Disposing Browser instance
When you don't need to use Browser instance you must dispose it using Browser.Dispose() method. For example:
browser.Dispose();
Disposing BrowserView instance
It is necessary to disposeBrowserView in your code if that BrowserViewwas created via its non-default constructor.
For theBrowserView, you need to dispose the view first and its browser second:
browserView.Dispose(); browserView.Browser.Dispose();
The usual place to disposeBrowserView isFormClosing event for WinForms andWindow.Closing event for WPF.
If the BrowserView is instantiated using the default constructor, it creates a Browser instance inside itself. In this case, theBrowserView is considered as the owner of this browser instance, and that Browser instance will be disposed with the view when the BrowserView.Dispose() is called for it.
In addition, such view will be disposed automatically when the form or window that contains it is closed - this behavior is designed to simplify proper shutdown process for the case when the BrowserView is used as a regular control.
Disposing BrowserContext instance
If you have manually created the BrowserContext instance, then it is recommended to dispose it using the BrowserContext.Dispose() method when you no longer need it. This should be done after all the Browser and BrowserView instances using this context were disposed. For example:
browser.Dispose(); browser.Context.Dispose();
Accessing disposed instance
Once you disposed the Browser instance, you cannot use it anymore. If you try to access already disposed Browser instance theObjectDisposedException exception will be thrown. For example:
browser.Dispose(); var title = browser.Title; // ObjectDisposedException will be thrown
To check if Browser instance is disposed or not, you can use Browser.IsDisposed() method.
Dispose Events
Each Browser instance can be also disposed from JavaScript via window.close() function. In this case, you might be interested in receiving notification when Browser instance is disposed. To get such notifications, you can use event handler. For example:
browser.DisposeEvent += delegate(object sender, DisposeEventArgs e)
{
// Browser is disposed
};When you dispose Browser instance manually via Browser.Dispose() method, the Dispose event will also be fired.
