C# 10 does not support the ParameterizedThreadStart delegate An alternative method to pass data in C# 10 is to store it in a location accessible from both threads The problem is associating a thread with its own data It is sometimes necessary to define a class that contains the thread delegate, instantiate this new class, set the shared data, and call the thread to start the delegate associated with the new class method For many scenarios, this is overkill The THReadPool class, described next, is a simpler mechanism

return first < second; } }

Regardless of the number of processors, excess threads affect performance SystemThreadingThreadPool manages threads, including the reuse of expired threads, based on resources Accessing threads in ThreadPool is similar to explicit use of the THRead class However, as Listing 155 shows, THReadPool has the advantage of passing parameters even in the 10 implementation, where ParameterizedThreadStart is unavailable

In this example, an anonymous method is converted into a separately declared static method that is then instantiated as a delegate and passed as a parameter

Outer Variables Local variables declared outside a lambda expression (including parameters), but captured (accessed) within the lambda expression, are outer variables of that lambda this is also an outer variable Outer variables captured by anonymous functions live on until after the anonymous function s delegate is destroyed In Listing 1221, it is relatively trivial to use an outer variable to count how many times BubbleSort() performs a comparison Output 122 shows the results of this listing

using System; using SystemThreading; public class ThreadPools { public const int Repetitions = 1000; public static void Main() { ThreadPoolQueueUserWorkItem(DoWork, ''); for { } // Pause until the thread completes ThreadSleep(1000); } public static void DoWork(object state) { (int count = 0; count < Repetitions; count++) ConsoleWrite('-');

class DelegateSample { // static void Main(string[] args) { int i; int[] items = new int[5]; int comparisonCount=0; for (i=0; i<itemsLength; i++) { ConsoleWrite("Enter an integer:"); items[i] = intParse(ConsoleReadLine()); } BubbleSort(items, (int first, int second) => { comparisonCount++; return first < second;

for (int count = 0; count < Repetitions; count++) { ConsoleWrite(state); } } }

} ); for (i = 0; i < itemsLength; i++) { ConsoleWriteLine(items[i]); } ConsoleWriteLine("Items were compared {0} times", comparisonCount); } }

OUTPUT 122:

The results of Listing 155 appear in Output 154 Output 154 shows the same intermingling of and - as Output 153 does The thread pool class does not return a handle to the thread itself, which prevents the calling thread from controlling it with the thread management functions described earlier in the chapter, or easily monitoring its state to determine when it completes Assuming these deficiencies are not critical, developers should consider using the thread pool over explicit thread creation This provides more-efficient execution on single- and multiprocessor computers as well as a simple means for passing arbitrary data, even within the 10 framework

inside it After calling the BubbleSort() method, comparisonCount is printed out to the console As this code demonstrates, the C# compiler takes care of generating CIL code that shares comparisonCount between the anonymous method and the call site, even though there is no parameter to pass comparisonCount within the anonymous delegate, nor within the BubbleSort() method Given the sharing of the variable, it will not be garbage-collected until after the delegate that references it is garbage-collected In other words, the lifetime of the captured variable is at least as long as that of the longest-lived delegate object capturing it

ADVANCED TOPIC Outer Variable CIL Implementation The CIL code generated by the C# compiler for outer variables is more complex than the code for a simple anonymous method Listing 1222 shows the C# equivalent of the CIL code used to implement outer variables

Unfortunately, however, thread pool use is not without its pitfalls Activities like I/O operations and other framework methods that internally use the thread pool can consume threads as well Consuming all threads within the pool can delay execution and, in extreme cases, cause a deadlock
