How do I print each element of a string array separately to a UI text box

[TheIrishKraken]

I am creating a game which involves a chat room.
I want to store an array of strings which are basically dialogues from 2 characters.
Every time I press Space bar I want to print each dialogue separately one after another.
I feel like I am close but I cant figure out how to print induvial elements from the array, all I was able to do was print all elements at once which I don’t want.
Any help would be really great, thanks.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using TMPro;

public class DialogueManager : MonoBehaviour
{
public TextMeshProUGUI dialogueText;

[TextArea(3, 10)]
public string[] sentences;

protected void Update()
{
    if (Input.GetKeyDown(KeyCode.Space))
    {
        StartDialogue();
    }
}

public void StartDialogue()
{
    foreach (string sentence in sentences)
    {
        ???????
    }
}

}

You need to access each array element separately.

Here’s a solution with looping dialogue:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using TMPro;

public class DialogueManager : MonoBehaviour 
{ 
	private int sentenceIndex;
	public TextMeshProUGUI dialogueText;

	[TextArea(3, 10)]
	public string[] sentences;
	protected void Update()
	{
		if (Input.GetKeyDown(KeyCode.Space))
		{
			StartDialogue();
		}
	}
	public void StartDialogue()
	{
		sentenceIndex = (sentenceIndex + 1) % sentences.Length;
		dialogueText.SetText(sentences[sentenceIndex]);
	}
}

Hi

Thank you so much for your answer.
I applied your solution but I get this error every time I hit space.
