How to use TrueForAll

Question

I have a list of bools and I want to check if every one is set to true. I can run a loop and check it that way but I want to try to do it with `TrueForAll` method of a list. I need a predicate for that but I couldn't find a clear example for such a simple task as this.

Accepted Answer

Use `All`:

```
bool alltrue = listOfBools.All(b => b);
```

It will return `false` one the first `false`.

However, since you are actually using a `List<bool>` you can also use `List.TrueForAll` in the similar way:

```
bool alltrue = listOfBools.TrueForAll(b => b);
```

But since that is limited to a list i would prefer `Enumerable.All`.
