C#一个方法返回多个值示例

static void main(string[] args)
        {
            //声明
            int value;
            string stroutvalue;

            //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
            }
        }
