Silky 的评论是正确的答案:

Silky's comment is the right answer:

• 设置合适的背景颜色
• 为您希望清除的每一行循环:
  • 将光标位置设置在左侧
  • 写出一串合适宽度的空格

  例如:

  public static void ClearArea(int top, int left, int height, int width) 
  {
      ConsoleColor colorBefore = Console.BackgroundColor;
      try
      {
          Console.BackgroundColor = ConsoleColor.Black;
          string spaces = new string(' ', width);
          for (int i = 0; i < height; i++)
          {
              Console.SetCursorPosition(left, top + i);
              Console.Write(spaces);
          }
      }
      finally
      {
          Console.BackgroundColor = colorBefore;
      }
  }
  

  请注意，这将恢复背景颜色，但不会恢复之前的光标位置.

  Note that this will restore the background colour, but not the previous cursor location.
