From http://www.cnblogs.com/yunfeifei/p/4106318.html 使用token和轮询方式在task执行过程中return，也可throw exception

	var tokenSource = new CancellationTokenSource();
	var token = tokenSource.Token;
	var task = Task.Factory.StartNew(() =>
	{
	for (var i = 0; i < 1000; i++)
	{
	System.Threading.Thread.Sleep(1000);
	if (token.IsCancellationRequested)
	{
	Console.WriteLine("Abort mission success!");

From https://msdn.microsoft.com/en-us/library/hh191443.aspxawait 分开使用，返回值Task<>

	// Three things to note in the signature:
	// - The method has an async modifier.
	// - The return type is Task or Task<T>. (See "Return Types" section.)
	// Here, it is Task<int> because the return statement returns an integer.
	// - The method name ends in "Async."
	async Task<int> AccessTheWebAsync()
	{
	// You need to add a reference to System.Net.Http to declare client.
	HttpClient client = new HttpClient();
