asp.net mvc V与C图片的交互方式罗列

1.上传图片

  a.cshtml

<div class="container-fluid">   
 @using (Html.BeginForm("Add", "Dodate", FormMethod.Post, new { enctype = "multipart/form-data" }))
    { 
        @Html.AntiForgeryToken("doutu")
        @Html.ValidationSummary(true)
        @Html.HiddenFor(m => m.id)
        <div class="control-group">
                <label class="control-label">
                    上传原型图:</label>
                <div class="controls">
                    <input type="file" id="file" name="file" required />
                </div>
            </div>
   }
</div>    

 b.controller

   　　　[HttpPost]
        [ValidateInput(true)]
        [ValidateAntiForgeryToken(Salt = "doutu")]
        public ActionResult Add()
        {
            HttpFileCollectionBase httpFiles = HttpContext.Request.Files;
            HttpPostedFileBase file = httpFiles[0];
            string pathName = string.Format("/Image/{0}", DateTime.Now.ToString("yyyyMMddhhmmssfff") + file.FileName);
            string filename = Server.MapPath("~/" + pathName);
            file.SaveAs(filename);
            return RedirectToAction("Index");
        }

MVC 里面 View层如何获取Controller 层的图片，以显示在界面上，上代码

访问这个路径就可以了。

[HttpGet]

   
  　　　[HttpGet]
　　　　public ActionResult TestImage(string words1)
        {
            string imageSrc = HttpContext.Server.MapPath("~/Image/dout1/2.png");
            byte[] image = Utils.DrawImage(imageSrc, words1);
            return File(image, "image/jpeg");
        }

[HttpPost]

     　　[HttpPost]
        [ValidateInput(true)]
        [ValidateAntiForgeryToken()]
        public ActionResult post(DSet dSet)
        {
    　　　　　string imageSrc = HttpContext.Server.MapPath("~/" + dSet.sourceSrc);
            byte[] image = Utils.DrawImage(imageSrc);
            ViewBag.image = image;
            return View(dSet);
　　　　}

post 的页面对应如下

　　　　　　<div style="text-align: center">
                @{
                    var base64 = Convert.ToBase64String(ViewBag.image);
                    var imgSrc = String.Format("data:image/jpeg;base64,{0}", base64);
                }
                <img id="image" style="max-width: 100%" src="@imgSrc" />
            </div>
