Switch Statement with Strings C#

I need to write something that will get the start-up arguments and then do something for those start-up args, and I was thinking that switch would be good but it only accepts for ints and it has to be for a string

This isn't the actual code but I want to know how to make something like this work

namespace Simtho
{
    class Program
    {
        static void Main(string[] args)
        {
            switch (Environment.GetCommandLineArgs())
            {

                case "-i":
                    Console.WriteLine("Command Executed Successfully");
                    Console.Read;
                    break;
            }
        }

    }
}

Environment.GetCommandLineArgs() returns an array of strings. Arrays cannot be switched on. Try iterating over the members of the array, like this:

namespace Simtho
{
    class Program
    {
        static void Main(string[] args)
        {
            foreach (string arg in Environment.GetCommandLineArgs())
            {
                switch (arg)
                {

                    case "-i":
                        Console.WriteLine("Command Executed Successfully");
                        Console.Read();
                        break;
                }
            }
        }
    }
}

Environment.GetCommandLineArgs() returns a string[]

You can't switch on a string array. You probably want to test if the array contains certain values though.

Environment.GetCommandLineArgs() returns array of strings?

And maybe i'm wrong but internally switch on strings converted to if-else sequence...

What about something like this?

string[] args = Environment.GetCommandLineArgs();

if (args.Contains("-i"))
{
    // Do something
}
