使用GridLine導出Excel

Question

我有下面提到的代碼導出數據到excel

Response.Clear（）; Response.Buffer = true;

 Response.AddHeader("content-disposition", 
     "attachment;filename=GridViewExport.xls"); 
     Response.Charset = ""; 
     Response.ContentType = "application/vnd.ms-excel"; 
     System.IO.StringWriter sw = new System.IO.StringWriter(); 
     HtmlTextWriter hw = new HtmlTextWriter(sw); 
     Table tb = new Table(); 
     GridView gv=new GridView(); 

     tb.GridLines = gv.GridLines; 

     tb.BackColor = System.Drawing.Color.Transparent; 
     TableRow tr1 = new TableRow(); 
     TableCell cell1 = new TableCell(); 
     cell1.Controls.Add(BalanceSheetListControl2); 
     tr1.Cells.Add(cell1); 
     tb.Rows.Add(tr1); 
     tb.RenderControl(hw); 

     //style to format numbers to string 
     string style = @"<style> .textmode { mso-number-format:\@; backgroud-color:transparent !important; } </style>"; 
     Response.Write(style); 


     System.IO.StringReader writer = new System.IO.StringReader(sw.ToString()); 
     string s=string.Empty; 
     string readString = string.Empty; 
     bool StartFlag = false; 
     StringBuilder build = new StringBuilder(); 
     while((readString=writer.ReadLine())!=null) 
     { 
      // readString = writer.ReadLine().Trim(); 
      s = readString; 
      Regex search_string = new Regex("<div.*?>([^<]+)</div>"); 
      Match match = search_string.Match(s); 
      string section = match.Groups[1].Value.ToString(); 
      if (section.Trim()=="-") 
      { 
       s = s.Replace(">-<", "><div align='right'>-</div><"); 
       // s = s.Replace("-", "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;-&nbsp;"); 
      } 

      if (readString.Trim().Contains("main") || readString.Trim().Contains("column c")) 
      { 

       s=s+"</td><td>"; 
      } 

      build.Append(s); 

     } 

     Response.Output.Write(build.ToString()); 
     Response.Flush(); 
     Response.End(); 

我必須展示在Excel中網格線，我用下面的使用上的代碼後，代碼

 GridView gv=new GridView(); 
     tb.GridLines = gv.GridLines; 

Excel將只產生垂直網格線，我還需要水平線任何一個可以請幫助我如何實現這一目標？ 由於提前

參考我重視我的當前Excel形象

檢查這個代碼它爲我工作。

public static void ExportWithBorder(string fileName, GridView gv) 
    { 
     HttpContext.Current.Response.Clear(); 
     HttpContext.Current.Response.AddHeader(
      "content-disposition", string.Format("attachment; filename={0}", fileName)); 
     HttpContext.Current.Response.ContentType = "application/ms-excel";   

     using (StringWriter sw = new StringWriter()) 
     { 
      using (HtmlTextWriter htw = new HtmlTextWriter(sw)) 
      { 
       // Create a form to contain the grid 
       Table table = new Table(); 

       // add the header row to the table 
       if (gv.HeaderRow != null) 
       { 
        GridViewExportUtil.PrepareControlForExport(gv.HeaderRow); 
        gv.HeaderRow.Style.Add("border", "solid 1px #c1d8f1"); 
        table.Rows.Add(gv.HeaderRow); 
       } 

       // add each of the data rows to the table 
       foreach (GridViewRow row in gv.Rows) 
       { 
        GridViewExportUtil.PrepareControlForExport(row); 
        row.Style.Add("border", "solid 1px #c1d8f1"); 
        table.Rows.Add(row); 
       } 

       // add the footer row to the table 
       if (gv.FooterRow != null)

        gv.FooterRow.Style.Add("border", "solid 1px #c1d8f1"); 
        table.Rows.Add(gv.FooterRow); 
       } 

       // render the table into the htmlwriter      
       table.RenderControl(htw); 

       // render the htmlwriter into the response 
       HttpContext.Current.Response.Write(sw.ToString()); 
       HttpContext.Current.Response.End(); 
      } 
     } 
    }

      }

      { 
       control.Controls.Remove(current);

      } 
      else if (current is CheckBox) 
      { 
       control.Controls.Remove(current);

      } 
      else if (current is TextBox) 
      { 
       control.Controls.Remove(current); 
       control.Controls.AddAt(i, new LiteralControl((current as TextBox).Text)); 
      } 
      if (current.HasControls()) 
      {

      } 
     } 
    }
