简单的有两种方式下载，一种是流下载，一种是Writefile下载。以下是使用Writefile下载。

代码：

复制代码 代码如下:
protected voID linkbutton1_Click(object sender,EventArgs e)
        {
            try
            {
                //Writefile实现下载(word)
                string filename = "qingPingguo.docx";//客户端保存的文件名
                string filePath = Server.MapPath("~\\excel\\" + tb1.Text);//路径

                fileInfo fileInfo = new fileInfo(filePath);
                Response.Clear();
                Response.ClearContent();
                Response.Clearheaders();
                response.addheader("Content-disposition","attachment;filename=" + filename);
                response.addheader("Content-Length",fileInfo.Length.ToString());
                response.addheader("Content-transfer-encoding","binary");
                Response.ContentType = "application/octet-stream";
                Response.ContentEnCoding = System.Text.EnCoding.GetEnCoding("gb2312");
                Response.Writefile(fileInfo.Fullname);
                Response.Flush();
                Response.End();
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message);
            }

            /*************以下为流方式下载****************/
            //string filename = "aaa.txt";//客户端保存的文件名
            //string filePath = Server.MapPath("DownLoad/aaa.txt");//路径

            ////以字符流的形式下载文件
            //fileStream fs = new fileStream(filePath,fileMode.Open);
            //byte[] bytes = new byte[(int)fs.Length];
            //fs.Read(bytes,bytes.Length);
            //fs.Close();
            //Response.ContentType = "application/octet-stream";
            ////通知浏览器下载文件而不是打开
            //response.addheader("Content-disposition","attachment;  filename=" + httpUtility.UrlEncode(filename,System.Text.EnCoding.UTF8));
            //Response.BinaryWrite(bytes);
            //Response.Flush();
            //Response.End();

        }
