✅ Reading Text in File at Position x

Hello. I would have to read the text of job_offer_data, starting with target and ending with trailer_place, from the text field. Since the text can always be somewhere different in my text field, the method with a fixed line number doesn't work. Can someone help me with that? With Contains I get up to the line job_offer_data but it's not clear to me how I can output the 13 lines from then on

Is this a school assignment or something?

Thommy•7mo ago

its for me, not for school to old for school ^^

Mayor McCheese•7mo ago

You have to know the file position to seek to, you can't really get position from line number Structured formats exist, like json, yaml, parquet, etc Some of them can be read "forward only", or a bit at a time

Thommy•7mo ago

ok, i read the file with File.ReadLines

Mayor McCheese•7mo ago

Iirc ReadLines is an enumerable?

Thommy•7mo ago

You could try to get the line number with a for loop and then read out 13 lines from there?

Mayor McCheese•7mo ago

Yeah, something like that could work But it's fragile It'll work until the format changed

Thommy•7mo ago

The format of this text block always remains the same, only the position changes

Mayor McCheese•7mo ago

So really rather than 13 lines to want to read to your next marker

Thommy•7mo ago

I'll test it tomorrow and if I get stuck, I'll let you know

Mayor McCheese•7mo ago

kk if the fields are unique you can treat them like kvp's ( key: value pairs ) and store them in a dictionary and read them to your hearts content something like....

file.ReadLines().ToDictionary(k=>k.SubString(0, k.IndexOf(':')), v=>v.SubString(v.IndexOf(':')+1)));

file.ReadLines().ToDictionary(k=>k.SubString(0, k.IndexOf(':')), v=>v.SubString(v.IndexOf(':')+1)));

you have duplicate keys though so then you're reading like a for loop like you suggested.

a sollution could be: read complete file split it into an array (on the line) Go through it with a for next or use a ling with contains

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.

Thommy•7mo ago

Ok, i found an solution!

List<string> datei = File.ReadLines(fileName).Skip(startingline).Take(readlines).ToList();

List<string> datei = File.ReadLines(fileName).Skip(startingline).Take(readlines).ToList();

it read the lines at startingline and read 'readlines' from the file and take it to an List string
