Linq Support for FindAll

[JoshuaRHolden]

Given the following Example:

[Fact]
public void Login()
{
AuthContext.SetAuthorized("jholden", AuthorizationState.Authorized);
var CounterPage = testContext.RenderComponent<CascadingAuthenticationState>(x => x.AddChildContent<UserPage>());
CounterPage.FindAll("p")[1].MarkupMatches("<p>You are authenticated</p>");
}

Notice I know that the p element i'm looking for is the second one in the dom, is there a way of doing something like this:

CounterPage.FindAll("p").First(x=> x.ToHtml() == "<p>You are authenticated</p>");

I'm assuming that given that the only useful looking property to even think about querying the collection on IRefreshableElementCollection is count, the closest i can get to this is by looping and applying an index until .ToHtml returns the content i'm looking for, therefore I could create a extension method to acheive this locally for me, but I don't understand why it's not included as standard?

If i was to do a PR to add querying support to the element collection/ expose a list would it be accepted, is there a reason this is not available currently?

Hi @JoshuaRHolden

That would just work. Do you have the System.Linq namespace imported?

[egil]

IRefreshableElementCollection<T> inherits from IReadOnlyList<T>, so LINQ is definitely supported.

Yeah, right you are.. today I learnt I rely too much on VS errors suggesting I add the using’s it didn’t twig! Cheers!
