上传图片MVC始终为null [英] Upload Image MVC always null

问题描述

大家好，我正在尝试上传一个简单的图像，但是HttpPostedFileBase始终为null.这是我的代码，我不知道自己在做什么错.

Hi everyone i am trying to upload a simple image but the HttpPostedFileBase is always remaining null. This is my code i dont know what i am doing wrong.

这是我在设计视图中的代码:

This is my code in the design view:

<fieldset>
    <legend>PictureModel</legend>

    <div class="editor-label">
        <%: Html.LabelFor(model => model.PrivacyTypeID) %>
    </div>
    <div class="editor-field">
        <%: Html.DropDownList("PrivacyTypeID", null, new { name = "PrivacyTypeID", title = "Please select privacy type.", id = "PrivacyTypeID" }) %>
        <%: Html.ValidationMessageFor(model => model.PrivacyTypeID) %>
    </div>
    <div class="editor-label">
        <%: Html.LabelFor(model => model.File1) %>
    </div>
    <div class="editor-field">
        **<input type="file" name="File1" />**
        <%: Html.ValidationMessageFor(model => model.File1) %>
    </div>        
    <div class="editor-label">
        <%: Html.LabelFor(model => model.Description) %>
    </div>

这是我的控制器中的代码:

And here is the code in my controller:

public ActionResult AddPicture(向导ID，PictureModel模型，HttpPostedFileBase File1) { 尝试 {

public ActionResult AddPicture(Guid id, PictureModel model, HttpPostedFileBase File1) { try {

            if (ModelState.IsValid)
            {
                try
                {
                    Guid albumid = id;

                    if (File1 != null)
                    {
                        var physicalPath = Path.Combine(Server.MapPath("~/Gallery"), System.IO.Path.GetFileName(File1.FileName));
                        File1.SaveAs(physicalPath);
                        PicturesBL pictures = new PicturesBL();

任何人都可以告诉我这是什么问题吗?

Can anyone please tell me what is the problem??

推荐答案

这也使我发疯.几个小时后我意识到，

This was driving me crazy too. After hours I realized, that

@Scripts.Render( "~/bundles/jquerymobile")

_Layout.cshtml中的

导致了此问题.注释掉后，上传成功.

in _Layout.cshtml was causing the problem. When commented out, the upload worked.

请参见 http ://forum.jquery.com/topic/jquery-mobile-seems-to-clobber-ability-to-upload-files-via-forms 了解详情.

在表单中添加

data_ajax="false"

属性可以解决该问题.
