c# - 在 ASP.NET MVC 中将对象数组发送到服务器时出现问题

Question

我正在使用ASP.NET MVC 4. 我正在尝试将对象数组发送到控制器。我的观点包含：

<input type="hidden" id="1" name="Persons" value='[
 {"Id":1,"Name":"Abc","Description":"this is desc"},
 {"Id":2,"Name":"def","Description":"this is desc"},         
 {"Id":4,"Name":"ghi","Description":"this is desc"}]'
/>

我的控制器动作是这样的：

public ActionResult create(List<Person> Persons)
{
  //Here the Persons count is always 0, why ?
} 

当我发布我的表格时，我总是得到人数 0。有人可以帮我解决这个问题吗？

Answer 1

尝试将您的输入值更改为：

{Persons: [
    {"Id":1,"Name":"Abc","Description":"this is desc"},
    {"Id":2,"Name":"def","Description":"this is desc"},         
    {"Id":4,"Name":"ghi","Description":"this is desc"}
