推荐答案

您应该换另一个对象的两个对象的视图，通常被称为一个视图模型

You should wrap the two objects in another object for the View, commonly referred to as a "ViewModel".

public class QuestionAnswerViewModel
{
   public Question Question { get; set; }
   public ICollection<Answer> Answers { get; set; }
}

绑定到您的视图。

Bind to that in your View.

然后使用类似的 AutoMapper 将其映射回你的两个实体。

Then use something like AutoMapper to map it back to your two entities.
