Stop doing that - it's a pretty poor way to do things. If you are following a book, or other training course, then fine, but if you are just trying to pick it up "randomly" as you go, then stop right now! Your will miss too much stuff, which can save you a lot of time and heartache later!

static void Main(string[] args)
{
    int number = Convert.ToInt32(args[0]);
    int power = Convert.ToInt32(args[1]);
    Console.WriteLine(Math.Pow(number, power));

When I run it in the debugger

So, I don't have to turn this into an executable file before calling it from the command line?

WidmarkRob wrote:

From the command line, I would have to type in "PracticingPassingParameters"?

Then I could just enter my two numbers and get the result?

all I really needed was four lines of code in the first place?

even when I publish this simple little program and click on the executable, it still telling me I have an out of range exception

You need to show us exactly what you have typed at the command line.
