示例1: Main
//引入命名空間
using System;
using System.Threading;
using System.Threading.Tasks;
class ThreadLocalDemo
{
// Demonstrates:
// ThreadLocal(T) constructor
// ThreadLocal(T).Value
// One usage of ThreadLocal(T)
static void Main()
{
// Thread-Local variable that yields a name for a thread
ThreadLocal<string> ThreadName = new ThreadLocal<string>(() =>
{
return "Thread" + Thread.CurrentThread.ManagedThreadId;
});
// Action that prints out ThreadName for the current thread
Action action = () =>
{
// If ThreadName.IsValueCreated is true, it means that we are not the
// first action to run on this thread.
bool repeat = ThreadName.IsValueCreated;
Console.WriteLine("ThreadName = {0} {1}", ThreadName.Value, repeat ? "(repeat)" : "");
};
// Launch eight of them. On 4 cores or less, you should see some repeat ThreadNames
Parallel.Invoke(action, action, action, action, action, action, action, action);
// Dispose when you are done
ThreadName.Dispose();
}
}
// This multithreading example can produce different outputs for each 'action' invocation and will vary with each run.
// Therefore, the example output will resemble but may not exactly match the following output (from a 4 core processor):
// ThreadName = Thread5
// ThreadName = Thread6
// ThreadName = Thread4
// ThreadName = Thread6 (repeat)
// ThreadName = Thread1
// ThreadName = Thread4 (repeat)
// ThreadName = Thread7
// ThreadName = Thread5 (repeat)
