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"/>
    }

控制器：

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

    }

班级用户：

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

正确传输值'celo'和'pispis'。我有一个对象数组'userji'的问题 - 它在控制器上是null。有没有办法使用提交表单将对象数组传递给控制器？

Answer 1

@FrenkyB您可以将绑定更改为字符串，然后将其消化为这样的列表。

public void Test(int celo, string pispis, string userji)
{
    var myList = JsonConvert.DeserializeObject<List<User>>(userji);

    //stuff
}

@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"/>
}

我知道做你所要求的唯一方法就是作弊。我过去做的方式是作为字符串传递，然后在控制器端将数据解析为JSON。

将对象数组作为隐藏字段值传递到mvc控制器中
