The Task class is responsible for managing background threads. To use the Task class, all you have to do is create a Task object, register the events that it fires, and implement the handling for these events. Because the events are fired on the UI thread, you don t need to worry about threading issues at all in your code. The following example shows a Task object being created. In this example, the UI has two buttons, one for starting the calculation and one for stopping the calculation, and a progress bar that shows the current calculation progress.

The first thing that we need to do to produce our desired output is select the .NET category element within our XML. The Element axis method allows us to select a single XML element by name. In our case, we re looking to select the first XML element with the category name. We can use listing 10.2 to do just that.

XElement root = XElement.Load("categorizedBooks.xml"); XElement dotNetCategory = root.Element("category"); Console.WriteLine(dotNetCategory);

As you can see, we start by loading our XML into an XElement using the static Load method we introduced in chapter 9. Once we have our XML loaded, we call the Element axis method on the root XElement and pass category as a parameter. The Element axis method accepts an XName as a parameter and returns the first matching XElement with the provided name that is a child of the current element. As we learned in the previous chapter, the implicit operator overloads defined on XName allow us to pass category instead of new XName("category"). The implicit operator overload automatically turns the string "category" into a full XName object with the local name set to category. The code in listing 10.2 results in the following output being printed to the console:

// Create new task object to manage the calculation. _calculationTask = new CalculationTask(); // Subscribe to the calculation status event. _ calculationTask.CalculationStatusChanged += new CalculationTask.CalculationStatusEventHandler( OnCalculationStatusChanged ); // Subscribe to the calculation progress event. _ calculationTask.CalculationProgressChanged += new CalculationTask.CalculationProgressEventHandler( OnCalculationProgressChanged );

Now that we have the .NET category XElement, we need to print out the name of the category rather than the entire XML fragment. As we can see, the name of the category is stored in the name attribute. As such, now seems like the perfect opportunity to introduce the Attribute axis method.

Now that we have the .NET category element in the form of an XElement, we want to query the XElement for the value of the name attribute. To retrieve the name attribute, we use the Attribute axis method. Like the Element axis method, Attribute returns the first matching attribute with the provided XName. In our case, we only have a single attribute defined on the XElement, but you can be sure that won t always be the case. Since we re interested in the name of the category, we ll call the Attribute axis method and pass name as a parameter, as shown in listing 10.3.

XElement root = XElement.Load("categorizedBooks.xml"); XElement dotNetCategory = root.Element("category"); XAttribute name = dotNetCategory.Attribute("name");

The event handlers for the calculation status and calculation progress events update the UI appropriately, for example by updating a status bar control.

Just like the Element axis method, Attribute returns the first attribute with the provided XName. If no attributes with the provided name are found, null is returned. Now that we have the name XAttribute in hand, we can output the title of the category to the console by casting the XAttribute to a string, as shown:

away. In other words, we don t want to see the result of this command, so we convert the result to void. Another way to do the same thing would be to pipe the result to Out-Null. Next, we re accessing the System.Reflection.Assembly type, which represents our application (which is PowerShell). I ve enclosed the type name in square brackets, as if I were declaring a variable to be of that type. But rather than declaring a variable, we re using two colons to access a static method of the type. Static methods exist without us having to create an instance of the type. The static method we re using is LoadWithPartialName(), which accepts the name of the framework component I want to load.

Console.WriteLine((string) name);

This results in the following output:
