MVC upload image MVC上传图片的例子

直接上MVC上传图片的代码了。

View :

<% using (Html.BeginForm(Html.ViewContext.RouteData.Values["action"].ToString(), Html.ViewContext.RouteData.Values["controller"].ToString(), FormMethod.Post, new { enctype = "multipart/form-data" }))

       { %>

         

        <div>

        <table>

            <tr>

                <td>

                    文章图片

                </td>

                <td>                    

                  <input id="txtUploadFile" type="file" name="file" accept="image/gif" onchange="return FilterFileType();"  style="width:350px;" />

                </td>

                </tr>

            <tr>

                <td>

                </td>

                <td>

                

                    <input type="submit" onclick="$('#IsPublish').attr('value','True');" value="保存并发布" />

                </td>

            </tr>

        </table>

    </div>

    

        <script type="text/javascript">

         function FilterFileType() {

            var fullName = document.getElementById("txtUploadFile").value;           

            if (fullName != "")   

              {   

                  var   s,ss;

                  var s = fullName;   

                  ss=   s.substr(s.length-4,s.length);   

                  if   (ss!=".gif"   &&   ss!=".jpg"   &&   ss!=".bmp")   

                  {   

                      alert("图片文件上传只支持.gif   .jpg   .bmp");   

                      return   (false);   

                  }

              }



         }     

     </script>

            

    <% } %>

 

 

Controller:

        [AcceptVerbs(HttpVerbs.Post)]
        [ValidateInput(false)]
        public ActionResult Create(HttpPostedFileBase file)
        {
            
                try
                {
                    if (file != null)
                    {
                        var fileName = Path.Combine(Request.MapPath("~/App_Data/Image"), Path.GetFileName(file.FileName));
                        file.SaveAs(fileName);//保存Img图片
                       }
                 }
                catch(Exception e)
                {
                    
                }
               return View();
               // If we got this far, something failed, redisplay form
            
        }
