Asp.net mvc ASP.net MVC 3处理“我的表格”每行中的多个复选框

我正在为猜字游戏建立一个管理员界面，这样管理员用户可以通过选择游戏中出现的单词，然后选择单词中的哪些字母将被编码来设置游戏

这是我的视图模型

public class SelectedLineWord

        [Required]

        [Required]
        public String LineWord { get; set; }


        public int[] DisplayCharPosition { get; set; }

        [Required]

        public SelectedLineWord(Guid linewordid, String word, String displaycharposition)
        {
            LineWordId = linewordid;
            LineWord = word;
            String[] pos = displaycharposition.Split(',');

            DisplayCharPosition = new int[word.Length];

            for (int i = 0; i < word.Length; i++)
            {
                DisplayCharPosition[i] = 0;
            }

            for (int i = 0; i < pos.Length; i++)
            {
                DisplayCharPosition[Int32.Parse(pos[i])] = 1;
            }
        }

        public SelectedLineWord(Guid linewordid, String word, bool issel)
        {
            LineWordId = linewordid;
            LineWord = word;
            isSelected = issel;
        }

    } 

    public class GameTableModel
    {

        [Required]
        public Guid GameTableId { get; set; }

        [Required]
        public Guid GameMatrixId { get; set; }

        [Display(Name = "Table Subject")]
        public Dictionary<int, string> Subjects;

                var data = new GameServerDataModelDataContext();

                //Fetch the subjects reference data
                var subjects = from c in data.Subjects orderby c.Subject1 select new { c.SubjectId, c.Subject1};

                Subjects = new Dictionary<int, string>();

                foreach (var subject in subjects)
                {
                    Subjects.Add(subject.SubjectId, subject.Subject1);
                }

                //Fetch the complexities questions
                Table<Complexity> dComplexities = data.GetTable<Complexity>();

                Complexities = new Dictionary<int, int> { { 0, 0 } };
                foreach (var complexity in dComplexities)
                {
                    if (complexity.Complexity1 != null)
                        Complexities.Add(complexity.ComplexityId, (int)complexity.Complexity1);
                }

            }
            catch (Exception ex)
            {
                //[TODO: Complete the exception handeling code.]
            }
        }
    }

public类SelectedLineWord
{
[必需]
公共Guid LineWordId{get；set；}
[必需]
公共字符串行字{get；set；}
public int[]DisplayCharPosition{get；set；}
[必需]
公共布尔值被选为{get；set；}
公共选择的LineWord（）
{
}
public SelectedLineWord（Guid linewordid、String word、String displaycharposition）
{
LineWordId=LineWordId；
LineWord=单词；
字符串[]pos=displaycharposition.Split（'，'）；
DisplayCharPosition=新整数[字长]；
for（int i=0；i

我的问题是，当我点击save按钮时，传递给控制器的模型已正确填充了所有内容，但为DisplayCharPosition选择的复选框返回null。我所期望的是一个int[]，填充了所选显示字符的索引

有人能帮我理解我做错了什么吗

我已经设法解决了这个问题（但我仍然愿意接受一些关于更好的建议）

public class SelectedLineWord 
    {
        [Required]
        public Guid LineWordId { get; set; }

        [Required]
        public String LineWord { get; set; }


        public bool[] DisplayCharPosition { get; set; }

        [Required]
        public bool isSelected { get; set; }

        public SelectedLineWord()
        {

        }

        public SelectedLineWord(Guid linewordid, String word, String displaycharposition)
        {
            LineWordId = linewordid;
            LineWord = word;
            String[] pos = displaycharposition.Split(',');

            DisplayCharPosition = new bool[word.Length];

            //set all to false
            for (int i = 0; i < word.Length; i++)
            {
                DisplayCharPosition[i] = false;
            }

            //now only set the ones that were already in the db.
            for (int i = 0; i < pos.Length; i++)
            {
                DisplayCharPosition[Int32.Parse(pos[i])] = true;
            }
        }
