C#一个方法返回多个值示例

            //调用函数
            //函数的参数有两个返回的值
            ReturnMulValue(out strOutValue,out value);

            Console.WriteLine("Call ReturnMulValue(out string strOut, out int i)");
            Console.WriteLine("value = {0:N}", value);//value = 1.00
            Console.WriteLine("Out string value = " + strOutValue); //Out string value = out function

            //调用函数 http://www.cnblogs.com/roucheng/
            //函数原返回值与参数中均得到返回的值
            value = ReturnMulValue(out strOutValue);

            Console.WriteLine("Call ReturnMulValue(out string strOut)");
            Console.WriteLine("value = {0:N}", value);//value = 2.00
            Console.WriteLine("Out string value = " + strOutValue);//Out string value = out function 2

            //声明
            int[] outArr;
            //调用函数
            //函数返回数组
            ReturnMulArr(out outArr, out value);

            Console.WriteLine("Call ReturnMulArr(out int[] arr, out int i)");
            Console.WriteLine("value = {0:N}", value);//value = 3.00
            Console.WriteLine("Out arr value ");

            for (int j = 0; j < outArr.Length; j++)
            {
                Console.Write(outArr[j]);//12345
            }
        }
