这是我的第一个ASP MVC项目 - 这是一个简单的调查，我开始只有几个问题。但是，我在“创建”页面上的提交按钮不起作用，我不知道为什么...
创建一个新的MVC项目后，我创建了一个“Survey”模型，其中包含SurveyID和2个属性（用于保存2个调查问题的答案）。然后，我基于此Survey模型创建了一个带有Views的新Scaffolded Controller。我只需要创建，所以我删除了所有的细节，编辑等等。我尝试设置我的视图，以便在Home下面是一个索引，这是你看到的初始页面，以及一个“EndOfSurvey”，这是假设的在提交调查答案后，你会看到什么。在索引上，您可以点击“下一步”按钮，进入“调查创建”页面。您回答问题，然后点击提交它的“完成”按钮，然后转到EndOfSurvey。 Create上的'Done'按钮没有做任何事情 - 我尝试在Create Post的第一行设置一个断点，它甚至没有达到那个断点。以下是我尝试的一些事情的代码。
请注意，我意识到我可能需要根据所选的单选按钮告诉它每个属性应具有的值。这是一个单独的问题。但我认为如果提交按钮正常工作，它至少应该触发创建，对吧？

Async Function Create(<Bind(Include:="SurveyID,mddbccu,mddtfuu")> ByVal survey As Survey) As Task(Of ActionResult)
If ModelState.IsValid Then
db.Surveys.Add(survey)
Await db.SaveChangesAsync()
Return RedirectToAction("EndOfSurvey")

Return View(survey)
End Function
Protected Overrides Sub Dispose(ByVal disposing As Boolean)
If (disposing) Then
db.Dispose()
End If
MyBase.Dispose(disposing)

基于我发现的其他几个问题，我试过了：
将@Using（Html.BeginForm（））更改为@Using（Html.BeginForm（“创建”，“调查”，FormMethod.Post））
在视图中注释掉“脚本”部分
同时注释掉“If ModelState.IsValid ..”并将我的断点放在db.Surveys.Add（调查）上。它仍然没有达到我的断点。
目前还不确定还有什么可以尝试的。有任何想法吗？非常感谢你！
调查模型：
Imports System.ComponentModel
Namespace ProSurvey.Models
Public Class Survey
Private surveyIDInt As Integer 'Survey ID
Private mddbccuStr As String
Private mddtfuuStr As String
Public Property SurveyID() As Integer
Get
Return surveyIDInt
End Get
Set(ByVal value As Integer)
surveyIDInt = value
End Set
End Property
Public Property mddbccu() As String
Get
Return mddbccuStr
End Get
Set(ByVal value As String)
mddbccuStr = value
End Set
End Property
Public Property mddtfuu() As String
Get
Return mddtfuuStr
End Get
Set(ByVal value As String)
mddtfuuStr = value
End Set
End Property
End Class
End Namespace

提交按钮应位于表单的@Using中：
@ModelType ProSurvey.ProSurvey.Models.Survey
@Code
ViewData("Title") = "Create"
Layout = "~/Views/Shared/_Layout.vbhtml"
End Code
