Math.Round 四舍六入五取偶

            double result1 = Math.Round(0.3);
            Console.WriteLine(result1);//result1显示0

            double result2 = Math.Round(1.5);
            Console.WriteLine(result2);//result2显示2

　　　　　　　double result = Math.Round(0.5);
            Console.WriteLine(result);//result显示0

            double result3 = Math.Round(0.6);
            Console.WriteLine(result3);//result1显示1         

            Console.Read();
