Splitting text into strings - Kαѕρer - Jul 13, 2017

If I have a .txt file with this for example:

username1:password1
username2:password2
username3:password3

How am I able to load first username1 into the "username" string and password2 into the "password" string? And then once that's done by logging in, going back to the login screen and then loading username2 in the "username" string and password2 in the "password" string?

string Accounts = File.ReadAllText("C:\\file.txt");

I tried this but then I end up getting all the accounts in that string and that's not how I want it.

I know this sounds confusing, but I can't explain it better. I hope someone can help me out.

Thanks!

File.ReadLines/ReadAllLines() and string.Split() function. It's not confusing at all and pretty simple to do.

Yeah, but how can I make from the part before the ":" a string and from the part after it another string?

Code 
List<string[2]> accounts = new List<string[2]>();

List<string> file = File.ReadAllLines("C:\\file.txt").ToList();

foreach (int line in file) : accounts.Append(line.Split(":", StringSplitOptions.None);

Might work, might not. But you get the idea.

If you really "knew" you would have been able to comprehend that I gave you the solution. I already answered this question...

You find your way to get a string, line for line, then you use this:

string username = line.Split(':')[0];
string password = line.Split(':')[1];

protip: You won't just call .Split() once. It would be easy to spoonfeed code, but trust me, it makes it a pain in the ass to learn later on.

Go in Google.com and search how you can read a TXT FIle.

Then search how does String.Split function works.

And then figure out by your self .

What if the password contains a :?

OP, use SubString and IndexOf.

This should work too.

Code 
string[] split = line.Split(new char[] { ':' }, 2);

Split still works as shown..

Mmmmmmmm. Forgot about that overload of String.Split. Good one bud!

And in the instance I quoted, under the circumstances I stated, would return an inaccurate password. Bah's solution is accurate. Other dudes was not.

In that context it seemed like you were suggesting to use the methods Substring() and IndexOf() over Split() entirely for the one reason you mentioned, and didn't suggest the alternative overload of IndexOf() at all. In that context it seemed like you were blaming the Split() function. People who mentioned the function could have been correct, it was just that one snippet that was not.

And my analysis of your post appears to be correct too:

Quote:Forgot about that overload of String.Split. Good one bud!

I wasn't saying that his snippet with Split() was right, I was saying that Split() still works if used properly, which is still a true statement regardless of the context of your post.
