❔ Adding to Arrays Via Methods

I am having trouble getting arrays to be changed by methods. I tried lists as well. Please send help.

Angius2/6/2023

You can't append items to arrays

Angius2/6/2023

They're fixed-size

Angius2/6/2023

Use a List<T>

HumNumWorld2/6/2023

string[] plants = {};

createPlant(ref plants);
createPlant(ref plants);
createPlant(ref plants);
Console.WriteLine(plants[0] + plants[1]);
Console.ReadLine();
// avolva aventine  
static void createPlant(ref string[] plants)
{
    Console.WriteLine("What is the Name of your Plant?");
    plants = new string[] { Console.ReadLine() };
    Console.Write("Completed! Push any Button to Exit.");
    Console.ReadLine();
    //may just have to for now.
    string print = ""; 
    for (int i = 0; i < plants.Length; i++) 
    {
        Console.Write(plants[i] + ", ");
    }
    Console.WriteLine(print);
    Console.ReadLine();
}

@85903769203642368 thanks but look at this

HumNumWorld2/6/2023

its error after error

Angius2/6/2023

The parameter is declared as a string[], so obviously it won't take a List<string>

Angius2/6/2023

Also, in your CreatePlant() method you crate a brand new array

Angius2/6/2023

You don't add anything, you replace

HumNumWorld2/6/2023

can you explain that

Angius2/6/2023

What's to explain there?

Angius2/6/2023

Square peg doesn't fit into a round hole

Angius2/6/2023

int and string are different types

Angius2/6/2023

So are boolean and UngaBunga

HumNumWorld2/6/2023

where is the square peg

Angius2/6/2023

So are string[] and List<string>

Angius2/6/2023

List<string> is the square peg

Angius2/6/2023

The method has a round hole, string[] type parameter

Angius2/6/2023

List<T> is not T[]

HumNumWorld2/6/2023

oh ignore the writeline

Angius2/6/2023

Nothing to do with any writeline

HumNumWorld2/6/2023

right here where is the []

HumNumWorld2/6/2023

and ignore line 27 for now

HumNumWorld2/6/2023

im just trying to get the errors off the first part until it functions

Angius2/6/2023

Aight, so, why do you try to pass ref List<string> plants as a parameter?

Angius2/6/2023

Do you also use Console.WriteLine(string "message")?

HumNumWorld2/6/2023

apparently to change a variable in a function you have to use ref

HumNumWorld2/6/2023

I tried just "plants" but it said it has to be written like a list

Angius2/6/2023

Yeah, in the parameter declaration

HumNumWorld2/6/2023

was there a better way of doing that

Angius2/6/2023

When you call the method, you don't supply a type

Angius2/6/2023

You just pass the param

HumNumWorld2/6/2023

wym

Angius2/6/2023

CreatePlant(plants)

HumNumWorld2/6/2023

like this?

Angius2/6/2023

Not here

Angius2/6/2023

Jesus

Angius2/6/2023

$helloworld

HumNumWorld2/6/2023

im used to javascript

Angius2/6/2023

You really should brush up the basics

HumNumWorld2/6/2023

its much easier when I could do something like:

appendItem("plants", "");

HumNumWorld2/6/2023

which I dont even know if thats a real thing

Angius2/6/2023

And you can

HumNumWorld2/6/2023

because I learned from code.org

Angius2/6/2023

var plants = new List<string>();
plants.Add("carrot");
plants.Add("hydrangea");
plants.Add("juniper");
