❔ what is string[] args?

As title says

Denis•2/15/23, 7:32 AM

Input arguments passed into the application

Denis•2/15/23, 7:33 AM

Said arguments are passed when, e g. running a console application from the command line

SoinagieOP•2/15/23, 7:33 AM

Then why is is string [] args and not just method (some value)

Denis•2/15/23, 7:34 AM

Not sure what you are asking. string[] is an array of strings. Meaning you have multiple strings

Denis•2/15/23, 7:34 AM

Each representing an argument

DDenis Input arguments passed into the application

SoinagieOP•2/15/23, 7:34 AM

Also what application? Do you mean program?

Denis•2/15/23, 7:35 AM

Yes

SG97•2/15/23, 7:35 AM

https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/program-structure/main-command-line

Main() and command-line arguments

Learn about Main() and command-line arguments. The 'Main' method is the entry point of an executable program.

Denis•2/15/23, 7:35 AM

Either a console based application or a GUI application such as WinForms or WPF

SoinagieOP•2/15/23, 7:35 AM

Okay but i could've done it without args

SoinagieOP•2/15/23, 7:35 AM

Just string []

SoinagieOP•2/15/23, 7:35 AM

If its an argument

SG97•2/15/23, 7:35 AM

Denis•2/15/23, 7:36 AM

args is the name of the input parameter

Denis•2/15/23, 7:36 AM

You cannot ommit it

SG97•2/15/23, 7:36 AM

you can leave the parameters out completely if not needed

SoinagieOP•2/15/23, 7:36 AM

Ommit what

SoinagieOP•2/15/23, 7:36 AM

Im way too confused now

SoinagieOP•2/15/23, 7:37 AM

I have a method and put some value in it so its method (value)

SG97•2/15/23, 7:37 AM

I thought you meant the Main method

SoinagieOP•2/15/23, 7:37 AM

Main is also a method

Denis•2/15/23, 7:37 AM

When you use a method, you do indeed put a value into it

SG97•2/15/23, 7:37 AM

can you post some $code

SSG97 can you post some $code

MODiX•2/15/23, 7:37 AM

To post C# code type the following:
```cs
// code here
```

Get an example by typing $codegif$codegif in chat

If your code is too long, post it to: https://paste.mod.gg/

Denis•2/15/23, 7:38 AM

When you define a method, that can be used, you have to write it's parameters. Each parameter must have a data type and a name

Denis•2/15/23, 7:39 AM

Of course, you can have a method without parameters

Denis•2/15/23, 7:39 AM

E.g.:

SoinagieOP•2/15/23, 7:39 AM

cs 
class Car 
{
  string color = "red";

  static void Main(string[] args)
  {
    Car myObj = new Car();
    Console.WriteLine(myObj.color);
  }
}

cs 
class Car 
{
  string color = "red";

  static void Main(string[] args)
  {
    Car myObj = new Car();
    Console.WriteLine(myObj.color);
  }
}

SoinagieOP•2/15/23, 7:39 AM

Its from w3school

SG97•2/15/23, 7:39 AM

what's the issue

SoinagieOP•2/15/23, 7:40 AM

I don't know what string[] args is

SG97•2/15/23, 7:40 AM

a parameter

SoinagieOP•2/15/23, 7:40 AM

What parameter

Denis•2/15/23, 7:41 AM

A parameter for receiving command line arguments

SoinagieOP•2/15/23, 7:41 AM

Yeah I dont know what command line is

Denis•2/15/23, 7:42 AM

Ok I'll try and explain

Denis•2/15/23, 7:42 AM

Have you run a Console application yet? A black window appears with, e.g., some text

SoinagieOP•2/15/23, 7:42 AM

Yeah

Denis•2/15/23, 7:43 AM

That black window is called Command prompt in Windows. You can open it by searching command prompt

Denis•2/15/23, 7:43 AM

Or CMD for short

SoinagieOP•2/15/23, 7:43 AM

So its just input to console?

SoinagieOP•2/15/23, 7:43 AM

Command line I mean

SoinagieOP•2/15/23, 7:45 AM

I don't have my pc with me

Denis•2/15/23, 7:45 AM

And in it, you enter commands. You can call a command and specify arguments to it

Denis•2/15/23, 7:46 AM

If you'd call a c# console program a give an argument to it, you'd receive it via the args parameter

SoinagieOP•2/15/23, 7:46 AM

Couldn't you just do console.WriteLine ()
Method (console.ReadLine ())?

Denis•2/15/23, 7:46 AM

No this is something different

DDenis If you'd call a c# console program a give an argument to it, you'd receive it vi...

SoinagieOP•2/15/23, 7:47 AM

Whats args?

SSoinagie ```cs class Car { string color = "red"; static void Main(string[] args) ...

Denis•2/15/23, 7:47 AM

Here the main method is being defined, not called
