✅ .Split() Returning Spaces Between Words in String[]

Hi. I have an string array string[] strArr of words in format [word1, word2] and so on - just a basic format.. I got that by performing .Split() on another string, let's say string x. x was in format

"""
word1
word2
"""

"""
word1
word2
"""

and so on, for 30,000 lines. Now that I've converted this all to an array, how can I print the array such that the Console output would be ["word1", "word2"] etc.? I want to initialize strArr instead of performing .Split() everytime my app starts.

Please ping if you reply 🙂

Split it, then serialize it as JSON and you'll get the desired format

AdiZ•7mo ago

Serializing as JSON = something I've never heard of. Is it easy to figure out from a quick Google?

Angius•7mo ago

using System.Text.Json namespace, JsonSerializer.Serialize(the_data) Ez

AdiZ•7mo ago

And where does it get stored?

Angius•7mo ago

In... the variable you assign it to? It returns a string Formatted as Json How you handle it is up to you

AdiZ•7mo ago

Ok cool I'll go do that real quick Was looking at an instructional page and it was talking about opening writing and closing files so I was thinking of that 😁

Angius•7mo ago

Json files are commonly used to store data, so that's probably why But serialization alone will only return a string

AdiZ•7mo ago

Ok so that worked excellently, but I'm having a weird issue with .Split().

Grabbing from this list, I'm just using .Split() to separate into a string[] of all the words as they're just separated by lines. But I'm getting "keen","","flyer","","peas","","dosage","","receivers", i.e. with spaces in between. Why could this be happening?

Angius•7mo ago

What's your full code? The splitting and all

AdiZ•7mo ago

using System.Text.Json;

string originalStr = """
arbor
mediawiki
configurations
poison
""";
Console.WriteLine(JsonSerializer.Serialize(originalStr.Split()));

using System.Text.Json;

string originalStr = """
arbor
mediawiki
configurations
poison
""";
Console.WriteLine(JsonSerializer.Serialize(originalStr.Split()));

Obviously originalStr here is a sample size, but I used all 10k words for the real thing (though that doesn't matter). Let's actually try this

REPL Result: Success

using System.Text.Json;

string originalStr = """
arbor
mediawiki
configurations
poison
""";
Console.WriteLine(JsonSerializer.Serialize(originalStr.Split()));

using System.Text.Json;

string originalStr = """
arbor
mediawiki
configurations
poison
""";
Console.WriteLine(JsonSerializer.Serialize(originalStr.Split()));

Console Output

["arbor","mediawiki","configurations","poison"]

["arbor","mediawiki","configurations","poison"]

huh That's very weird

AdiZ•7mo ago

This is the full code that I have.

Angius•7mo ago

Could be a system-dependent issue

AdiZ•7mo ago

Oh nvm it caps out anyway Just installed C# on VSCode

Angius•7mo ago

Linux — which the bot runs on — uses \n for line ends Windows uses \n\r Idk ¯\_(ツ)_/¯ Oh Right And both are whitespace, so that's what .Split() splits on by default word\n\r gets split by whitespace into word, empty string

AdiZ•7mo ago

So do I just change it to .Split('\n')?

Angius•7mo ago

You could always filter the strings Or split exactly by \n or by "\n", "\n\r"

AdiZ•7mo ago

Interesting... "liechtenstein\r","mating\r","compute\r","redhead\r","arrives\r" is what I get when I do

originalStr.Split("\n")

originalStr.Split("\n")

Angius•7mo ago

Yeah, so try .Split("\n", "\n\r")

AdiZ•7mo ago

Are you sure? Just throws error CS1503: Argument 1: cannot convert from 'string' to 'char' Argument 2: cannot convert from 'string' to 'int' I did exactly this originalStr.Split("\r\n") This worked perfectly. I don't claim to have a clue what's going on Ohh carriage returns I've done those before Makes sense Thanks @ZZZZZZZZZZZZZZZZZZZZZZZZZ

Angius•7mo ago

Now you'll have issues on systems that don't use carriage return 😛

AdiZ•7mo ago

Ah well I got my JSON, that's all I care about xD What would I do if I couldn't use \r? @ZZZZZZZZZZZZZZZZZZZZZZZZZ Now I've got string[] tenKMostCommonWords = new String["the","of","and","to"..."poison"]; And on the character before the " at the start of poison, Unity gives me Assets\Scripts\ListConstants.cs(7,95926): error CS0029: Cannot implicitly convert type 'string' to 'int'

Angius•7mo ago

Split by \n and .Trim() each element, that'd probably be the easiest and most x-plat way

AdiZ•7mo ago

But I feel like I'm initializing that string[] wrong

Angius•7mo ago

Uh, yes That's not how you initialize an array

AdiZ•7mo ago

Sorry I shouldn't be asking here I can definitely find this in the docs

Angius•7mo ago

string[] foo = new[]{ "abc", "def", "ghi" };

string[] foo = new[]{ "abc", "def", "ghi" };

AdiZ•7mo ago

Oh you have to initialize it first? That can't be right

Angius•7mo ago

Could even omit new[] really

AdiZ•7mo ago

Yeah ok never mind How are you using {}? I thought it had to be []?

Angius•7mo ago

Nope [] denotes the array It can contain an integer for size var foo = new int[6]() will create a new int array of size 6 for example

AdiZ•7mo ago

Ah that's interesting Got it

Angius•7mo ago

var foo = new int[6, 7](); will make a new 2D array of size 6x7 That's why it was complaining about not being able to treat a string as an int

AdiZ•7mo ago

Ohhh I was wondering How many dimensions can an array have?

Angius•7mo ago

For initialization, you use {}

var person = new Person {
    Name = "Bob",
    Age = 67
};
var data = new Dictionary<string, int>() {
    ["one"] = 1,
    ["two"] = 2,
};

var person = new Person {
    Name = "Bob",
    Age = 67
};
var data = new Dictionary<string, int>() {
    ["one"] = 1,
    ["two"] = 2,
};

etc Not sure if there's a limit There probably is, but something like 256 or some such

AdiZ•7mo ago

Apparently 32 Makes sense 32-bit Alright thank you so much mate I think you've answered every question I've asked here to date What would I do without ya 🤣 Much appreciated 👍
