在剃刀表格视图，包括文件上传 [英] Including File Upload in Razor Form View

问题描述

MVC 3，VB.NET。我在我的应用程序从用户得到基本信息的表格，然后允许他们上传简历。我现在实现这一权利通过重定向到一个不同的形式，是唯一的目的就是选择要上传的文件，然后提交它..在我看来，马虎。我已经试图从相同的形式做，但该文件是丢失的提交。虽然我不能肯定它，我相信那是因为我不使用形式正确的语法来处理文件......下面是查看到目前为止，然后控制器功能后..

  @ModelType xxxxxxxx.courseproposal
@ code
ViewData的（标题）=课程方案
结束code

 ＆LT; / DIV＆GT;＆LT; /字段集＆GT;
使用完
 

和POST功能是这样的：

 ＆LT; AcceptVerbs（HttpVerbs.Post）GT;
    功能CourseProposal（BYVAL courseprop作为courseproposal）作为的ActionResult
        courseprop.conf_Number = _AnnualNumber
        db.courseproposals.AddObject（courseprop）
        db.SaveChanges（）
        _id = courseprop.idCourseProposal
        昏暗_filename作为字符串=的String.Empty
        对于每一个文件作为字符串在Request.Files
            DIM HPF作为HttpPostedFileBase = TryCast（Request.Files（文件），HttpPostedFileBase）
            如果hpf.ContentLength = 0则
                继续
            万一
            昏暗savedfileName作为字符串= Path.Combine（AppDomain.CurrentDomain.BaseDirectory）+\\ CoursePro presumes \\+ Path.GetFileName（hpf.FileName）
            hpf.SaveAs（savedfileName）
            _filename = hpf.FileName
        下一个
 

解决方案

您需要的形式 ENCTYPE =的multipart / form-data的。

尝试

  Html.BeginForm（NULL，NULL，FormMethod.Post，新{ENCTYPE =的multipart / form-data的}）
 

修改：那当然是C＃。在VB中应该读

  Html.BeginForm（没什么，没什么，FormMethod.Post，新增功能{.enctype =的multipart / form-data的}）
 

MVC 3, VB.NET. I have a form in my app that gets basic information from the user and then allows them to upload a resume. I am accomplishing this right now by using a redirect to a different form that's only purpose is to select the file for uploading and then submit it.. Sloppy in my opinion.. I have tried to do it from the same form but the file is being lost on submit.. While I am not certain of it I believe it is because I am not using the correct syntax in the form to handle the file... Below is the View so far and then the controller post function..

@ModelType xxxxxxxx.courseproposal
@Code
ViewData("Title") = "Course Proposal"
End Code
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript">         </script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@Using Html.BeginForm()
@Html.ValidationSummary(True)
@<fieldset>
 <table>
    <tr>
        <th>Presenter 1</th>
    </tr>

    <tr>
        <td>First Name</td>
        <td>Last Name</td>
        <td>Title</td>
        <td>Phone Number</td>
        <td>Email Address</td>

    </tr>
    <tr>
        <th>@Html.EditorFor(Function(model) model.Name_First1) @Html.ValidationMessageFor(Function(model) model.Name_First1)</th>
        <th>@Html.EditorFor(Function(model) model.Name_Last1) @Html.ValidationMessageFor(Function(model) model.Name_Last1)</th>
        <th>@Html.EditorFor(Function(model) model.Title_1) @Html.ValidationMessageFor(Function(model) model.Title_1)</th>
        <th>@Html.EditorFor(Function(model) model.phone_number1) @Html.ValidationMessageFor(Function(model) model.phone_number1)</th>
        <th>@Html.EditorFor(Function(model) model.email_address1) @Html.ValidationMessageFor(Function(model) model.email_address1)</th>
         <th>@Html.Label("file","Filename:")<input type="file" name="file" id="file" />  </th>
    </tr>
</table> 

<div id="sidebar3">

 <p>
 <input type="submit" value="Submit Course Proposal" />
 </p>

 <p>
 @Html.ActionLink("Back to List", "Index")
 </p>
 </div>

</fieldset>
End Using

And the post Function is like this:

   <AcceptVerbs(HttpVerbs.Post)>
    Function CourseProposal(ByVal courseprop As courseproposal) As ActionResult
        courseprop.conf_Number = _AnnualNumber
        db.courseproposals.AddObject(courseprop)
        db.SaveChanges()
        _id = courseprop.idCourseProposal
        Dim _filename As String = String.Empty
        For Each File As String In Request.Files
            Dim hpf As HttpPostedFileBase = TryCast(Request.Files(File), HttpPostedFileBase)
            If hpf.ContentLength = 0 Then
                Continue For
            End If
            Dim savedfileName As String = Path.Combine(AppDomain.CurrentDomain.BaseDirectory) + "\CoursePropResumes\" + Path.GetFileName(hpf.FileName)
            hpf.SaveAs(savedfileName)
            _filename = hpf.FileName
        Next

解决方案

Your form needs enctype="multipart/form-data".

Try

Html.BeginForm(null, null, FormMethod.Post, new { enctype="multipart/form-data"})

EDIT: That of course is for C#. In VB it should read

Html.BeginForm(Nothing, Nothing, FormMethod.Post, New With { .enctype="multipart/form-data"})
