Question

我使用Jquery Ajax Form Plugin上传文件。代码：

AuthorViewModel

public class AuthorViewModel
{
    public int Id { get; set; }

    [Required(ErrorMessage = "{0} alanı boş bırakılmamalıdır!")]
    [Display(Name = "Yazar Adı")]
    public string Name { get; set; }

    [Display(Name = "Kısa Özgeçmiş")]
    public string Description { get; set; }

    [Display(Name = "E-Posta")]
    public string Email { get; set; }

    public string OrginalImageUrl { get; set; }

    public string SmallImageUrl { get; set; }
}

表格

@using (Html.BeginForm("_AddAuthor", "Authors", FormMethod.Post, new { id = "form_author", enctype = "multipart/form-data" }))
{
    <div class="editor-label">
        <input type="file" name="file" id="file" />
    </div>
    <div class="editor-label">
        @Html.LabelFor(model => model.Name)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Name)
    </div>
    <div class="editor-field">
        @Html.ValidationMessageFor(model => model.Name)
    </div>

    ...

    <div class="submit-field">
        <input type="submit" value="Ekle" class="button_gray" />
    </div>
}

脚本

<script>
$(function () {
    $('#form_author').ajaxForm({
        beforeSubmit: ShowRequest,
        success: SubmitSuccesful,
        error: AjaxError
    });
});

function ShowRequest(formData, jqForm, options) {
    $(".loading_container img").show();
}

function AjaxError() {
    alert("An AJAX error occured.");
}

function SubmitSuccesful(result, statusText) {
    // Veritabanı işlemleri başarılı ise Index sayfasına
    // geri dön, değilse partial-view sayfasını yenile
    if (result.url) {
        window.location.href = result.url;
    } else {
        $(".authors_content_container").html(result);
    }
}
</script>

控制器

[HttpPost]
public ActionResult _AddAuthor(AuthorViewModel viewModel, HttpPostedFileBase file)
{
    ...
    viewModel.OrginalImageUrl = file.FileName;
    ...
}

以上代码可以正常使用

问题

如您所见，我从ViewModel发布文件。有没有办法将HttpPostedFileBase file属性添加到ViewModel并将其绑定到视图中的viewModel，并将其发布到ViewModel中的控制器？

我希望，我可以解释一下。

编辑：

此代码工作正常。我不想分别发布post，viewModel和HttpPostedFile。我想要这样的事情:(如果可能的话。）

模型

public class AuthorViewModel
{
    public int Id { get; set; }

    [Required(ErrorMessage = "{0} alanı boş bırakılmamalıdır!")]
    [Display(Name = "Yazar Adı")]

    HttpPostedFileBase file{ get; set; }
    ...
}

控制器

[HttpPost]
public ActionResult _AddAuthor(AuthorViewModel viewModel)
{
    var file = viewModel.file;
    ...
}

感谢。

是的，你可以添加AliRızaAdıyahşi。

这是属性：

public HttpPostedFileBase File { get; set; }

现在你的形式应该添加enctype，因为小小马说：

@using (Html.BeginForm("_AddAuthor", "Authors", FormMethod.Post, new { id = "form_author", enctype="multipart/form-data" }))
{
    <div class="editor-label">
        <input type="file" name="file" id="file" />
    </div>
    <div class="editor-label">
        @Html.LabelFor(model => model.Name)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Name)
    </div>
    <div class="editor-field">
        @Html.ValidationMessageFor(model => model.Name)
    </div>

    ...

    <div class="submit-field">
        <input type="submit" value="Ekle" class="button_gray" />
    </div>
}

关于你的控制器动作：

[HttpPost]
public ActionResult _AddAuthor(AuthorViewModel viewModel, HttpPostedFileBase file)
{
    if(file!=null)
    {
        viewModel.File=file; //Binding your file to viewModel property
    }
    //Now you can check for model state is valid or not.
    if(ModelState.IsValid)
    {
        //do something
    }
    else
    {
        return View(viewModel);
    }
}

希望它有所帮助。这是你需要的吗？

修改

没有其他事可做。它自动绑定到viewModel。

[HttpPost] public ActionResult _AddAuthor(AuthorViewModel viewModel) { var uploadedfile = viewModel.File;// Here you can get the uploaded file. //Now you can check for model state is valid or not. if(ModelState.IsValid) { //do something } else { return View(viewModel); } }

这对我有用！

是的，您可以将HttpPostedFileBase添加到ViewModel中，然后将enctype = "multipart/form-data"添加到您的From in HTML中。
