I’ve made code to read line by line text and create a construct with informaton contained in each line. When ruuning game at unity i got error

however as I examined code i couldn’t find any mistakes, I’m still a newbie at c# so i may missed something, help please.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Text;
using System.IO;
using System.Text.RegularExpressions;

public class dialogue : MonoBehaviour
{
    public TextAsset spellData;

    struct DialoguLine
    {
        public string name;
        public string content;
        public string[] options;

        public DialoguLine(string Name, string Content)
        {
            name = Name;
            content = Content;
            options = new string[0];
        }

    }

    List<DialoguLine> lines;

    private void Start()
    {
        lines = new List<DialoguLine>();
        loadd(spellData);
    }

 
    void Update () {

    }

    void loadd(TextAsset spellData)
    {
        string fs = spellData.text;
        string[] flines = Regex.Split(fs, "\n|\r|\r\n");

        for ( int i=0; i < flines.Length; i++)
        {
            string linecontent = flines[i];
            string[] tline = Regex.Split(linecontent, ";");
            if (tline[0] == "player")
            {
                DialoguLine nextl;
                nextl.name = tline[0];
                nextl.content = "";
                nextl.options = new string[tline.Length - 1];
                for (int j = 1; j < tline.Length; j++)
                {
                    nextl.options[j - 1] = tline[j];
                }
                lines.Add(nextl);
            }
            else
            {
                DialoguLine nextl;
                nextl.name = tline[0];
                nextl.content = tline[1];  // << at this line unity get error
                nextl.options = new string[0];
                lines.Add(nextl);
            }
        }
    }

If that line is giving you an error, then there is nothing in tline[1]. Thus your array only contains 1 entry.

I would print out what linecontent is, tline.length, and then just make sure you getting the values you expect.
