我希望它显示像这个很棒的 Linux 命令这样的非闪烁动画;sl

我会很感激说......一只苍蝇的一个小而愚蠢的例子。

谢谢!

Console.SetCursorPosition用于将光标移动到某个位置,然后Console.Write是一个字符。在每一帧之前,您必须通过用空格覆盖它来删除前一帧。这是我刚刚构建的一个小例子:

class Program
{
    static void Main(string[] args)
    {
        char[] chars = new char[] { '.', '-', '+', '^', '°', '*' };
        for (int i = 0; ; i++)
        {
            if (i != 0)
            {
                // Delete the previous char by setting it to a space
                Console.SetCursorPosition(6 - (i-1) % 6 - 1, Console.CursorTop);
                Console.Write(" ");
            }

            // Write the new char
            Console.SetCursorPosition(6 - i % 6 - 1, Console.CursorTop);
            Console.Write(chars[i % 6]);

            System.Threading.Thread.Sleep(100);
        }
    }
}

例如,您可以获取一个动画 gif,从中提取所有单帧/图像(请参阅此处的操作方法),应用 ASCII 转换(例如,此处描述的操作方法)并像在上面的代码示例。

更新

只是为了好玩,我实现了我刚才描述的内容。只需尝试用@"C:\some_animated_gif.gif"一些(不是大的)动画 gif 的路径替换它。例如,从此处获取 AJAX 加载程序 gif 。

class Program
{
    static void Main(string[] args)
    {
        Image image = Image.FromFile(@"C:\some_animated_gif.gif");
        FrameDimension dimension = new FrameDimension(
                           image.FrameDimensionsList[0]);
        int frameCount = image.GetFrameCount(dimension);
        StringBuilder sb;

        // Remember cursor position
        int left = Console.WindowLeft, top = Console.WindowTop;

        char[] chars = { '#', '#', '@', '%', '=', '+', 
                         '*', ':', '-', '.', ' ' };
        for (int i = 0; ; i = (i + 1) % frameCount)
        {
            sb = new StringBuilder();
            image.SelectActiveFrame(dimension, i);

            for (int h = 0; h < image.Height; h++)
            {
                for (int w = 0; w < image.Width; w++)
                {
                    Color cl = ((Bitmap)image).GetPixel(w, h);
                    int gray = (cl.R + cl.G + cl.B) / 3;
                    int index = (gray * (chars.Length - 1)) / 255;

                    sb.Append(chars[index]);
                }
                sb.Append('\n');
            }

            Console.SetCursorPosition(left, top);
            Console.Write(sb.ToString());

            System.Threading.Thread.Sleep(100);
        }
    }
}
