如何上传文件在MVC+Umbraco 7

Question

我是MVC的新手，需要帮助上传文件，我正在使用umbraco。7.2.1我正在尝试用带有附件的邮件发送邮件以下是我的相同代码。部分视图===>名称联系

 using (Html.BeginUmbracoForm<ContactVController>("HandleContactSubmit"))   
    {
       @Html.LabelFor(model => model.Name)<br />
       @Html.EditorFor(model => model.Name)<br />
       @Html.ValidationMessageFor(model => model.Name)<br />
       @Html.LabelFor(model => model.Email)<br />
       @Html.EditorFor(model => model.Email)<br />
       @Html.ValidationMessageFor(model => model.Email)<br />
          <input type="file" name="file" id="file" />
        <p>
           <input type="submit" value="Submit" />
       </p>
    }

型号

public class ContactVModel  
{
    [Required]
    public string Name { get; set; }
    [Required]
    [RegularExpression(@"[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?")]
    public string Email { get; set; }
    [Required]
    public string Message { get; set; }
    public HttpPostedFileBase attachment { get; set; }
}

控制器

public class ContactVController : SurfaceController
    {
    [HttpPost]
    public ActionResult HandleContactSubmit(ContactVModel model)
        {
,.......... ...... ....
  ,.......... ...... ....  
    MailBody + = model.Name ;
MailBody + = model.Email;
SendMail( MailBody )
}

但我不知道访问模式。附件，我如何发送带有附件的邮件（上传的文件）（因为我可以访问姓名、电子邮件等）我已经参考了以下帖子，但我无法访问附件

MVC 4 Razor文件上传

但我无法识别

Answer 1

更改的输入

<input type="file" name="file" id="file" />

至

<input type="file" name="attachment" id="attachment" /> 

因此，模型中的属性与输入字段匹配。

我目前正在使用以下内容：

In the cshtml file:
@Html.UploadFor(model=> model.Attachment)
static public class HtmlExtensions
{
    public static IHtmlString UploadFor<TSource, TResult>(this HtmlHelper<TSource> html, Expression<Func<TSource, TResult>> propertyExpression)
    {
        var memberName = Reflection.GetPropertyName(propertyExpression);
        return new HtmlString($"<input type="file" name="{memberName}" id="{memberName}">");
    }
}
class Reflection
{
    public static string GetPropertyName<TSource, TResult>(Expression<Func<TSource, TResult>> propertyExpression)
    {
        return (propertyExpression.Body as MemberExpression).Member.Name;
    }
}
