这里有段处理代码，可以看看，导出为word和excel
protected void Button2_Click(object sender, EventArgs e)
{
SaveTo("application/ms-word", "演示.doc");
}

protected void Button1_Click(object sender, EventArgs e)
{
SaveTo("application/ms-excel", "演示.xls");
}

protected void SaveTo(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.AppendHeader("Content-Disposition",
"attachment;filename=" + HttpUtility.UrlEncode(
FileName, System.Text.Encoding.UTF8).ToString());
Response.ContentType = FileType;

//设置页面的EnableEventValidation="false"
this.EnableViewState = false;

System.IO.StringWriter tw = new System.IO.StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
}

//重写基类的方法（这个一定要写，不然会报错）
public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control);
}

<head runat="server">
//打印控制
<style media="print" type="text/css">
.Noprint{display:none;}
.PageNext{page-break-after:always;}
td,table{background:display:none;}
</style>
</head>

利用WebBrowser！
<object id="WebBrowser" height="0" width="0" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"></object>
<input id="button1" onclick="document.all.WebBrowser.ExecWB(6,1);"type="button"value="打印"class="Noprint">
<input id="button2" onclick="document.all.WebBrowser.ExecWB(6,6);"type="button"value="直接打印"class="Noprint">
<input id="button3" onclick="document.all.WebBrowser.ExecWB(8,1);"type="button"value="页面设置" class="Noprint">
<input id="button4" onclick="document.all.WebBrowser.ExecWB(7,1);"type="button"value="打印预览"class="Noprint">
<input id="button5" type="button" value="关闭窗口" onclick="javascript:window.close()"class="Noprint">
