/// <summary>
    /// 动态创建Grid
    /// </summary>
    /// <returns></returns>
    private GridView CreateGrid()
    {
        GridView gdvGrid = new GridView();
        gdvGrid.AutoGenerateColumns = false;
        BoundField bf1 = new BoundField();
        bf1 .HeaderText = "采购员名称";
        bf1 .DataField = "采购员名称";
        gdvGrid.Columns.Add(bf1 );
        return gdvGrid;
    }
    /// <summary>
    /// 导出Excel方法
    /// </summary>
    /// <param name="ctl"></param>
    private void ToExcel(System.Web.UI.Control ctl)
    {
        Response.Charset = "UTF-8";
        Response.AppendHeader("Content-Disposition", "attachment;filename=Excel.xls");
        Response.ContentEncoding = System.Text.Encoding.UTF8;
        Response.ContentType = "application/ms-excel";        ctl.Page.EnableViewState = false;
        System.IO.StringWriter tw = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(tw);        ctl.RenderControl(hw);        Response.Write(tw.ToString());
        Response.End();
    }    /// <summary>
    /// 绑定动态表格及调用ToExcel方法
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void btnToExcel_Click(object sender, EventArgs e)
    {
        GridView gdvGrid = CreateGrid();
        divshow.Controls.Add(gdvGrid);
        DataSet ds = new DataSet();
        ds = GetListFromProc(); 
        gdvGrid.DataSource = ds.Tables["NoticeInvoiceDetail_DS1"];
        gdvGrid.DataBind();        Control table = gdvGrid.Controls[gdvGrid.Controls.Count - 1];
        ToExcel(table);        divshow.Controls.Clear();

/// <summary>
  /// 导出Excel方法
  /// </summary>
  /// <param name="ctl"></param>
  private void ToExcel(System.Web.UI.Control ctl)
  {
  Response.Charset = "UTF-8";
  Response.AppendHeader("Content-Disposition", "attachment;filename=Excel.xls");

  System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(tw);  ctl.RenderControl(hw);  Response.Write(tw.ToString());

  }
改成[code=C#]

    dtTest.Dispose();
   
    excel.Visible=true;
    
   }
   catch (System.Exception e)
   {
    throw e;
   }
   finally
   {
    excelCell=null;
    xBk=null;
    xSt=null;
    excel=null;  
    GC.Collect();
   }
   
  }[code]或者找一个方法替换一下
传入Gridview 就行了。
