It always has 2 lines of breaks between each block. I would like to put those blocks into an object that I create.

string[] test = File.ReadAllLines(file);
foreach (var s in test) {

}

How can I approach it the proper way? Normally I would go by foreach line and try to split the blocks by empty 2 lines then go further by doing multiple if/else statements. But maybe there's simple/better approach to this?

Answer 1

string[] blocks = (file.ReadAllText(file)).split(new string[] {"\n\n\n"}, StringSplitOptions.None)

Should break it into blocks for you.

Answer 2

Look at using StreamReader and use your logic to find what you are looking for.

StreamReader _sr = new StreamReader("YourFile");
_sr.ReadLine();
