Title: Reading from a file to return a string[] array
Post by: Mr Feltzer on September 08, 2013, 08:23:21 am

Hello, I have been working on a new bunch of systems and the documentation on the file reader is horrible.

IS there ANY way to read from a file and return every Line as a string within an Array?

Thanks lads, Good day.

In C# you can read the entire contents of the file in a string, then split the string using a delimiter ('\n')

Ah yes. Good Thinking haha

Edit:
Bastard Error my friend.

Code: [Select]

string filestring;
if(filestring[i] == "\n") // This returns Error: "No conversion from 'string@&' to 'uint' available." Even though I am simply gathering a string with an index. @_@

Any ideas? I have worked with strings before and have never seen this issue.

Just read what the error says, you're comparing a uint (wide char filestring[ i ]) with a string ("\n"), it's like comparing carrots and apples.

You can also split strings in angelcode using one of these:

Code: [Select]

string[]  split (const string& in str, const string& in delimiter)
  Splits the string into an array of substrings.
 
string[]  splitEx (const string& in str, const string& in delimiter)
  Splits the specified string by string, using the specified separator.

Excellent! that did the trick!

@k3tamina
In all my previous experiences with C#, an Index on a string locates a char or part of the string.
example
string lestring = "hax";
lestring[0] would be h

Obviously Angel has changed a tad more than I expected.
