If you are using a console application, the main method woould have a string array as a parameter that would contain all the parameters.

E.g. The code below displays all the command line arguments.

class TestClass
{
    static void Main(string[] args)
    {
        // Display the number of command line arguments:
        System.Console.WriteLine(args.Length);
    }
}

The arguments to Main are the command line arguments. If you're using the standard Visual Studio template, you can find the Main method in Program.cs. If I need them in a Windows application I generally modify that Main method to pass the array of arguments into the main form's constructor, and handle them in there.

Ralphlee1's answer is also correct but I prefer to pass them as arguments from the single entry point because that seems cleaner, as the external information is only being fed in in a single place.
