1. What do I need to reference or use to use exemptions? I am porting some VB.NET code and I cannot use exemptions and it says (perhaps you're missing a reference or using statement)

2. Why isn't their a ListBox1.Items.Item in C#? I need to use it!

3. ListBox1.Items.Count() doesn't work the same in C## as it does in VB.NET. It denotes a property when it expects a method. how do I make it work like VB's cout()?
