c# - how to compare two list objects in fluent LINQ -

i have 2 lists have different type of objects

list<type1> list1 list<type2> list2 

the common things between type1 , type2 id property , date property.

how list of items have both id , date property equal each other?

var list3 = list1.where(x=>x.id == ?? 

thanks

you can join on multiple fields, you'll need else store values in.

assuming other properties different between type1 , type2, you'll need third class stores information want keep.

var results     = (from l1 in list1        join l2 in list2 on new { l1.id, l1.date} equals new { l2.id, l2.date }        select new somethirdclass { });
