    2、ASP.NET MVC3中的使用Uploadify

           搭建ASP.NET MVC3解决方案如下图,其中使用到的Uploadify为3.1版本:

      1>、简单示例

          _Layout.cshtml代码:

    复制代码
    <!DOCTYPE html>
    <html>
    <head>
        <title>@ViewBag.Title</title>
        @RenderSection("Header")
    </head>
    
    <body>
        @RenderBody()
    </body>
    </html>
    复制代码

          Index.cshtml代码:

    复制代码
    @{
        ViewBag.Title = "Index";
        Layout = "~/Views/Shared/_Layout.cshtml";
    }
    @section Header{
        <link href="@Url.Content("~/Scripts/uploadify-v3.1/uploadify.css")" rel="stylesheet" type="text/css" />
        <script src="@Url.Content("~/Scripts/jquery-1.8.1.min.js")" type="text/javascript"></script>
        <script src="@Url.Content("~/Scripts/uploadify-v3.1/jquery.uploadify-3.1.min.js")" type="text/javascript"></script>
        <script type="text/javascript">
            $(function () {
                $('#file_upload').uploadify({
                    'swf'        : '@Url.Content("~/Scripts/uploadify-v3.1/uploadify.swf")',
                    'uploader'   : '/Home/Upload'
                });
            });
        </script>
        <style type="text/css">
            body
            {
                font-size: 12px;
            }
            .tip
            {
                height: 20px;
                border-bottom: 1px solid #CCC;
                margin-bottom: 10px;
            }
        </style>
    }
    <div class="tip">

    <input type="file" id="file_upload" name="file_upload" />
    复制代码

            HomeController.cs代码:

    复制代码
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.Mvc;
    
    using System.IO;
    
    namespace WebUI.Controllers
    {
        public class HomeController : Controller
        {
            //
            // GET: /Home/
    
            public ActionResult Index()
            {
                return View();
            }
    
            [AcceptVerbs(HttpVerbs.Post)]
            public JsonResult Upload(HttpPostedFileBase fileData)
            {
                if (fileData != null)
                {
                    try
                    {
                        // 文件上传后的保存路径
                        string filePath = Server.MapPath("~/Uploads/");
                        if (!Directory.Exists(filePath))
                        {
                            Directory.CreateDirectory(filePath);
                        }
                        string fileName = Path.GetFileName(fileData.FileName);// 原始文件名称
                        string fileExtension = Path.GetExtension(fileName); // 文件扩展名
                        string saveName = Guid.NewGuid().ToString() + fileExtension; // 保存文件名称
    
                        fileData.SaveAs(filePath + saveName);
    
                        return Json(new { Success = true, FileName = fileName, SaveName = saveName });
                    }
                    catch (Exception ex)
                    {
                        return Json(new { Success = false, Message = ex.Message }, JsonRequestBehavior.AllowGet);
                    }
                }
                else
                {
    
                    return Json(new { Success = false, Message = "请选择要上传的文件!" }, JsonRequestBehavior.AllowGet);
                }
            }
        }
    }
    复制代码

            上传效果图:

            2>、设置上传图片大小

            ASP.NET MVC默认情况下,允许上传的文件大小最大为4MB。因此在默认情况下,Uploadify也只能最大上传4MB大小的文件,超过范围则会IO报错提示无法上传。

            修改Web.config设置允许上传的最大文件大小:

    <system.web>
      <!--设置最大允许上传文件大小1G-->
      <httpRuntime maxRequestLength= "102400" executionTimeout= "60" />
    </system.web>

      修改最大上传文件大小后效果:

            3>、Uploadify常用属性设置

            auto:是否选择文件后自动上传,默认为true。
