C#初级语法(3)

1.结构体

        enum Direction
        {
            West,
            North,
            East,
            South
        }
        struct Path
        {
            public float distance;
            public Direction dir;
        }
        static void Main(string[] args)
        {
            Path path1;
            path1.dir = Direction.South;
            path1.distance = 1000;
        }

2.foreach遍历数组

            int[] scores = { 1, 2, 3, 34, 4, 5, 6, 7 };
            foreach (int temp in scores)
            {
                Console.WriteLine(temp);

            }
            Console.ReadKey();

3.字符串的处理

            string str = "WWW.BAIDU.COM";
            string res = str.ToLower();
            Console.WriteLine(res);
            Console.ReadKey();

ToLower()将字符串转换成小写,ToUpper()讲字符串转换成大写

Trim()去掉字符串前后的空格,

Split() 返回一个字符数组,将参数作为分割符,将一段字符串分割成几个字符串
