在For循环内将模型对象动态分配给TextBoxFor

public class MyModel
{
    public List<string> Items { get; set; }
}

@model MyModel

@using (Html.BeginForm())
{
    for (int i = 0; i < Model.Items.Count; i++)
    {
        @Html.TextBoxFor(m => m.Items[i], new { id = "item_" + i })
    }
    <input type="submit" value="Submit" />
}

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var model = new MyModel
        {
            Items = new List<string> { "Item1", "Item2", "Item3" }
        };
        return View(model);
    }

    [HttpPost]
    public ActionResult Index(MyModel model)
    {
        // 处理提交的数据
        foreach (var item in model.Items)
        {
            // 处理每个项目
        }
        return View(model);
    }
}
