Check Object type in List of Objects

Question

Got a WPF Form with a StackPanel containing Expanders with StackPanels in it.

Answer 1

I would do something like this: use the Enumerable.OfType<>()

More info: https://msdn.microsoft.com/en-us/library/vstudio/bb360913(v=vs.100).aspx

foreach(var stackpanel in tmpList.OfType())
{
    // search for the label. (the same trick)
    var myLabel = stackpanel.Children.OfType().FirstOrDefault();

    // if the label can't be found, continue to the next one.
    if(myLabel == null)
        continue;

    myLabel.Content = "whatever";
}
