I have a model with list items.
public class Semester{
public int Id { get; set; }
public List<SemesterParent> Parents { get; set; }
}
public class SemesterParent{
public int Id { get; set; }
public int SemesterId { get; set; }
public int ParentId { get; set; }
}
I have a list<int>
of parentids
. I want to get semester
list that Parents
in parentids
list.
For example
Semester{1,{}}
Semester{2,{}}
Semester{3,{1,2}}
Semester{4,{1}}
Semester{5,{2,4}}
When I have ParentIdes {1,2}
the result is:
Semester{3,{1,2}}
Semester{4,{1}}
I use this code.
var parentIds =
await _semesterTermStudentService.Select(m => m.IsAccept && m.StudentId == student.Id);
var semester=await _semesterService.FindAsync(m=>
m.Parents.Any(y => parentIds.Contains(y.ParentId)));
You can do as below. Here is the working code
List<Semester> s = new List<Semester>();
var parentIds = new List<int> { 1, 2 };
var result = s.Where(x => x.Parents != null && x.Parents.Any() && x.Parents.All(y => parentIds.Contains(y.Id))).ToList();
