1。

protected void toExcel_Click(object sender,EventArgs e)

{

ToExcel(parentList);

}

private void ToExcel(System.Web.UI.Control ctl)

{

Response.Charset="GB2312";

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();

}

2。导入excel写的太麻烦了，弹出窗口可以！用这个导入

Protected Sub toExcel_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs)

ToExcel1(tblResults)

End Sub

Sub ToExcel1(ByVal ctl As System.Web.UI.Control)

Response.Charset = "GB2312"

Response.AppendHeader("Content-Disposition", "attachment;filename=totalreport.xls")

Response.ContentEncoding = System.Text.Encoding.UTF8

Response.ContentType = "application/ms-excel"

ctl.Page.EnableViewState = False

Dim tw As System.IO.StringWriter = New System.IO.StringWriter()

Dim hw As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(tw)

ctl.RenderControl(hw)

Response.Write(tw.ToString())

Response.End()

End Sub

3.//将数据集导到excel 以 XLS 格式里

private void DataSetToExcelXls(DataSet ds)

{

用例说明

Random rd=new Random(int.Parse(DateTime.Now.ToString("MMddhhmmss")));

string strFileName =DateTime.Now.ToString("yyyyMMdd")+DateTime.Now.Hour+DateTime.Now.Minute+DateTime.Now.Second+txtBeginTime.Text.Trim()+txtFinishTime.Text.Trim()+rd.Next(999999).ToString()+ ".XLS";
