c＃实体框架 - 插入数据

Question

我正在使用实体框架并尝试将数据保存到我的数据库中，但我的代码什么也没做。

public SoullutionEntities db = new SoullutionEntities();
Answers answers = new Answers();
answers.questionID = 1;
answers.answer = "yes";
db.Answers.Add(answers);
db.SaveChanges();

答案类：

namespace MMPI2_Test.Model { 
    using System; 
    using System.Collections.Generic; 

    public partial class Answers { 
        public int Id { get; set; } 
        public string answer { get; set; } 
        public int questionID { get; set; } 
        public virtual Question Question { get; set; } 
    } 
}
