MVC上传文件功能

MVC上传文件功能

在提交数据的Controller控制器里：

        public ActionResult SavePCNRequest(提交的Model类型 model, HttpPostedFileBase Attachment1)
        {
        //创建上传的路径
       string PathValue = Server.MapPath("~/UploadFiles/PCN/" + model.RequestID + "/");
                if (false == Directory.Exists(PathValue))
                {
                    Directory.CreateDirectory(PathValue);
                }
        //获取是否有上传附件，有则进行上传
        {
        if (Attachment1 != null)
         {
          var fileName = Path.GetFileName(Attachment1.FileName);
          if (fileName != "System.Web.HttpPostedFileWrapper")
           {
            model.Attachment1 = fileName;
            }
            //根据上传文件名生成新路径
           var path = Path.Combine(PathValue, fileName);
           Attachment1.SaveAs(path);
         }
         }

前端HTML页面代码:

<div class="form-group">
        @Html.Label("ECN File", new { @class = "col-md-2 control-label" }) 
    <div class="col-md-10">
        <div class="col-md-8">
            <input type="file" id="Attachment1" name="Attachment1"  />
        </div>
        <div id="AddFileTemp1" class="col-md-4">
        </div>
    </div>
</div>
