Mvc图像上传无法正常工作

问题描述：

我的价值总是空值，

我尝试过：

控制器，

I got always null value for this,

What I have tried:

Controller,

if (itm.AttachmentModel.AttachmentFile != null)
               {
                   itm.AttachmentModel.AttachmentURL = string.Format("{0}.{1}", Guid.NewGuid().ToString(), itm.AttachmentModel.AttachmentFile.FileName.Split('.')[1]);
                   if (itm.AttachmentModel.AttachmentFile != null)
                   {

                       var path = Path.Combine(Server.MapPath("~/App_Data/Attachments/"), itm.AttachmentModel.AttachmentURL);
                       itm.AttachmentModel.AttachmentFile.SaveAs(path);
                   }
               }

查看，

View,

<input type="hidden" value="" name="..."><input type="file" name="AttachmentFile">

模态，

Modal,

public HttpPostedFileBase AttachmentFile { get; set; }
    public string AttachmentURL
    {
        get
        {
            return attachment;
        }

        set
        {
            attachment = value;
        }
    }

    public string Attachment
    {
        get
        {
            return attachment;
        }

        set
        {
            attachment = value;
        }
    }

您好，我正在分享一个示例，以便在帖子上获取图像（文件）方法：

[HttpPost]

public ActionResult GetImage（HttpPostedFileBase文件）

{

//你可以把你现有的保存代码放在这里

if（file！= null&& file.ContentLength > 0）

{

//用文件做你想做的任何事情

}

}

希望它对你有所帮助。

Hello, I am sharing one example for get the image(file) on post method:

[HttpPost]
public ActionResult GetImage(HttpPostedFileBase file)
{
//you can put your existing save code here
if (file != null && file.ContentLength > 0)
{
//do whatever you want with the file
}
}

Hope it's helpful for you.
