c# - 使用 ASP MVC 将字符串从 <form> 传递到 Controller

Question

我正在做这个小教程:http://www.asp.net/mvc/videos/mvc-2/how-do-i/creating-a-tasklist-application-with-aspnet-mvc

但不知何故，他正在将一个字符串传回 Controller 。但我无法让我的传回一个字符串。我错过了什么？

创建.aspx

<form method="post" action="/Home/CreateNew">
    <label for="task">Task:</label>
    <input type="text" name="task" />
    <input type="submit" value="Add Task" /> 
</form>

HomeController.cs

public ActionResult CreateNew(object obj ) // <-- expecting a string but getting an object.
{
  string whattype = obj.GetType().ToString(); //just an obj, expecting a string
  //add to DB next
}

MVC 是基于约定的 - 表单元素名称是 task 所以它应该是参数名称:

public ActionResult CreateNew(string task ) //<-- expecting a string but getting an object.
{
  string whattype = obj.GetType().ToString(); //just an obj, expecting a string
  //add to DB next
}
