ASP.NET核心MVC无法绑定检查框列表

public class MyViewModel
{
    public List<SelectListItem> CheckBoxList { get; set; }
    // 其他相关数据
}

public IActionResult MyAction()
{
    var viewModel = new MyViewModel();
    viewModel.CheckBoxList = new List<SelectListItem>
    {
        new SelectListItem { Value = "1", Text = "选项1" },
        new SelectListItem { Value = "2", Text = "选项2" },
        new SelectListItem { Value = "3", Text = "选项3" }
    };

    return View(viewModel);
}

@model MyViewModel

<form asp-action="Submit" method="post">
    @for (int i = 0; i < Model.CheckBoxList.Count; i++)
    {
        <div>
            <input type="checkbox" name="SelectedValues" value="@Model.CheckBoxList[i].Value" />
            <label>@Model.CheckBoxList[i].Text</label>
        </div>
    }
    <button type="submit">提交</button>
</form>

[HttpPost]
public IActionResult Submit(string[] selectedValues)
{
    // 处理选中的复选框的值
    // ...

    return RedirectToAction("Success");
}
