[RESOLVED] Readline help?

Hi folks

Im writing a small database program, mainle for the practice, and ive run into a problem, that i cant really solve.

The situation is that i want to start from line 1 of my database (a .txt database), then skip all line until i reach a semicolon ( ; ), then read the line below that semicolon, then skip until the next semicolon, and read the line below that one. I believe you get the picture.

Ive tried to create another, small database, containing information about where all semicolons were, but this seemed clumsy, and like a very bad way of doing it.

All help is greatly appeciated :)

if this is the format of your .txt file:

Code:

---

line1
some text;
some more text
event more text;
more more more

---

then this might be what you want:

Code:

---

    string[] lines = File.ReadAllLines(@"C:\myfile.txt");
    bool printline = false;
    foreach(string line in lines)
    {
        if(printline)
        {
            Console.WriteLine(line);
            printline = false;
        }
        if(line.EndsWith(";"))
            printline= true;
    }

---

this produces this output:

Code:

---

some more text
more more more

---

Actually, the semicolons are on a seperate line, but that solution you have there actually seems very good. Thanks a lot ! :)

wouldn't that code not print the first line if it had a semicolon and instead it would print the second line?

Form your first post...

yep, that's what he wanted ;)

turns out the syntax for his file is this:

Code:

---

line1
some text
;
some more text
even more text
;
more more more

---

this will result in the same output, but if this was the file:

Code:

---

;
line1
some text
;
some more text
even more text
;
more more more

---

line1 would be printed too
