C# integer from text file

Lars Nilsson

Hey guys,

Im new here and I need your help, please.

Im working on something that uses the Paint event in Visual C# 2010, and I need to draw a rectangle. The rectangle can only be drawn by integer values in it,
and I got these integer values in a text file. So what I need to do is to read the integer from either row 2 or row 3 in the text file and assign that value to an integer in the program.
How can I do that?

I heard something about Console.ReadLine(); but it just works with strings, also I tried Console.Read(); which just read one character (i guess) without that I specified what line it should
read from. Im kind of confused.

Please help.

By the way, I use framework 2.0 as goal, so all my friends can try the program later.

- Lars.

I got it working now, I made an integer variable which = Convert.to32 and then I loaded it in there but before that I had an if statement containing if(File.exists("file.txt")
so if it existed it converted the string to and integer. Hard to explain but anyways. Thanks!

Are the integers in the format of text digits or are they binary integers? Probably text. Do you need to show the integers the same way that they appear in the file? You say that Console.ReadLine() only works with strings but it is very unclear what you need to do.
