c# - Console.WriteLine and generic List

I frequently find myself writing code like this:

List<int> list = new List<int> { 1, 3, 5 };
foreach (int i in list) {
    Console.Write("{0}", i.ToString()); }
Console.WriteLine();

Better would be something like this:

List<int> list = new List<int> { 1, 3, 5 };
Console.WriteLine("{0}", list);

I suspect there's some clever way of doing this, but I don't see it. Does anybody have a better solution than the first block?

Do this:

list.ForEach(i => Console.Write("{0}", i));

EDIT: To others that have responded - he wants them all on the same line, with tabs between them. :)
