[整理]匯出excel檔案的代碼

方法1.假定你要將目標頁面匯出為excel,只需要將上面的代碼添加到Page_load()裡.這行代碼主要的作用是設定http協議頭的參數,指明傳輸的網頁內容為Excel型的附件.

HttpContext.Current.Response.AppendHeader("Content-Disposition","attachment;filename=gcmx"+System.DateTime.Today.ToShortDateString()+".xls");
HttpContext.Current.Response.ContentType ="application/ms-excel";//image/JPEG;text/HTML;image/GIF;vnd.ms-excel/msword   

方法2：

DataGrid dgdata = new DataGrid();
dgdata.AllowPaging = false;
dgdata.DataSource=ds.Tables[0].DefaultView;
dgdata.DataBind();
string filename = System.DateTime.Now.ToString("yyyyMMddHHmmssff")+".xls";
Response.Clear();
Response.Buffer = true;
Response.Charset = "GB2312";
Response.AppendHeader("Content-Disposition","attachment;filename="+filename.Trim()); //定義輸出檔案和檔案名稱 
Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");//設定輸出資料流為簡體中文 
Response.ContentType = "application/ms-excel";//設定輸出檔案類型為excel檔案。
dgdata.EnableViewState = false; 
//System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true); 
//System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad); 
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(); 
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter); 
dgdata.RenderControl(oHtmlTextWriter); 
Response.Write(oStringWriter.ToString());                
Response.End();
