ive got to about here so far but also have no idea how to read each line and move onto the next and idk how to make each line an array so the split array can split the lines into an array

Just so you know, File.ReadAllLinesAsync() will just read the file lines into a string[] No need for this whole song and dance with streamreader You will, then, need to parse each line you have The format seems to be owner:[dog:color,dog:color] so it should be fairly easy to parse Split on : first to get an array of [ owner, dogs ] then trim [ and ] from dogs and split on , Then split each dog on : to get [dog, color] Ideally, you're looking to parse the file into something like List<Person> where

class Person
{
    public string Name { get; set; }
    public Dictionary<string, string> Dogs { get; set; }
}

class Person
{
    public string Name { get; set; }
    public Dictionary<string, string> Dogs { get; set; }
}

class Person
{
    public string Name { get; set; }
    public List<Dog> Dogs { get; set; }
}
class Dog
{
    public string Name { get; set; }
    public string CollarColor { get; set; }
}

class Person
{
    public string Name { get; set; }
    public List<Dog> Dogs { get; set; }
}
class Dog
{
    public string Name { get; set; }
    public string CollarColor { get; set; }
}

Oh, and to loop over all the lines... use a loop foreach will work just fine To split a line you use... .Split() With a delimiter, of course. For example:

var line = "Billy Bob:Rex";
line.Split(':')

var line = "Billy Bob:Rex";
line.Split(':')

Result: string[]

[
  "Billy Bob",
  "Rex"
]

[
  "Billy Bob",
  "Rex"
]

Huh, now that I look at the format, just splitting on : won't be sufficient, since it will split all the dogs as well... Writing a quick parser would probably be the best, something like...

REPL Result: Success

var line = "Billy Bob:[Rex:Red,Fluffy:Green]";

var person = "";
var dogs = "";
var parsingDogs = false;
foreach (var ch in line)
{
    if (ch == ':') parsingDogs = true;
    if (parsingDogs) dogs += ch;
    else person += ch;
}

new { person, dogs }

var line = "Billy Bob:[Rex:Red,Fluffy:Green]";

var person = "";
var dogs = "";
var parsingDogs = false;
foreach (var ch in line)
{
    if (ch == ':') parsingDogs = true;
    if (parsingDogs) dogs += ch;
    else person += ch;
}

new { person, dogs }

Result: <>f__AnonymousType0#1<string, string>

{
  "person": "Billy Bob",
  "dogs": ":[Rex:Red,Fluffy:Green]"
}

{
  "person": "Billy Bob",
  "dogs": ":[Rex:Red,Fluffy:Green]"
