C#一个方法返回多个值建议收藏

 1 static void Main(string[] args)
 2         {
 3             //声明
 4             int value;
 5             string strOutValue;
 6 
 7             //调用函数
 8             //函数的参数有两个返回的值
 9             ReturnMulValue(out strOutValue,out value);
10 
11             Console.WriteLine("Call ReturnMulValue(out string strOut, out int i)");
12             Console.WriteLine("value = {0:N}", value);//value = 1.00
13             Console.WriteLine("Out string value = " + strOutValue); //Out string value = out function
14 
15 
16             //调用函数 http://www.cnblogs.com/roucheng/
17             //函数原返回值与参数中均得到返回的值
18             value = ReturnMulValue(out strOutValue);

20             Console.WriteLine("Call ReturnMulValue(out string strOut)");

22             Console.WriteLine("Out string value = " + strOutValue);//Out string value = out function 2
