.NET 4定义了8个Tuple类，和一个静态Tuple类

---------------------------------------------------------------------返回多个值

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;namespaceConsoleApplication2{classProgram{staticvoidMain(string[]args){Console.WriteLine("{0}*{1}={2}",Divide(1,2).Item1,Divide(1,2).Item2,Divide(1,2).Item3);//1*2=2Console.ReadKey();}publicstaticTuple<int,int,int>Divide(inti,intj)//{returnTuple.Create<int,int,int>(i,j,i*j);//返回三个值}}}
