Examples

The following example shows how to use the GetWriteLock method when you add a route while the application is running.

Remarks

The recommended approach for defining routes in an ASP.NET application is to add the routes to the Routes property in an event handler for the Application_Start event in the Global.asax file. For more information, see RouteCollection.

If you have to add a route when the application is running, you use the GetWriteLock method to guarantee thread safety. The write lock on the route collection is released when the IDisposable object that is returned by this method is disposed.
