如何在Html.BeginForm和sumbit FilesList中使用@ FileUpload.GetHtml [英] How to use @FileUpload.GetHtml inside Html.BeginForm and sumbit FilesList

问题描述

@ FileUpload.GetHtml有一个默认的提交按钮.但是我希望HTML开头表单中有一个提交按钮，并使用该替换来提交带有更多参数的文件列表.但是，当我这样做时，在Action方法中，传递的IEnumerable始终为null.

There is a default submit button for the @FileUpload.GetHtml. But I am expecting to have a submit button inside the Html begin form and use that substitution to submit the list of files with some more parameters. But when I do that the passing IEnumerable is always null in the Action method.

这是我的操作方法: [HttpPost] 公共ActionResult更改(IEnumerable filesList，Guid ID，字符串Btn) {....

This is my Action method: [HttpPost] public ActionResult Change(IEnumerable filesList, Guid ID, string Btn) {....

    @using (Html.BeginForm("Change", "Home",FormMethod.Post))
    {
      <textarea id="textArea" name="epost2" class="frm_txtfield_big" style="float:left; width:638px; height:200px;"></textarea>

      <input type="hidden" name="supportID" value="@Model.ID" />

      @FileUpload.GetHtml(name: "ChooseFile",initialNumberOfFiles: 1,allowMoreFilesToBeAdded: true,includeFormTag: false)

      .......}

但是，这并未将文件列表传递给该方法.

But this is not passing the list of files to the method.

我做错了或代码有什么问题.

Am doing it wrong or what is the wrong with the code.

推荐答案

我没有将enctype = "multipart/form-data"包含在Html.BeginForm内，因此该值不会被带到文件输入中.现在可以了. 这会给您一个很好的解释.

I have not included the enctype = "multipart/form-data" inside the Html.BeginForm So that the value is not taken to the file input. Now it ok. This will give you a good explanation.
