I know many of you have used or considered using NConsole, which by all standards is a very good program, but lets say that you want to build your own interface that accepts flags with arguments. For instance if i were to use a statement like -csv "pathtofile.csv" \write the the -cvs and \write are flags of the program. I am going to show you an easy way to create this type of interface.

PS. I know the code is not optimized, it is made in a way to increase the understanding of it

Step 1: Determine Flags
My suggestion is that you take some time and write down all the flags that you want to use and what they will all do, even if you have got to the point of actually making the functions (Look At #7 Here). After detriming flags youll want to decide if those flags have something attached or not, line for instance the \write flag could have a path added to it, or you could make it default it to some location and thus wont need one. its all up to you.

Step 2: Setting Up The Interface
This CLI (Command Line Interface) is built in the main function, but you could make it anywhere you want, you would just have to pass the array of arguments on to the method

Step 2.1 : Setting Up The Main Method


That is pretty simple, its the main entry point of the program

Step 2.2 : Creating Booleans
Now this is a major, but small step. This whole design is based of one thing "booleans AKA bool " for this you wll want to create a boolean for every flag that you wanted to use. For example if i am using the flags "/help" "/write" and "-csv" then my code would look like this:



Step 2.3 : Creating The Strings
This is and isnt important dependent on your flags, for this example it is. I have decided in notepad where i listed all my flags that the -csv flag and the \write flag will have parameters attached to them so we need to store those parameters in a string.



I made them empty so that the values would be empty. Duh

Step 2.4 : Creating The ForEach Loop
This is where all the work by the interface is really done. This loop is going to take each argument one by one. Now each argument is considered to 1 word or until a space, unless its in quotes. so this is where the booleans determine if a flag is being used



Now if look at the code youll notice that everytime the flag was used it shoot up a boolean to true, then when the next argument came (the parameter) it would set it as false and set the argument equal to the string parameter_(theflag). Simple but effective. Thats pretty much the whole concept behind a "SIMPLE" CLI.

I read your tutorial and didn't really like your usage of the "flags", so I modified it a bit.
It's just another way to do it. Maybe someone will enjoy it.

Oh and, I don't know why you bothered setting the flags to false again on conditions, but I kept it around.
