HI , I am developing a small application in which C# reads a file make changes to it and saves it. The txt files contains dome configuration values say TimeOut=30 ID=abcd Scope=Allowed . . . 1.In my screen i also want to show these values, so what is the method to fetch individual values 2.When i make any change to the value i want it to be saved in that particular line itself. Thanks in Advance.

Why are you using an ini file and not XML ?

I'm not saying that INI files are the be all and end all of config files, but they are a *lot* easier for novice users to edit, compared to XML files.

Cheers, Vikram.

You can read the values into a dictionary like this:

Dictionary<string, string> values = new Dictionary<string, string>();
foreach (string line in File.ReadAllLines(fileName)) {
string[] data = line.Split('=');
if (data.Length == 2) values.Add(data[0], data[1]);
}

To read a value from the dictionary:

string id = values["ID"];

Files are not line based, so you can't change a single line in a file. It's possible to update the file from that line and forward, but it's complicated. Just rewrite the entire file.

Despite everything, the person most likely to be fooling you next is yourself.
