- [Narrator] After that brief diversion,…we now return you to your regularly scheduled program.…We've seen the ForLoop.…Let's try a ForEachLoop.…So, ForEachLoop in actually used heavily…in the context of working with arrays and lists,…so I'll do almost the same kind of loop.…This will be a ForEachLoop though…and as I said, we'd like to use these with lists,…so let's create a new list and I'll call it numbers…equals new list and it will be of type integer…and just to keep things fresh,…I'm going to show you a slightly different way…to initialize your list before we would just hit…our semicolon here and then, we would say numbers.ad,…but let me show you something a little bit different.…
I can actually use what's called the Collection Initializer…here and I can do this in one step, so let's add…in our numbers one, three, five, seven and nine.…Since our objective here is to add up all the numbers…in the list, I'll create a variable…called sum and set it equal to zero.…Now for the ForEachLoop.…I'll just say foreach(var number in numbers);…
