网页中的数据导出问题(word文档等格式)

  方法一：
 

HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + filename);

HttpContext.Current.Response.Charset = "UTF-8";

HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;

  HttpContext.Current.Response.ContentType = filetype;

 //HttpContext.Current.Response.ContentType = "application/ms-excel";//image/JPEG;text/HTML;image/GIF;vnd.ms-excel/msword

HttpContext.Current.Response.Buffer = true

System.IO.StringWriter tw = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);

gv.RenderControl(hw);



HttpContext.Current.Response.Write(tw.ToString());

HttpContext.Current.Response.End();

  方法二：
 

private   void   ExportWord_Click(object   sender,   System.EventArgs   e)  

  {  

  try  

  {  

  string   savepath   =   "";  

  FolderBrowserDialog   folderBrowserDialog1   =   new   FolderBrowserDialog();  

  if   (folderBrowserDialog1.ShowDialog()   ==   DialogResult.OK)    

  {  

  savepath   =   folderBrowserDialog1.SelectedPath;  

  }  

   

  Object   Nothing=System.Reflection.Missing.Value;  

  object   filename   =   savepath   +   "/"   +   StoreNum.Text   +   "库存报表";  

  Word.Application   WordApp=new   Word.ApplicationClass();  

  Word.Document   WordDoc=WordApp.Documents.Add(ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing);  

   

  WordDoc.Paragraphs.First.Range.Text   =   "库存报表       [共有："   +   storedt.Rows.Count.ToString()   +   "本书]";  

  WordDoc.Paragraphs.First.Alignment   =   Word.WdParagraphAlignment.wdAlignParagraphCenter;  

   

  Word.Table   table=WordDoc.Tables.Add(WordApp.Selection.Range,storedt.Rows.Count+1,6,ref   Nothing,ref   Nothing);  

  table.Cell(1,1).Range.Text="ISBN号";  

  table.Cell(1,2).Range.Text="书名";  

  table.Cell(1,3).Range.Text="总库存";  

  table.Cell(1,4).Range.Text="借书库存";  

  table.Cell(1,5).Range.Text="可借数量";  

  table.Cell(1,6).Range.Text="已借数量";  

   

  for   (   int   i=0;i<storedt.Rows.Count;i++   )  

  {  

  table.Cell(i+2,1).Range.Text   =   storedt.Rows[i]["Book_ISBN"].ToString();  

  table.Cell(i+2,2).Range.Text   =   storedt.Rows[i]["Book_Name"].ToString();  

  table.Cell(i+2,3).Range.Text   =   storedt.Rows[i]["Store_Num"].ToString();  

  table.Cell(i+2,4).Range.Text   =   storedt.Rows[i]["CanBorrow_Num"].ToString();  

  table.Cell(i+2,5).Range.Text   =   storedt.Rows[i]["InShop_Num"].ToString();  

  table.Cell(i+2,6).Range.Text   =   storedt.Rows[i]["OutShop_Num"].ToString();  

  }  

   

  WordDoc.SaveAs(ref   filename,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing,ref   Nothing);  

  WordDoc.Close(ref   Nothing,   ref   Nothing,   ref   Nothing);  

  WordApp.Quit(ref   Nothing,   ref   Nothing,   ref   Nothing);  

  parent.statusBar1.Panels[0].Text   =   "操作提示：库存报表导出成功";  

  }  

  catch  

  {  

  parent.statusBar1.Panels[0].Text   =   "操作提示：库存报表导出失败";  

  }  

  }  

   

  注意要引用Interop.Word.dll，并且在机器上安装Word2002，否则导出将失败
