市委组织部项目--word上传，下载，预览，删除

需求：市委组织部考核项目，既然是考核项目就会有很多考核标准要求等，而且各个下属单位对于被考核指标的结果需要上传。这些过程都是通过文档实现的。也就是需要word文档的上传，下载，预览等功能。

Word上传：

后台代码：

<span style="font-family:KaiTi_GB2312;font-size:24px;">        /// <summary>/// word上传/// </summary>/// <param name="sender"></param>/// <param name="e"></param>protected void btnUpWord_Click(object sender, EventArgs e){string newName = "";string flex = "";string wjlj = "";//事务开始——using (TransactionScope tx = new TransactionScope()){ try{if (Request.Files.Count > 0){Random ro = new Random();if (FileUpload2.FileName != ""){                       //文档全称string filename = Path.GetFileName(FileUpload2.FileName).Trim ();//无后缀名的文档名称string filemainname = (Path.GetFileNameWithoutExtension(FileUpload2.FileName)).Trim ();//文档后缀名flex = (Path.GetExtension(FileUpload2.FileName)).Trim ();if (flex == ".doc" || flex == ".docx"){//string stro = ro.Next(100, 1000000).ToString();//string stro = DateTime.Now.ToString("yyyyMMdd");//newName = DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + DateTime.Now.Millisecond.ToString() + stro;           //上传后添加数据在数据库中WordEntity enWord = new WordEntity();//enWord.WordAddress= Server.MapPath("UpLoadWord/") + FileUpload2.FileName;wjlj = "UpLoadWord/" + filemainname + newName + flex;enWord.WordAddress = wjlj;enWord.WordName = filename;DateTime now = DateTime.Now;enWord.StrDate = DateTime.Now.ToString("yyyy-MM-dd");enWord.StrYear = now.Year.ToString();//enWord.UnitName=Session["UserName"].ToString ();enWord.UnitName = "hejingyuan";WordBLL wordBll = new WordBLL();//判断此单位是否已经上传过这个文档了,参数，文档名称和提交单位bool isExist = wordBll.Exists(filename);if (isExist == false){bool flag = wordBll.Add(enWord);if (flag == false){MessageBox.Show(this, "word上传失败，请联系管理员！");throw new Exception();//return;}else{ //保有存文件到目录下  //FileUpload2.PostedFile.SaveAs(Server.MapPath("UpLoadWord/") + newName + flex);FileUpload2.PostedFile.SaveAs(Server.MapPath("UpLoadWord/") + newName + filename);//wjlj = "UpLoadWord/" + filemainname + newName + flex;Response.Write("<script>alert('保存成功');location.replace(location.href)</script>");}}else{//MessageBox.Show(this, "word上传失败，此文档已经存在！");//File.Delete(Server.MapPath("UpLoadWord/") + FileUpload2.FileName);Response.Write("<script>alert('word上传失败，此文档已经存在！');location.replace(location.href)</script>");//return;}}else {System.Web.HttpContext.Current.Response.Write("<script language='javascript'>alert('导入文件格式不对,导入文件必须为Word文件!');;window.location.href='" + System.Web.HttpContext.Current.Request.ServerVariables["HTTP_REFERER"] + "'</script>");System.Web.HttpContext.Current.Response.End();}}}//string sql = string.Format("insert into zl(xh, wdmc, wdlj)values ('{0}','{1}','{2}')", Guid.NewGuid().ToString(), wdmc, wjlj);//执行SQL语句,省略.....              tx.Complete();}catch (Exception){File.Delete(Server.MapPath("UpLoadWord/") + FileUpload2.FileName);Response.Write("<script>alert('保存错误,请联系管理员！');location.replace(location.href)</script>");}finally{//释放资源tx.Dispose();}}}

Word预览，下载，删除，查询。

年份：根据年份进行筛选信息。文件名:模糊查询

预览效果：

总结：

以上只是对word上传，预览，下载，删除操作的代码罗列，整理出来方便以后查看，积累经验，其中的一些知识点会在后续的博客中继续总结！其中有一点需要大家注意就是存放在数据库中的文档地址字段“\”符号，因为“\”符号加一些字母通常会代表一些含义，固需要转义！
