C# LINQ比较两个列表，每个列表在一个对象内，至少一个相等

我有一个目标学生

public class Student
{
    public int id;
    public string name;
    public ICollection<WeekDays> weekDays;
}

上课时间是这样的：

public class WeekDays
{
    public Days day;
}

public enum Days 
{
    Monday,
    Tuesday,
    Wednesday,
    Thursday,
    Friday,
    Saturday
    Sunday
}

var student1; //this is a student that have the specific values (id, names and all the weekDays, all initialized with values)

var student2 = database.Students
     .Include(x => x.weekDays)
     .Where(x =>
            x.weekDays.Any(day1 => student1.weekDays.Any(day2 => day2.WorkDay == day1.WorkDay))
     )
     .FirstOrDefaultAsync();

我想让学生与某个特定的学生至少有一个共同的一天

我是这样做的：

public class WeekDays
{
    public Days day;
}

public enum Days 
{
    Monday,
    Tuesday,
    Wednesday,
    Thursday,
    Friday,
    Saturday
    Sunday
}

var student1; //this is a student that have the specific values (id, names and all the weekDays, all initialized with values)

var student2 = database.Students
     .Include(x => x.weekDays)
     .Where(x =>
            x.weekDays.Any(day1 => student1.weekDays.Any(day2 => day2.WorkDay == day1.WorkDay))
     )
     .FirstOrDefaultAsync();

但它不起作用，这是错误：

“（我的LINQ表情在这里）”无法翻译。以可以翻译的形式重写查询，或者通过插入对AsEnumerable（）、AsAsAsAsyncEnumerable（）、ToList（）或ToListSync（）的调用显式切换到客户端计算

请尝试预先选择日期并使用

包含的内容

：

var student1Days = student1.weekDays.Select(d => d.day).ToList();
var student2 = database.Students
     .Include(x => x.weekDays)
     .Where(x => x.weekDays.Any(day1 => student1Days.Contains(day1.WorkDay)))
     .FirstOrDefaultAsync();
