C# .Net輸出word和excel檔案方法和函數！

下面代碼是C# .net輸出word和excel檔案的公告函數，使用方法先建立gridview填充資料，然後用時copy如下函數到cs頁面，調用方法     OutExcel(GridviewName, "File name.xls");        OutWord(GridviewName, "File name.doc");
指定gridview的 名字和檔案名稱即可！

//輸出到excel的函數,可直接copy到 cs頁面
    private void OutExcel(GridView dg, string name)
    {
        dg.Visible = true;
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        name = "attachment;filename=" + name;
        Response.AppendHeader("Content-Disposition", name);
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
        Response.ContentType = "application/ms-excel";
        dg.EnableViewState = false;
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
        dg.RenderControl(oHtmlTextWriter);
        Response.Write(oStringWriter.ToString());
        Response.End();
    }
    //輸出到word的函數，可直接copy到 cs頁面
    private void OutWord(GridView dg, string name)
    {

        //string name="lessons.xls";
        dg.Visible = true;
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        name = "attachment;filename=" + name;
        Response.AppendHeader("Content-Disposition",  name);
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
        Response.ContentType = "application/ms-word";
        dg.EnableViewState = false;
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
        dg.RenderControl(oHtmlTextWriter);
        Response.Write(oStringWriter.ToString());
        Response.End();
    }
    //重載VerifyRenderingInServerForm方法，調用頁面必須加入否則會提示錯誤
   public override void VerifyRenderingInServerForm(Control control)
    {
    }
    //調用方法 OutWord(Student, "File name.doc");
    protected void Button1_Click(object sender, EventArgs e)
    {      
        OutWord(Student, "File name.doc");

    }
    //調用方法 OutExcel(Student, "File name.xls"); 
    protected void Button2_Click(object sender, EventArgs e)
    {
        OutExcel(Student, "File name.xls");       
    }
