很难确定html.checkboxfor()作为LINQ表达式需要什么

标题差不多说明了一切。我有一个复杂的EF4实体对象,它有一个小对象列表,我想在我的视图中绑定到复选框。我只是不知道如何满足html.checkboxfor()的第一个参数。IntelliSense总是给我一个错误。

以下是我的视图模型:

public class PlatformListing
{
    public Platform Platform { get; set; }
    public bool IsSelected { get; set; }
}

public class AdminGameReviewViewModel
{
    public Game GameData { get; set; }
    public List<Genre> AllGenres { get; set; }
    public List<PlatformListing> AllPlatforms { get; set; }
}

以及我的(很可能很糟糕)控制器代码,它填充了admingamereviewModel并将其发送到视图:

    public ActionResult EditReview(int id)
    {
        var game = _siteDB.Games.Include("Genre").Include("Platforms").Include("Content").Single(g => g.GameID == id);
        var genres = _siteDB.Genres.OrderBy(g => g.Name).ToList();
        var platforms = _siteDB.Platforms.OrderBy(p => p.Name).ToList();
        List<PlatformListing> platformListings = new List<PlatformListing>();

        foreach (Platform platform in platforms)
        {
            platformListings.Add(new PlatformListing { Platform = platform, IsSelected = game.Platforms.Any(p => p.PlatformID == platform.PlatformID) ? true : false });
        }

        var model = new AdminGameReviewViewModel { GameData = game, AllGenres = genres, AllPlatforms = platforms }; 

        return View(model);
    }

我只是不知道我错过了什么,这让我发疯。我找到的文件也没有真正的阐明这一点。

编辑:相关视图代码(用于创建和编辑的部分视图)-
