How to check items in a Collection contains common property?

John ph

Is there any better way in c# to check items in a collection contains common property besides looping through with a flag and finding out? say for example, a text item collection contains fontweight bold for all text item

Not really. You may be able to do it with Linq, but how to do that will depend on the items you are talking about.

Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together. Manfred R. Bihy: "Looks as if OP is learning resistant."

trying to do something like this

textBold.Checked = true;
foreach (Item item in Items)
{
if (item.FontWeight == FontWeights.Normal)
{
textBold.Checked = false;
}
}

but FontWeights include more values

Add a break: textBold.Checked = true;

foreach (Item item in Items)
{
if (item.FontWeight == FontWeights.Normal)
{
textBold.Checked = false;
break;
}
}

As I said, you could do it with Linq:

        int normal = Items.Count(item => item.FontWeight == FontWeights.Normal);

Now the solution doesn't make much sense because you've removed a link in the chain. Other people might have found this useful, but you've made it hard for them. Never, ever, remove a message that's been replied to.

I agree, however IMO you're asking the wrong person. It is Chris who simply shouldn't present a "Delete" widget for messages that have replies. I have asked him many times, he eventually fixed half of it (the top level message). :)

I know. I was going to post a request and then thought, what's the point - it's been asked for before and still isn't here.

thanks a lot. implemented by storing the item properties in a list and list.contains(FontWeights.Normal). it worked.

I've asked for it on Q&A as well a few times - it really annoys me when you answer a question and it gets deleted because they (presumably) don't want the answer to help anyone else...

I remember some sites where it was expected to remove a problem once it got solved. CP however doesn't expect that; it does offer a "Delete" widget, and when used, you're bound to get "don't do that" comments. Pretty confusing if you ask me. :)

Yes, and I have no problem with it's existence. If you post a stupid question, and that makes you realise just how dumb you have been, then deleting it before anyone notices or answers is fine by me. But, when it is a complicated answer that can take half an hour to get right, and the OP deletes it as soon as he reads it, that does annoy me, I admit. If nothing else, it doesn't appear in any list I can access to copy it or refer anyone else to next time...
