Question

So this is just a thought… Say I wanted to insert a line into a file at the first linebreak, but I didn’t want to read the entire file into memory. Is there a way to just read the file into memory line by line and then, when the first linebreak is reached, insert a line and close the file reader?

Thank you!

Sorry for the earlier typo in my title/description

Answer 1

you can read one byte at a time and intercept the line break character. Then at that position do a stream.WriteLine(). You’ll hve to open file for read+write

Edit: I thought of using the FileStream object, but I’m not sure. Any for now try the suggestion mentioned here: http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/e5077949-5d23-4d26-a530-6d503745a197
