✅ System.FormatException: 'Input string was not in a correct format.'

Hello, I am trying to make a Winform Program that takes in a text file, turns it into a string in a generated array textbox, and then sorts the array in another textbox called sort values. However, it seems like I am having some issues parsing my string. Can someone help me here? Here is the link to my code: https://paste.mod.gg/aarnffywcwsx/0

Where exactly is that exception thrown? On the int[] values = Array.ConvertAll(lines, int.Parse);?

Yes

It means one of the values is not a valid integer, then

Hmmm that’s not right Should I send my text file or something? Or a screenshot of what’s going on? Gimme a sec, I went to sleep after I posted this so I am just seeing all of this now

A bit curious, why would you do that? Why ask for help as you become available, instead of when you are available? Almost always, we will have to ask questions to provide help.

Because from my experience it takes a while in order to actually get help And sometimes the time zones can be very different whenever I ask questions Whenever I ask these questions it could be in the middle of the night And I haven’t gotten actual sleep cuz I have been going at a problem so too many hours on my own

I'd say 80-90% of well asked questions get some form of interaction within 30 minutes or so anyways, show the file

ok see look at your code

 // Read all lines from the text file
string[] lines = File.ReadAllLines(fname);

// Convert lines to integers
int[] values = Array.ConvertAll(lines, int.Parse);

 // Read all lines from the text file
string[] lines = File.ReadAllLines(fname);

// Convert lines to integers
int[] values = Array.ConvertAll(lines, int.Parse);
