// Simple threading scenario: Start a static method running
// on a second thread.
public class ThreadExample {
// The ThreadProc method is called when the thread starts.
// It loops ten times, writing to the console and yielding
// the rest of its time slice each time, and then ends.
public static void ThreadProc() {
for (int i = 0; i < 10; i++) {
Console.WriteLine("ThreadProc: {0}", i);
// Yield the rest of the time slice.
Thread.Sleep(0);
}
}
public static void Main() {
Console.WriteLine("Main thread: Start a second thread.");
// The constructor for the Thread class requires a ThreadStart
// delegate that represents the method to be executed on the
// thread. C# simplifies the creation of this delegate.
Thread t = new Thread(new ThreadStart(ThreadProc));
// Start ThreadProc. On a uniprocessor, the thread does not get
// any processor time until the main thread yields. Uncomment
// the Thread.Sleep that follows t.Start() to see the difference.
t.Start();
//Thread.Sleep(0);
for (int i = 0; i < 4; i++) {
Console.WriteLine("Main thread: Do some work.");
Thread.Sleep(0);
}
Console.WriteLine("Main thread: Call Join(), to wait until ThreadProc ends.");
t.Join();
Console.WriteLine("Main thread: ThreadProc.Join has returned. Press Enter to end program.");
Console.ReadLine();
}
}
此代码产生的输出类似如下内容:
Main thread: Start a second thread.
Main thread: Do some work.
ThreadProc: 0
Main thread: Do some work.
ThreadProc: 1
Main thread: Do some work.
ThreadProc: 2
Main thread: Do some work.
ThreadProc: 3
Main thread: Call Join(), to wait until ThreadProc ends.
ThreadProc: 4
ThreadProc: 5
ThreadProc: 6
ThreadProc: 7
ThreadProc: 8
ThreadProc: 9
Main thread: ThreadProc.Join has returned. Press Enter to end program.
