C#实现跑马灯效果

namespace test { class Test6 { static void Main(string[] args) { string str = "welcome to xfht"; //获取字符串str的长度 int length = str.Length; //获取控制台窗口的宽度 int width=Console.WindowWidth; //在字符串前添加width-length个空格 for (int i = 1; i <= width - length; i++) { str = " " + str; } int index = 0; while (true) { Console.Clear();//清除控制台中显示的信息（清屏） //截取字符串 string temp = str.Substring(index); Console.Write(temp); index++; System.Threading.Thread.Sleep(100); if (index > width) { index = 0; } } } } }
