任务：参数传递

using System;using System.Threading;using System.Threading.Tasks;namespace TaskExample{class c4{static void Main(){var t1 = new Task<Tuple<int, int> > ( Fun2,  Tuple.Create< int, int >( 16, 5 ) );t1.Start();Console.WriteLine( t1.Result );t1.Wait();Console.WriteLine( "result from task: {0} {1}", t1.Result.Item1, t1.Result.Item2 );string str = "Hello";var t2 = new Task<Tuple<int>>( Fun1, str );t2.Start();t2.Wait();Console.WriteLine( "result of t2 is {0}.", t2.Result.Item1 );}static Tuple< int, int > Fun2( object division ){Tuple< int, int > div = (Tuple<int, int > )division;int result = div.Item1 / div.Item2;int reminder = div.Item1 % div.Item2;Console.WriteLine( "task creates a result..." );return Tuple.Create< int, int >( result, reminder );}static Tuple<int> Fun1( object msg ){Console.WriteLine( msg );return Tuple.Create<int>(1);}}}

运行结果：

task creates a result...(3, 1)result from task: 3 1Helloresult of t2 is 1.

t1：传入2个参数，返回2个参数。

t2：传入1个参数，返回1个参数。返回值是一个时，也可以参考t1的方法。

不论是参数还是返回值，都可以是多个，具体都看Tuple。
