C# Cast list using Linq using Where function -

i'm trying optimize part of function gets objects within unity contains component.

current code looks this

collider[] collisions = physics.overlapsphere(point, range); foreach (collider item in collisions) {       if (item.getcomponent<rigidbody2d>())       {            rigidbodies.add(item.getcomponent<rigidbody2d>());       } } 

first list of objects colliders, run thought foreach loop ones contains rigidbody2d component

i'm trying turn single line of code using linq. i'm trying along line

collider[] collisions = physics.overlapsphere(point, range); rigidbodies = (list<rigidbody2d>)collisions.tolist().oftype<rigidbody2d>().where(x => x.getcomponent<rigidbody2d>() == true); 

unfortunately throws invalidcastexception

you need add call tolist() on method chain.

you'll able rid of cast altogether:

rigidbodies =      collisions         .oftype<rigidbody2d>()         .where(x => x.getcomponent<rigidbody2d>())         .tolist();
