Answer 1

       private void Export(string FileType, string FileName)
        {
            Response.Charset = "GB2312";
            Response.ContentEncoding = System.Text.Encoding.UTF7;
            Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
            Response.ContentType = FileType;
            this.EnableViewState = false;
            StringWriter tw = new StringWriter();
            HtmlTextWriter hw = new HtmlTextWriter(tw);
            datagrid1.RenderControl(hw);
            Response.Write(tw.ToString());
            Response.End();
        }
        public override void VerifyRenderingInServerForm(Control control)
        {
        }        protected void Button1_Click(object sender, EventArgs e)
        {
            Export("application/ms-excel", "结果.xls");        }需要导入
using System.IO;
using System.Text;

Answer 2

原来写的代码//该方法实现将数据导入到Excel文件中，其中的DataTable dt就是你需要将数据写入到Excel中的数据；
        static public void ExportExcel(DataTable dt, StreamWriter w)
        {
            try
            {
                for (int i = 0; i < dt.Columns.Count; i++)
                {
                    w.Write(dt.Columns[i]);
                    w.Write(' ');
                }
                w.Write(" ");                object[] values = new object[dt.Columns.Count];
                foreach (DataRow dr in dt.Rows)
                {
                    values = dr.ItemArray;
                    for (int i = 0; i < dt.Columns.Count; i++)
                    {
                        w.Write(values[i]);
                        w.Write(' ');
                    }
                    w.Write(" ");
                }
                w.Flush();
                w.Close();
            }
            catch
            {
                w.Close();
            }
        }
