address all list-items

I'm trying to address all items of a list without a forEach-loop.

For example:

 ColorTextBlocks = new List<TextBlock>()
        {
            tb1,
            tb2,
            tb3,
            tb4,
            tb5,
            tb6
       }

Is it possible to change the foreground of all items in one line?

Sure, you have the List<T>.ForEach() method. 

ColorTextBlocks.ForEach(tb => tb.Color = Color.Green);

But it is debatable whether this is any 'better' than a plain foreach() loop. It certainly won't be faster.

Sure:

ColorTextBlocks.All(c => { c.ForeGround = Color.Blue; return true; });

You can also do:

ColorTextBlocks.ForEach(c => c.ForeGround = Color.Blue);

But why "in one line"? A foreach loop is traditionally more readable that Linq queries...
