尝试添加2学生您的评论类，例如：

Try to add 2 Students in your Review class, for example:

[Table("tb_review")]
public class Review
{    
    [Key]
    public int id { get; set; }
    public string message { get; set; }
    public Student student{ get; set; } // review of which student
    public Student reviewer{ get; set; } // whom send the review
} 

和你的学生类应该是这样的：

And your Student class should be like this:

[Table("tb_student")]
public class Student
{    
    [Key]
    public int id { get; set; }
    public string name { get; set; }
    [InverseProperty("student")]
    public List<Review> reviewAbout{ get; set; }
    [InverseProperty("reviewer")]
    public List<Review> reviewBy{ get; set; }
}
