C# 未在asp.net mvc中发布Ajax表单

我有一个表单，可以上载具有指定名称和类别的文件。我已经设置好了，所以使用ajax.beginform调用在页面上发布文章。当我点击submit时，它除了重定向到页面外什么都不做

表格：

---

新的一点是，它开始无法解析action AttachFile。我做错了什么？

我认为您需要添加如下enctype属性：

    @using (Ajax.BeginForm("YourAction", "YourController",
                    new AjaxOptions() { HttpMethod = "POST", //More options here },
                    new { enctype = "multipart/form-data"}))

编辑：使用硬编码的categoryId和CollaborationId编辑代码

结果:

重定向到哪个页面？这个视图放在哪里？是否引用了jquery.unobtrusive-ajax.js？是的，视图放置的位置。是的，我有js Referenced此视图是否与“AttachFile”操作从同一控制器返回？返回的视图不在同一控制器中。可能控制器操作上方缺少[HttpPost]属性我已更新代码以包含我当前拥有的内容我已测试过您的代码，效果良好。我所做的唯一更改是硬编码CollaborationId和categoryId

[HttpPost]
    public ActionResult AttachFile(int CollaborationId, string FileDescription, int categoryId, HttpPostedFileBase FileContents)
    {
        if (FileContents != null && FileContents.ContentLength > 0)
        {
            var fileName = FileContents.FileName;
            var mimeType = FileContents.ContentType;                
            var fileLength = FileContents.ContentLength;
            byte[] fileData = new byte[fileLength];
            FileContents.InputStream.Read(fileData, 0, fileLength);

            var response = DchServiceUtility.ServiceClient.AddAttachmentToCollaboration(CollaborationId,
                CurrentUser.Id, mimeType, FileDescription, fileName, fileData, categoryId, AppSettings.ClientName);

        }

        return RedirectToAction("Details", "Collaborations", new { @id = CollaborationId });
    }

    @using (Ajax.BeginForm("YourAction", "YourController",
                    new AjaxOptions() { HttpMethod = "POST", //More options here },
                    new { enctype = "multipart/form-data"}))

    @using (Ajax.BeginForm("AttachFile", "Home", null, new AjaxOptions { HttpMethod = "Post", UpdateTargetId = "filesuccess", OnSuccess = "addFileSuccess", OnFailure = "addFileFailure" }, new { enctype = "multipart/form-data" }))
    {
    <div class="modal-body" id="addfilemodaltext">
        <div class="form-group">
            <div class="control-label">Select file to add to this collaboration:</div>
            @Html.Hidden("CollaborationId", 1)
            <input type="file" name="FileContents" id="FileContents" />
        </div>
        <div class="form-group">

            @Html.TextArea("FileDescription", null, new { @class = "form-control" })
        </div>

            <div class="control-label">Select a Category for this file:</div>
             @Html.Hidden("categoryId", 1)
        </div>
    </div>
    <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
        <input type="submit" class="btn btn-primary" id="addfilebtn" value="Upload File" />
    </div>
    }
