.Encoding.UTF8;
                // 指定默認文件名
                Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(file.Name));
                // 指定文件大小
                Response.AddHeader("Content-Length", file.Length.ToString());
                // 下載方式
                Response.ContentType = "application/ms-excel";
                // 把文件流傳送到Client端
                Response.WriteFile(file.FullName);
                file = null;
                Response.End();
