Just some ranting.. any good solutions to this unlike something like this?

if (myProductSelection.Count() != 0)
{
    //loop through products in selection
    foreach (var aProduct in myProductSelection)
    {
        Console.WriteLine("Found product:" + aProduct.Code);
    }
}
else
{
   Console.WriteLine("No products found!");    
}

- Life would be so much easier if I had the source code!
- If C# had true garbage collection, most applications would delete themselves upon execution
