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 1
Hello
result 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。
