单文件上传-asp.net mvc版本
1.web.config
appSettings配置节
<add key="UploadFileUrl" value="http://file.mydomain.com/" />
<add key="UploadFilePath" value="E:\file.mydomain.com\imagefiles\"/>
2.Controller
//FileController.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Ajax;
using System.Drawing;
using System.Configuration;
namespace MyDomain.Controllers
{
public class FileController : Controller
{
public ActionResult Up()
{
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Up(HttpPostedFileBase postedFile)
{
if (postedFile != null)
{
string dir = ConfigurationManager.AppSettings["UploadFilePath"];//Server.MapPath("/imagefiles/");
string rooturl = System.Configuration.ConfigurationManager.AppSettings["rooturl"];
string guid = System.Guid.NewGuid().ToString();
string ext = postedFile.FileName.Substring(postedFile.FileName.LastIndexOf("."));
string filename = dir + guid + ext;
string url = rooturl + "imagefiles/" + guid + ext;
postedFile.SaveAs(filename);
ViewData["url"] = url;
}
else
{
ViewData["msg"] = "posted file is null.";
ViewData["url"] = "";
}
return View();
}
}
}
3.View
File/Up.aspx
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<base target="_self" />
</head>
<body>
<div>
<h2>Upload File</h2>
<ul id="form_content">
<li>
You may upload image file,such as JPEG,BMP,GIF,PNG.
</li>
<li>
<% using (Html.BeginForm("Up", "File", FormMethod.Post, new { id = "uploadForm", enctype = "multipart/form-data" }))
{
%>
<table width="98%" >
<tr><td width="10%">File:</td><td><input type="file" name="postedFile" style="width:80%" /> <input type="submit" value="Upload" /></td></tr>
<tr><td>Result:</td><td ><%=ViewData["msg"] %><span id="result" runat="server"><%=ViewData["url"] %></span></td></tr>
<tr><td colspan="2" align="center"><input type="button" value="Close" onclick="closeWindow()" /></td></tr>
</table>
<%} %>
</li>
</ul>
<div id="footer">
</div>
</div>
</body>
</html>
4.在页面中使用以上文件上传页面
<script type="text/javascript">
function uploadFile(obj) {
var url = "/file/up";
var result = window.showModalDialog(url + "?R=" + Math.random());
if (result != undefined && result != "") {
var inputObj = document.getElementById(obj);
inputObj.value = result;
}
}
function showPic(obj) {
var inputObj = document.getElementById(obj);
var url = inputObj.value;
if(url == "") return;
window.open(url);
}
</script>
<input type="text" name="image1" /> <a href='javascript:void(0)' onclick="uploadFile('image1')">Up</a> | <a href='javascript:void(0)' onclick="showPic('image1')">View</a>
当然了，也可以把这个改写成一个控件，来调用，就跟asp.net那个版本一样。
