示例1: Main
//引入命名空间
using System;
using System.IO;
using System.Threading.Tasks;
public class Example
{
public static void Main()
{
Task<string[]>[] tasks = new Task<string[]>[2];
String docsDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
tasks[0] = Task<string[]>.Factory.StartNew( () => Directory.GetFiles(docsDirectory));
tasks[1] = Task<string[]>.Factory.StartNew( () => Directory.GetDirectories(docsDirectory));
Task.Factory.ContinueWhenAll(tasks, completedTasks => {
Console.WriteLine("{0} contains: ", docsDirectory);
Console.WriteLine(" {0} subdirectories", tasks[1].Result.Length);
Console.WriteLine(" {0} files", tasks[0].Result.Length);
} );
}
}输出：
C:\Users\\Documents contains: 24 subdirectories 16 files
示例2: CancellationTokenSource
//引入命名空间
using System;
using System.Collections.Generic;
using System.Threading;
using System.Threading.Tasks;
public class Example
{
static CancellationTokenSource cts = new CancellationTokenSource();
static TaskFactory<int> factory = new TaskFactory<int>(
cts.Token,
TaskCreationOptions.PreferFairness,
TaskContinuationOptions.ExecuteSynchronously,
new CustomScheduler());
static void Main()
{
var t2 = factory.StartNew(() => DoWork());
cts.Dispose();
}
static int DoWork()
{
/*...*/
return DateTime.Now.Hour <= 12 ? 1 : 2;
}
}
