C# LINQ to Entities does not recognize the method 'Boolean'

Question

I have the following linq expression in lambda syntax:

var myValue = 6;
var from = 2;
var to = 8;

var res = MyList.Where(m => m.person.Id == person.Id
           


        

Answer 1

In Addition to this, if you want to pass the values to IsBetween method from MyList.

Take a wrapper class (here Person) contains the same properties to be passed to the method. and do something like this:

var res = MyList.Where(m => m.person.Id == person.Id)
            .Select(x => new Person { p1 = x.p1, p2 = x.p2 })
            .AsEnumerable()
            .where(x => (IsBetween(x.p1, x.p2)))
            .ToList());
