find function of List

Problem is the following line of code. There is accuring an error. argument 1 cannot convert form annonymous method 1o predicate obj.Find(delegate(person p) { return p.age = 12; });

I guessed that, it's just that, like always, you're guessing how the code should look instead of doing research, and making posts that don't give half way enough information to help people to help you. public class person { public string name; public int age; public person(string nam , int ag) { this.age = ag; this.name = nam; } } public class Program { public static void Main(string[] args) { List<person> obj = new List<person>(); obj.Add(new person("abc",22)); obj.Add(new person("ggbc1",12)); obj.Add(new person("ccc2",10)); obj.Add(new person("cabc3",12)); obj.Add(new person("bbbc4", 6)); Predicate<person> exists = delegate(person p1) { return p1.age == 12; }; person p = obj.Find(exists); } } } Note that find will only return one object, you can use FindAll to get a list back.

Sonia - I've already told you what the answer is. Read the full text above.

Sonia - what error is the compiler returning? I'll give you a hint - you should use == not = in the check, but the compiler would have told you this. You have to learn how to interpret compiler errors rather than reaching for CodeProject as soon as you get an error you've not seen before. This and the error you posted below could both have been found with a little bit of effort and research on your part.

Mate, that was the least of her problems.

Sonia - I thought that I would see whether Google would have been able to answer your question. You know what? The first entry in the list matched your problem exactly. Why not try reaching for google rather than using us to help you compile your code? It'll help you become a better developer in the long run.

can i use two filters in the find statement , according to there should not be two return statements in a single block. But i have to set two where conditions to refine the record.

You think this hasn't been said to her before ? She's lucky I got interested enough in the fact I didn't know the solution off the top of my head. And yes, I googled and the first hit told me exactly what to do, so I mocked up a sample for my own benefit as much as hers. I love the idea of anonymous predicates, but I don't find myself searching lists often enough to really use them.

Wow - you didn't listen to a thing he said, did you ? You have a function that returns bool. It's up to you, through the writing of actual code, to decide when that is true, or false. It can depend on as many different conditions as you like.

This time , i think u did not care to look the question carefully. the new question has nothing to do with the prior one.

True - but it represents you ignoring what has been said to your countless times, not even thanking either of us for doing your job for you, and pressing on with the next thing you can't work out. I answered the question, didn't I ?

I know that we've both told her this many times. If I search through her history, I can find countless examples where she's been told to learn the basics. I can only hope that one day she might have the sense to think "Wait a second. These guys do know what they are talking about."

Why not try it? Rather than asking me to do your thinking for you, why not try it yourself. Honestly - it's as though you are being deliberately stupid.
