I want to replace a line inside the Preferences file of Google Chrome in order to change current homepage.
In my computer, i've http://www.google.com which is defined as a default homepage, and therefor i need to replace (inside the Preferences file) the following line :
"homepage": "http://www.google.com/",
Replace with :
"homepage": "http://www.MyWebsite.com/",
So in order to do this, i am using a code which look something like this :
string PreferencesFile = File.ReadAllText(file);
PreferencesFile.Replace(FirstLine,SecondLine);
File.WriteAllText(file,PreferencesFile);
But the problem is that in each computer, there is a different homepage.
How to replace the line below
"homepage": "http://www.what-ever-site-is-here.com/",
With
"homepage": "http://www.MyWebsite.com/",
And which values should be affected to FirstLine and SecondLine variable ?

Sounds like you should read all the lines, replace any line starting with "homepage":
and then rewrite. For example:
var lines = File.ReadAllLines(file);
for (int i = 0; i < lines.Length; i++)
{
if (lines[i].StartsWith("\"homepage\": "))
{
lines[i] = "\"homepage\": \"http://www.MyWebsite.com\"",";
}
}
File.WriteAllLines(file, lines);
