.NET Core Blazor：如果选中Checkbox值，如何获取它？

@page "/registration"

    @foreach (var club in ClubList())
    {
        <input type="checkbox" @onchange="eventArgs => { CheckboxClicked(club, eventArgs.Value); }" />@club<br />
    }

@functions {

    public List<string> ClubMember { get; set; } = new List<string>();
    void CheckboxClicked(string clubID, object checkedValue)
    {
        if ((bool)checkedValue)
        {
            if (!ClubMember.Contains(clubID))
            {
                ClubMember.Add(clubID);
            }
        }
        else
        {
            if (ClubMember.Contains(clubID))
            {
                ClubMember.Remove(clubID);
            }
        }
    }

    public List<String> ClubList()
    {
        // fetch from API or...
        List<String> c = new List<String>();
        c.Add("Clube01");
        c.Add("Clube02");
        return c;
    }

}
