Changing IE Proxy in C#

Question

I am using FiddlerCore to write some automate test cases. THe problem which i am facing is sometimes fiddler does not shut down properly and hence the proxy remains set in IE. And the next time a test runs the pages does not load, as fiddler is closed and proxy is set. Is there a way that i can change the IE proxy through code. I want that no proxy option should be selected, as we can see when we go to Tools -> Internet options -> Connections -> LAN settings : No check box is selected. How can i achieve this using C# ? I have seen some posts on this, but nothing is specific to this requirement.

THanks!

If your app is throwing an exception and isn't shutting down properly, what makes you think that your app's code is going to be able to run? — EricLaw, Jun 19 '13 at 16:26

I assume you set up Fiddler as a system proxy by calling something similar like:

FiddlerApplication.Startup(9999, FiddlerCoreStartupFlags.Default);

When your application exits make sure to call something like:

if (FiddlerApplication.IsStarted())
{
    FiddlerApplication.oProxy.PurgeServerPipePool();
    FiddlerApplication.Shutdown();
}

to make sure your system settings get restored.
