Mainly that it does work with Struts.

Here is another example. You are loading a TreeView, every tree node has it’s tag set to a number. You catch the AfterSelect event and do this:

private void BuildingStructureTreeView_AfterSelect(object sender, TreeViewEventArgs e)
{
var value = e.Node.Tag.CastOrDefault());
}

That said, the “as ” will work for most cases.

Except for structs what is different with just using as?

1: private Label GetLabel(string name)

2: {

3: return this.Controls[name] as Label;

4: }
