Initialize a byte array to a certain value, other than the default null? [duplicate]
...he square brackets [] to declare an array. Also, your constants need to be convertible to byte, which numbers (ints) such as 4, 3, and 2 are not. So it has to be: new byte[] { (byte) 4, (byte) 3, (byte) 2}, or the hex syntax.

Shorter syntax for casting from a List to a List?
...like more control over the casting / conversion process, you could use the ConvertAll method of the List<T> class, which can use a supplied expression to convert the items. It has the added benifit that it returns a List, instead of IEnumerable, so no .ToList() is necessary.
