Why does this not work? [Answered]

Hey, pretty new to coding and trying some things out, someone knows why it says that my var "randomNumber" is not in the context?

using System;

namespace Awesome_Program
{
    class Program
    {
        static void Main(string[] args)
        {
            Typewriter("Hello... Wizard!");
        }

        public static int NumberGen()
        {
            Random numberGen = new Random();
            int number = numberGen.Next(50,300); 
        }

        public static void Typewriter(string word)
        {
           for (int i = 0; i < word.Length; i++)
           {
                Console.Write(word[i]);
                int randomNumber = NumberGen();
                System.Threading.Thread.Sleep(randomNumber);
           } 
        }
    }
}

using System;

namespace Awesome_Program
{
    class Program
    {
        static void Main(string[] args)
        {
            Typewriter("Hello... Wizard!");
        }

        public static int NumberGen()
        {
            Random numberGen = new Random();
            int number = numberGen.Next(50,300); 
        }

        public static void Typewriter(string word)
        {
           for (int i = 0; i < word.Length; i++)
           {
                Console.Write(word[i]);
                int randomNumber = NumberGen();
                System.Threading.Thread.Sleep(randomNumber);
           } 
        }
    }
}

randomNumber = NumberGen; tries to assign a new value to an existing variable. However the variable randomNumber was never declared, so it doesn't exist at that point. I think you probably meant int randomNumber = NumberGen(); (You also need to call the NumberGen method, by putting () after the method name)

ahh i see okay i changed it, but now it says that it doesnt get a return value

you don't return the number that's generated in NumberGen()

Ohhh i understand so basically NumberGen has no var until i use return number; right?

Anu6is•3y ago

right, it has no value until you actually return something in your case, yes number
