Pick a random string from a string array C#

[Caruzo]

Hello,

I know that this has probably been asked many times but I spent 1 hour to find a solution in the web about it but to no avail.

I have a string array with 4 strings inside, then I created a function that says: if something.text equals “Africa” make userCountry.text equal to a randomly picked string from this specific string array, FOR MORE CLARIFICATION check the image below:

However, the assembly tells me that userCountry[…] is not valid expression in this context. So my question is how to link it to this specific array!

→ I know how to make it random

Any help will be appreciated

Don’t do stuff with floats when indexing (and it should be FloorToInt) when you can use integers.

Here’s an example that uses a nice extension method to get a random item from an array.

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        string[] fruits = { "Apple", "Banana", "Orange" };

        print(fruits.RandomItem());
        print(fruits.RandomItem());
        print(fruits.RandomItem());
        print(fruits.RandomItem());
        print(fruits.RandomItem());
    }
}

public static class ArrayExtensions
{
    // This is an extension method. RandomItem() will now exist on all arrays.
    public static T RandomItem<T>(this T[] array)
    {
        return array[Random.Range(0, array.Length)];
    }
}
