Execute a C# console application with parameters in command prompt

I am currently writing a console application that deletes old log files, now I got that functionality working, I was trying to figure out how to execute a program with parameters from Command Prompt.

Example: 

FileDeleter.exe days 3

where I'm running the program and telling it to delete 3 days worth of log files. Can these arguments be passed as variables into the code? I am not sure how this is accomplished.

Thanks for the help!

If you need more advanced parsing, there are of course libraries available Best way to parse command line arguments in C#?

As @Neil N already mentionend, you have to define a your main method like this:

static void Main(string[] args)

args will then contain the arguments you passed.

If you run your program like this: FileDeleter.exe days 3, args[0] would contain the string "days" and args[1] would contain the string "3". Pay attention here that the latter one will be a string despite the fact that you passed a number. Therefor you might have to parse it to a number before using it.

your void main should take an array of strings as an arg:

static void Main(string[] args)

You can then parse the args as you see fit.
