How to erase line from hosts file?

kishan gajjar

HI...

I am developing 1 little application to block website.
I am able to block websites by adding websites name into c:/windows/system32/drivers/etc/hosts file.

 string path=@"c:\windows\system32\drivers\etc\hosts";

streamwriter sw=new streamwriter(path,true);

sw.writeline("127.0.0.1 www.google.com");

sw.close();

Its working great.
But now i want to unblock blocked website.so i have to delete that specific line from hosts file.

So can u please tell me how to erase line from this hosts file.???

Please reply me soon.I am waiting.

Thanx in advance.

Hi! Try this

        string text = File.ReadAllText(@"C:\host.file");
        text.Replace("127.0.0.1 www.google.com", string.Empty);
        File.WriteAllLines(@"C:\host.file", new[] { text });
