Answer 1

使用Console.SetCursorPosition将光标设置在最后一行的开头并重写它。

类似于:

Console.WriteLine(dir);
Console.SetCursorPosition(0, Console.CursorTop - 1);

编辑:

根据您的评论，您可以执行以下操作:

Console.WriteLine("Searching file in...");
foreach (var dir in DirList)
{
    ClearCurrentConsoleLine();
    Console.Write(dir);
}

ClearCurrentConsoleLine 定义为:

public static void ClearCurrentConsoleLine()
{
    int currentLineCursor = Console.CursorTop;
    Console.SetCursorPosition(0, Console.CursorTop);
    for (int i = 0; i < Console.WindowWidth; i++)
        Console.Write(" ");
    Console.SetCursorPosition(0, currentLineCursor);
}
