In the following example we have two different exceptions we want to communicate.
//constructor
public Main(string arg){
if(arg==null)
throw new ArgumentNullException("arg");
Thing foo=GetFoo(arg);
if(foo==null)
throw new NullReferenceException("foo is null");
}
Is this the proper approach for both exception types?
