c#的params参数使用示例

class 参数
    {
        public void dosome(string str,params int[] values){
            if (values != null && values.length > 0)
            {
                for (var i = 0; i < values.length; i++)
                {
                    console.writeline(str + "," + values[i]);
                }
            }
            else {
                console.writeline(str);
            }
        }
        static void main() {
            参数 c = new 参数();
            c.dosome("a");
            c.dosome("b",1);
            c.dosome("c",1,2,3);
            int[] arr = { 1, 5, 7 };
            c.dosome("d",arr);
        }
    }
