arrays - 将对象数组作为隐藏字段值传递给 mvc Controller

Question

我正在使用 VS2015，MVC5。
我的提交表格:

        @using (Html.BeginForm("Test", "Home", FormMethod.Post))
    {
        <input name="celo" type="hidden" value="994" />
        <input name="pispis" type="hidden" value="Došel je prošel pisani Vuzem!" />
        <input name="userji" type="hidden" 
            value="[{'ID':1,'Name':'John','TotalPayed':0,'TotalDebt':0},
                {'ID':2,'Name':'George','TotalPayed':0,'TotalDebt':0},
                {'ID':3,'Name':'Simon','TotalPayed':0,'TotalDebt':0},
                {'ID':4,'Name':'Antonio','TotalPayed':0,'TotalDebt':0}]" />
        <input type="submit" value="Submit test"/>
    }

Controller :

    public void Test(int celo, string pispis, List<User> userji)
    {

    }

类(class)用户:

    public class User
{
    public int ID { get; set; }
    public string Name { get; set; }
    public int TotalPayed { get; set; }
    public int TotalDebt { get; set; }         
}

值 'celo' 和 'pispis' 被正确传输。我对对象数组“userji”有疑问 - 它在 Controller 上为空。有没有办法使用提交表单将对象数组传递给 Controller ​​？

@using (Html.BeginForm("Test", "Home", FormMethod.Post))
{
    var users = new List<User> 
    {
        new User { Name = "John", TotalPayed = 0, TotalDebt = 0 },
        new User { Name = "George", TotalPayed = 0, TotalDebt = 0 },
        new User { Name = "Simon", TotalPayed = 0, TotalDebt = 0 },
        new User { Name = "Antonio", TotalPayed = 0, TotalDebt = 0 }
    };

    <input name="celo" type="hidden" value="994" />
    <input name="pispis" type="hidden" value="Došel je prošel pisani Vuzem!" />

    @for(int i = 0; i < users.Count; i++)
    {
        var user = users[i];

        <input name="userji[@i].Name" type="hidden" value="@user.Name" />
        <input name="userji[@i].TotalPayed" type="hidden" value="@user.TotalPlayed" />
        <input name="userji[@i].TotalDebt" type="hidden" value="@user.TotalDebt" />
    }

    <input type="submit" value="Submit test"/>
}
