C# string.Join的用法

string.Join 可以将一个数组遍历连接起来通过阻断符连接成一个字符串

           var numbers = new string[] { "第一个", "第二个", "第三个","第四个","第五个","第六个" };

            var a = string.Join("/", numbers);

            //string.Join(阻隔符号, 数组, 起始数, 总数);
            var b = string.Join("/", numbers, 1, 1);
            var c = string.Join("/", numbers, 0, 1);
            var d = string.Join("-", numbers, 1, 3);
            var e =  string.Join("，", numbers, 1, 2);
            var f = string.Join("/", numbers, 0, 0);

            Console.WriteLine(a);
            Console.WriteLine(b);
            Console.WriteLine(c);
            Console.WriteLine(d);
            Console.WriteLine(e);
            Console.WriteLine(f);

结果：
