C＃控制台 – 将光标位置设置为最后一个可见行

我想将控制台中光标的位置设置为最后一条可见线。 我怎样才能做到这一点？

Answer 1

如果您指的是窗口的最后一行，则可以使用Console.CursorTop和Console.WindowHeight以及Console.WindowTop 。 示例代码：

 using System; class Test { static void Main() { Console.Write("Hello"); WriteOnBottomLine("Bottom!"); Console.WriteLine(" there"); } static void WriteOnBottomLine(string text) { int x = Console.CursorLeft; int y = Console.CursorTop; Console.CursorTop = Console.WindowTop + Console.WindowHeight - 1; Console.Write(text); // Restore previous position Console.SetCursorPosition(x, y); } } 

请注意，这必须考虑Console.WindowTop以找出您在缓冲区中的位置…

我也必须解决这个问题，并提出这个问题：

 public class Program { static int id = 0 , idOld = 0, idSelected = -1; static string[] samples; public static void Main() { Console.BackgroundColor = ConsoleColor.DarkBlue; Console.ForegroundColor = ConsoleColor.Yellow; Console.WindowWidth = 90; Console.WindowHeight = 36; Console.WindowTop = 5; Console.Title = "My Samples Application"; Console.InputEncoding = Encoding.GetEncoding("windows-1251"); samples = new string[50]; for (int i = 0; i < samples.Length; i++) samples[i] = "Sample" + i; LoopSamples(); } static void SelectRow(int y, bool select) { Console.CursorTop = y + 1; Console.ForegroundColor = select ? ConsoleColor.Red : ConsoleColor.Yellow; Console.WriteLine("\t{0}", samples[y]); Console.CursorTop = y; } static void LoopSamples() { int last = samples.Length - 1; ShowSamples(); SelectRow(0, true); while (true) { while (idSelected == -1) { idOld = id; ConsoleKey key = Console.ReadKey(true).Key; switch (key) { case ConsoleKey.UpArrow: case ConsoleKey.LeftArrow: if (--id < 0) id = last; break; case ConsoleKey.DownArrow: case ConsoleKey.RightArrow: if (++id > last) id = 0; break; case ConsoleKey.Enter: idSelected = id; return; case ConsoleKey.Escape: return; } SelectRow(idOld, false); SelectRow(id, true); } } } static void ShowSamples() { Console.Clear(); Console.ForegroundColor = ConsoleColor.Yellow; Console.WriteLine("Use arrow keys to select a sample. Then press 'Enter'. Esc - to Quit"); for (int i = 0; i < samples.Length; i++) Console.WriteLine("\t{0}", samples[i]); } }
