我想要达到这样的目标:
Time consuming operation...OK
Another time consuming operation...
And another one, but it completed, so...OK
我显示了3行文字,每行都与一个可以迟早结束的帖子相关。但如果第二个完成的时间晚于第三个,我会得到类似的结果:
Time consuming operation...OK
Another time consuming operation...
And another one, but it completed, so...OKOK
这当然是不可接受的。我知道如何回到当前的路线,但有没有办法上线?我发誓我已经在某个地方见过它,虽然它可能是一个Linux控制台:)
算了。见远程文件管理器!它适用于Windows控制台,甚至可以在PowerShell中运行!怎么做这样的东西?最酷的部分是退出后恢复控制台状态。所以也许我应该问 - 如何直接访问控制台缓冲区?我假设我需要一些原生代码才能完成这个伎俩,但也许还有另外一种方法呢?我想到每次更新清除控制台,但这似乎有点矫枉过正。或许它不是吗?它会眨眼吗?

您可以将光标移动到任意位置:Console.SetCursorPosition或使用Console.CursorTop。
Console.SetCursorPosition(0, Console.CursorTop -1);
Console.WriteLine("Over previous line!!!");

使用回车。此示例打印一行,覆盖之前的内容。
Console.WriteLine();
for (int i = 0; i <= 100; i++)
{
System.Threading.Thread.Sleep(10);
Console.Write("\x000DProgress: " + i);
}
只要您的所有字符串都少于80列(或者您的终端缓冲区设置为),此方法就可以正常工作。

注意:以下答案最初由OP编辑到问题中。
以下是演示的完整解决方案:
using System;
using System.Collections.Generic;
using System.Threading;
namespace PowerConsole {
internal class Containers {
internal struct Container {
public int Id;
public int X;
public int Y;
public string Content;
}
public static List<Container> Items = new List<Container>();
private static int Identity = 0;
public static int Add(string text) {
var c = new Container();
c.Id = Identity++;
c.X = Console.CursorLeft;
c.Y = Console.CursorTop;
c.Content = text;
Console.Write(text);
Items.Add(c);
return c.Id;
}
public static void Remove(int id) {
Items.RemoveAt(id);
}
public static void Replace(int id, string text) {
int x = Console.CursorLeft, y = Console.CursorTop;
Container c = Items[id];
Console.MoveBufferArea(
c.X + c.Content.Length, c.Y,
Console.BufferWidth - c.X - text.Length, 1,
c.X + text.Length, c.Y
);
Console.CursorLeft = c.X;
Console.CursorTop = c.Y;
Console.Write(text);
c.Content = text;
Console.CursorLeft = x;
Console.CursorTop = y;
}
public static void Clear() {
Items.Clear();
Identity = 0;
}
}
internal class Program {
private static List<Thread> Threads = new List<Thread>();
private static void Main(string[] args) {
Console.WriteLine("So we have some threads:\r\n");
int i, id;
Random r = new Random();
for (i = 0; i < 10; i++) {
Console.Write("Starting thread " + i + "...[");
id = Containers.Add("?");
Console.WriteLine("]");
Thread t = new Thread((object data) => {
Thread.Sleep(r.Next(5000) + 100);
Console.ForegroundColor = ConsoleColor.Green;
Containers.Replace((int)data, "DONE");
Console.ResetColor();
});
Threads.Add(t);
}
Console.WriteLine("\n\"But will it blend?\"...");
Console.ReadKey(true);
i = 0;
Threads.ForEach(t => t.Start(i++));
Threads.ForEach(t => t.Join());
Console.WriteLine("\r\nVoila.");
Console.ReadKey(true);
}
}
}
