indicates the time at which the signal was raised this can differ from when the signal is received. The additional flexibility available when working with a System.Timers.Timer comes from the way that these timers can be stopped and started and also from their AutoReset property, which allows an instance of this timer to represent an event that should be repeated or should no longer be fired. Because the timer instance is passed into the event handler, this can be controlled on the fly. In addition, being aware of which timer has raised a signal is better suited to complex code, which can maintain a number of timers. Since this class raises signals via events, multiple handlers can be attached to a single timer, although we advise caution if attempting to modify the timer settings since the other listeners may then produce unexpected results. This is the timer class that we tend to use when defining systemwide events, such as the start of a batch process or rolling log files. By having all actions that should occur together tied to a single timer, we can vary the period between actions in a single place and have the effect propagate through the code seamlessly. For other tasks, we favor System.Threading.Timer.

The newobj IL instruction constructs a new instance of an object . However, no newobj instruction appears in the IL code example . Instead, you see the special ldstr (load string) IL instruction, which constructs a String object by using a literal string obtained from metadata . This shows you that the common language runtime (CLR) does, in fact, have a special way of constructing literal String objects . If you are using unsafe code, you can construct a String object from a Char* or SByte* . To accomplish this, you would use C# s new operator and call one of the constructors provided by the String type that takes Char* or SByte* parameters . These constructors create a String object, initializing the string from an array of Char instances or signed bytes . The other constructors don t have any pointer parameters and can be called using safe (verifiable) code written in any managed programming language .

4. Your main office is connected to a branch office through demand-dial routing. Each router is configured to call or answer the call of the other router as needed. However, the Finance Department has asked you to ensure that telephone con nection charges between demand-dial routers be predominantly incurred by the main office. How can you achieve this goal

While this may seem to be a strange concept, it means that you do not need to hold onto a reference to the container after you perform this initial population of dependencies. That doesn t mean you cannot hold onto the container reference as well, but resolving all of the required types at startup can improve run-time performance at the cost of slightly increased startup time. Of course, this also requires additional memory and resources to hold all of the resolved instances, and you must balance this against the expected improvement in run-time performance. You can populate all of your dependencies by resolving the main form or startup class through the container. The container will automatically create the appropriate instances of the objects required by each class and inject them into the parameters and properties. However, it does rely on the container being able to create and return instances of types that are not registered in the container. The Unity container can do this. If you use an alternative container, you may need to preregister all of the types in your application, including the main form or startup class. Typically, this approach to populating an entire application object graph is best suited to applications built using form-based or window-based technologies such as Windows Presentation Foundation (WPF), Windows Forms, console applications, and Microsoft Silverlight (using the version of Unity specifically designed for use in Silverlight applications). For information about how you can resolve the main form, window, or startup class of your application, together with example code, see the documentation installed with Enterprise Library or available online at http://go.microsoft.com/fwlink/ LinkId=188874.
