Question

I am trying to replace following statement with the lambda expression:

 List<ABC> l = new List<ABC>();
  l.Find(delegate(ABC a) { return a.A == 4; });

I tried

 l.Find((ABC a)=>a.A==4;);

but that is obviously incorrect.
Thanks

Answer 1

Firstly, note that it is still a delegate – simply: rather, it uses the lambda syntax rather than the anonymous method syntax (it essentially means exactly the same thing, though).

As for how to fix it: just take away the ;:

l.Find((ABC a) => a.A == 4);

or more simply:

l.Find(a => a.A == 4);

(brackets are only necessary if you have multiple parameters; explicit types are useful for disambiguation)
