c# - Create New List From Existing Lists Comparison -


i have 2 lists:

list<course> studentcourses = course.getcourses(student.pidm, gettermcode());   list<offeredcourse> offeredcourses = offeredcourse.getofferedcourses();

studentcourses have properties subjectcode , coursenumber.
offeredcourses have properties subjectcode , coursenumber.

i want create third list of type list<course> contains items studentcourses match both subjectcode , coursenumber of item in offeredcourses.

any appreciated.

linq uses non-intuitive syntax that: use contains collection might contain values you're after.

var result = studentcourses.where(c => offeredcourses.contains(o => o.subjectcode == c.subjectcode && o.coursenumber == c.coursenumber));
