Question

I have object A which contains multiple instances of object B, which in turn contains multiple instances of object C. I need to write a function which, given Object A needs search through instances of objects B and objects C and find a particular object C. How would I do this using LINQ?

        var objectC1 = new ObjectC() { id = 3 };
        var objectC2 = new ObjectC() { id = 1 };
        var objectB1 = new ObjectB() { objectCs = new List<ObjectC> { objectC1, objectC2 } };
        var objectBList = new List<ObjectB> {objectB1};
        var objectA = new ObjectA() { objectB = objectBList};

        var result = objectA.objectB.Select(b => b.objectCs.Where(c => c.id == 3));
