Variables that programmers declare outside an anonymous method and access within the implementation are outer variables They are available only when using anonymous methods where they are captured such that the C# compiler takes care of passing them, along with the delegate, and returning them at the end of the invocation In Listing 1314, it is relatively trivial to use an outer variable to count how many times swap is called by BubbleSort() Output 132 shows the results of this listing

handles, resources that require an explicit activity that the garbage collector doesn t know about Note that finalizers will execute on their own thread, making their execution even less determinant This indeterminacy makes an unhandled exception within a finalizer (outside of the debugger) difficult to diagnose because the circumstances that led to the exception are not clear From the user s perspective, the unhandled exception will be thrown relatively randomly and with little regard for any action the user was performing For this reason, take care to avoid exceptions within finalizers Use defensive programming techniques such as checking for nulls (refer to Listing 920)

Deterministic Finalization with the using Statement The problem with finalizers on their own is that they don t support deterministic finalization (the ability to know when a finalizer will run) Rather, finalizers serve the important role of a backup mechanism for cleaning up resources if a developer using a class neglects to call the requisite cleanup code explicitly For example, consider the TemporaryFileStream that not only includes a finalizer but also a Close() method The class uses a file resource that could potentially consume a significant amount of disk space The developer using TemporaryFileStream can explicitly call Close() in order to restore the disk space Providing a method for deterministic finalization is important because it eliminates a dependency on the indeterminate timing behavior of the finalizer Even if the developer fails to call Close() explicitly, the finalizer will take care of the call The finalizer will run later than if it was called explicitly, but it will be called Because of the importance of deterministic finalization, the Base Class Library includes a specific interface for the pattern and C# integrates the pattern into the language The IDisposable interface defines the details of the pattern with a single method called Dispose(), which developers call on a resource class to dispose of the consumed resources Listing 921 demonstrates the IDisposable interface and some code for calling it

class DelegateSample { // static void Main(string[] args) { int i; int[] items = new int[5]; int swapCount=0; for(i=0;i<itemsLength; i++) { ConsoleWrite("Enter an integer:"); items[i] = intParse(ConsoleReadLine()); } BubbleSort(items, delegate(int first, int second) { bool swap = first < second; if(swap) { swapCount++; } return swap; } ); for (i = 0; i < itemsLength; i++) { ConsoleWriteLine(items[i]); } ConsoleWriteLine("Items were swapped {0} times", swapCount); } }

using System; using SystemIO class TemporaryFileStream : IDisposable { public TemporaryFileStream() { _File = new FileInfo(PathGetTempFileName()); _Stream = new FileStream( FileFullName, FileModeOpenOrCreate, FileAccessReadWrite); } ~TemporaryFileStream() { Close(); } public FileStream Stream { get { return _Stream; } } readonly private FileStream _Stream; public FileInfo File { get { return _File; } } readonly private FileInfo _File; public void Close() { if(Stream != null) { StreamClose(); } if(File != null) { FileDelete(); } // Turn off calling the finalizer SystemGCSuppressFinalize(this); } #region IDisposable Members public void Dispose() { Close(); } #endregion }

class Program { // static void Search() { TemporaryFileStream fileStream = new TemporaryFileStream(); // Use temporary file stream; // fileStreamDispose(); // } }

The steps for both implementing and calling the IDisposable interface are relatively simple However, there are a couple of points you should not forget First, there is a chance that an exception will occur between the time TemporaryFileStream is instantiated and Dispose() is called If this happens, Dispose() will not be invoked and the resource cleanup will have to rely on the finalizer To avoid this, callers need to implement a try/finally block Instead of coding such a block explicitly, C# provides a using statement expressly for the purpose The resultant code appears in Listing 922

swapCount appears outside the anonymous method and is incremented inside it After calling the BubbleSort() method, swapCount is printed out to the console

class Program { // static void Search() { using (TemporaryFileStream fileStream1 = new TemporaryFileStream(), fileStream2 = new TemporaryFileStream()) { // Use temporary file stream; } } }
