首先，我不会尝试将 IQueryable 用于 Keywords 属性，***使用 IList.其次，将关键字和 CheckboxList 组合成一个属性可能会更好，让您的关键字类是这样的:

Firstly I would not attempt to use IQueryable for your Keywords property, better would be to use IList. Secondly it would probably be better to combine Keywords and CheckboxList into a single property, having your keyword class something like this:

public class Keyword
{
    public int KeywordId {get;set;}
    public bool Checked {get;set;}
}

所以 ThesisWithKeywordsModel 看起来像这样:

So ThesisWithKeywordsModel would look like this:

public class ThesisWithKeywordsModel
{
    public Thesis thesis { get; set; }
    public IList<Keyword> keywords { get; set; }
}

然后在您的控制器中，您应该能够:

Then in your controller, you should be able to do:

thesis.keywords = db.KeywordRepository.GetAllKeywords()
                     .Select(kw => new Keyword
                     {
                        KeyeordId = kw.KeywordId,
                        Checked = false
                     }).ToList();

接下来，当将值列表传入/传出视图时，您需要将 cshtml 中的 foreach 循环更改为 for 循环.

Next you need to change your foreach loop in the cshtml into a for loop when passing a list of values to/from the view.

for(var i = 0; i < Model.keywords.Count; i++)
{
    <input type="checkbox" id="@Model.keywords[i].KeywordId" name="checkboxList" checked='@Model.keywords[i].Checked ? "checked" : ""'>
    <label for="@Model.keywords[i].KeywordId">@Model.keywords[i].Value</label><br/>
}
