Using "as" and expecting a null return
- by DrLazer
For example. Lets say we have a stackpanel on a form. Its full of both Grids and Labels. I want to loop through all the Grids and do some operation on them but leave the Lables intact. At the moment I am doing it this way.
foreach(UIElement element in m_stacker.Children)
{
Grid block = element as Grid;
if(block != null)
{
//apply changes here
}
}
So i'm using the fact that "as" returns null if it cannot cast into the required type. Is this an ok thing to do or is there a better solution to this problem?
