Question

So I have this switch in order to set a wait time

public int Option(string arg)
{
    switch (arg)
    {
        case "/t:Max":
                return 0;
        case "/t:Med":
                return 1000;
        case "/t:Min":
               return 2000;
        default: return 0;
    }
}

How can I use enum for /t:Min, /t:Med, /t.Max in order to replace the switch?

Indeed something like:

enum t
{
    /t:Min,
    /t:Med,
    /t:Max
};

Your enumeration should be like this:

public enum WaitTime 
{
     Min, Max, Med
}

and convert your switch to this:

switch ((WaitTime)Enum.Parse(typeof(WaitTime), arg.Replace("/:", string.Empty)))
{
    case WaitTime.Max:
            return 0;
    case WaitTime.Med:
            return 1000;
    case WaitTime.Min:
           return 2000;
    default:
           return 0;
}
