Hello to evreyone i am using Visual Studio 2008 for native program project.

I am using StreamReader and StreamWriter to read and write to file my question is, how can i replace a line with new value without change line.

e.g myfile.txt
blue
red
yellow

and to change to
green
red
yellow

The value is not the same but i want to replace and not to delete and writer new because is organized by ID!
Thank you

First you need to read the contents of the file line by line. Then if it contains a certain text replace it with your new text.

ReadFileByLine
If Line.Contains("Blue")
Line = Line.Replace("Blue", "Green")

The above code is obviously not a working example but I hope you get the point. :)
