HTML表单中的空值来自MVC视图

我想保存用户的步骤，并在我的MVC索引视图的每一行是一个表单。

我正在使用HTML。在foreach中开始form，以构建单个表单。页面呈现没有错误，表单提交没有问题，但我不能绑定到控制器中的模型-因此所有提交的数据都丢失了。

我已经验证了表单值是在提交表单时开始的:item. completed =true&item. completed =false&item. comment =HELLO+WORLD+&item. finalizestepid =1&item。StepId=1，但是控制器不接受它们，并且FinalizeStepViewModel对象使用空值创建。

那么我如何让表单正确地传递回数据呢?

这可能是我在Stackoverflow上的第二个问题，所以让我知道我可能需要添加的其他信息。

谢谢。

===模型=====

public class FinalizeStepViewModel
    {
    public int FinalizeStepId { get; set; }
    // foreign key from Step table
    public int StepId { get; set; }
    // name of taks from Step table 
    public string StepDesc { get; set; }
    [DisplayName("Review Data")]
    public string ReviewFormulaValue { get; set; }
    [Required]
    public bool Completed { get; set; }
    [DisplayName("Fiscal Year")]
    public int FiscalYear { get; set; }
    // Period for the adjustment
    [Required]
    public int Period { get; set; }
    [Required]
    public string UserID { get; set; }
    [Required]
    [DisplayName("Created By")]
    public string CreatedBy { get; set; }
    [Required]
    [DisplayName("Created At")]
    public DateTime CreatedAt { get; set; }
    public string Comment { get; set; }

====查看==========@ model IEnumerable

@ {ViewBag。Title = "Index";

// is everything completed, if yes => enabled
string alldone = "enabled";

}
