Question

I have two C# (3.5) types that are different from each other. I do not control them so I can not make them inherit from a common type or implement an interface. But they are very similar in ‘shape’:

class A { string Name string Data }  class B { string Title string OtherStuff }  class C { string ID string ExtendedData }  List< A > myAList List< B > myBList 

I would like to do the following with a LINQ query:

Return all the elements in lists myAList and myBList ordered by Name or Title (whatever applies) the result must be a List< C > where ID = Name or Title and ExtendedData = Data or OtherStuff

Thoughts?

Answer 1

var myCList = (myAList.Select(a => new C     { ID = a.Name, ExtendedData = a.Data })     .Union(myBList.Select(b => new C         { ID = b.Title, ExtendedData = b.OtherStuff }))     .OrderBy(c => c.ID)     .ToList();
