    foreach with Where statement to check IsEven()

    Razor

    Does somebody know the solution for a foreach loop for showing only the even (isEven()) items?

    Current code doesn't work:

    dynamic appItems = Model.Children;
    @foreach (dynamic c in appItems.Where("IsEven()"))
    {
     ...
}

    Hi,

    I'm not sure there's a way to do this using IsEven - unless you loop through all the items and run a check inside the loop (ie is c.IsEven() { ... } ).

    There is a way you can do this in pure C# though (see this thread) if you use ChildrenAsList, something like this should work:

        var appItems = ((DynamicNode)Model).ChildrenAsList;
        foreach (var c in appItems.Where((x, c) => c % 2 == 1))
        {
        }

    HTH,
    Tom
