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
