易采站长站为您分析C#简单实现文件上传功能,利用MVC+EF+LigerUI 实现的upload上传功能,感兴趣的小伙伴们可以参考一下
最近项目上的一个上传文件功能,项目是MVC+EF+LigerUI 来做的,贴出来大家一起分享下
1、页面需要引用这个JS 和 CSS
<script type="text/javascript" src="/Content/uploadify/jquery.uploadify.min.js"></script>
<link href="/Content/uploadify/uploadify.css" type="text/css" rel="stylesheet" />
2、页面添加Upload.ashx
3、代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
using System.Web.Security;
namespace AL.Web {
/// <summary>
/// Upload 的摘要说明
/// </summary>
public class Upload : IHttpHandler {
public void ProcessRequest(HttpContext context) {
context.Response.ContentType = "text/plain";
//context.Response.Write("Hello World");
string r = "";
//此处有时候穿过来的sn后面还有一些乱七八糟的字符,没研究什么意思,就判断一下,截取一下就完事了,小项目~
string sn = context.Request.QueryString["sn"];
if (sn != null && sn.Length > 14) sn = sn.Substring(0, 14);
if (context.User.Identity.IsAuthenticated == false) {
// 未登录用户
}
try {
//获取上传的文件数据
HttpPostedFile file = context.Request.Files["Filedata"];
string fileName = file.FileName;
string fileType = Path.GetExtension(fileName).ToLower();
//由于不同浏览器取出的FileName不同(有的是文件绝对路径,有的是只有文件名),故要进行处理
if (fileName.IndexOf(' ') > -1) {
fileName = fileName.Substring(fileName.LastIndexOf(' ') + 1);
} else if (fileName.IndexOf('/') > -1) {
fileName = fileName.Substring(fileName.LastIndexOf('/') + 1);
}
//上传的目录
string uploadDir = "~/Content/uploadfile/TMP/" + System.DateTime.Now.ToString("yyyyMM") + "/";
//上传的路径
//生成年月文件夹及日文件夹
if (Directory.Exists(context.Server.MapPath(uploadDir)) == false) {
Directory.CreateDirectory(context.Server.MapPath(uploadDir));
}
if (Directory.Exists(context.Server.MapPath(uploadDir + System.DateTime.Now.ToString("dd") + "/")) == false) {
Directory.CreateDirectory(context.Server.MapPath(uploadDir + System.DateTime.Now.ToString("dd") + "/"));
}
uploadDir = uploadDir + System.DateTime.Now.ToString("dd") + "/";
string uploadPath = uploadDir + FormsAuthentication.HashPass
