    Get Max Value of a List

    Hi guys, I got the following code:

    var total = Umbraco.Content(34839).Children.Where("Visible").ToList();

    My Children content have a field called value, I want to get all the values and then get max value. I know that using List

    Best Regards

    Hi Vanilson,

    You could do something like this:

    var total = Umbraco.Content(34839).Children.Where("Visible").ToList().Select(c=> c.GetPropertyValue<int>("value")).ToList().Max();

    Basically, that (may not be 100% accurate and need a bit of tweaking), should select a list of your property "value" with the contents converted to an int. It should then find the max in that list.

    I don't think you'll need the ToList(). Max() will work with the IEnumerable returned from the Select()

    Good point, I was on a little bit of auto pilot while I wrote the statement. Had List's stuck in my head.

    Hi Vanilson,

    Try changing from Umbraco.Content to Umbraco.TypedContent. Umbraco.Content starts the whole lot working on dynamic content where as Umbraco.TypedContent will start the process using IPublishedContent.
