c# - ASP.NET MVC 4 : How to update model from view on submit form

Question

我创建了一些表单，我需要在提交表单上分配字段 CreationDate:

@model Namespaces.Chapter

@using (Html.BeginForm ()) {
    <p>Title: @Html.TextBoxFor(c => c.Title)</p>
    ...
    @{ Model.CreationDate = DateTime.Now;} <- somehow like that, but this code does not works
    <input type="submit" value="Submit" />
}

怎么做？

Answer 1

在将其传递给数据访问之前，您必须在 Controller 操作中执行此操作，例如:

public ActionResult SomeAction(SomeClass obj)
{
   obj.CreationDate = DateTime.Now;

   // your business logic goes here
