Person-b was on the right track, but their code needs some changes:
Person-b 走在正确的轨道上，但他们的代码需要一些更改：
static void Main()
{
string txt = "Hello, world!";
while (true)
{
WriteBlinkingText(txt, 500, true);
WriteBlinkingText(txt, 500, false);
}
}
private static void WriteBlinkingText(string text, int delay, bool visible)
{
if (visible)
Console.Write(text);
else
for (int i = 0; i < text.Length; i++)
Console.Write(" ");
Console.CursorLeft -= text.Length;
System.Threading.Thread.Sleep(delay);
}
EDIT: Refactored the code a little
编辑：稍微重构代码

string txt = "Hello, world!";
while ( doingSomething )
{
Console.Write(txt);
System.Threading.Thread.Sleep(20);
Console.CursorLeft -= txt.Length;
for ( int i = 0; i < txt.Length; i++ )
Console.Write(" ");
}
this code does not make it blink though
这段代码并没有让它闪烁

There is no direct support, you will need to overwrite the text with spaces (or in different colours) based on a timer.
没有直接支持，您需要根据计时器用空格（或不同颜色）覆盖文本。

I improved Matthew's code a bit using \rand some fancy use of String:
我改进了 Matthew 的代码，\r并使用了一些奇特的用法String：
static void Main()
{
string txt = "Hello, world!";
WriteBlinkingText(txt, 500);
}
private static void WriteBlinkingText(string text, int delay)
{
bool visible = true;
while (true)
{
Console.Write("\r" + (visible ? text : new String(' ', text.Length)));
System.Threading.Thread.Sleep(delay);
visible = !visible;
}
}
I also think that the WriteBlinkingTextmethod should be self-contained, so the loop is inside here, but that's just a matter of personal taste I guess :)
我也认为该WriteBlinkingText方法应该是独立的，所以循环就在这里，但这只是我个人品味的问题:)

private void timer1_Tick(object sender, EventArgs e)//This might work better for you :)
{
Random rand = new Random();
for (int i = 0; i < 255; i++)
{
int A = rand.Next(i);
int R = rand.Next(i);
int G = rand.Next(i);
int B = rand.Next(i);
label2.ForeColor = Color.FromArgb(A, R, G, B);
}
}

To do this you will have to use:
为此，您必须使用：
console.clear
控制台清除
which will clear all the information in the console, but allow you to simulate a blinking text, by doing the following code you can do this: (This is in VB but its easily translated)
这将清除控制台中的所有信息，但允许您模拟闪烁的文本，通过执行以下代码，您可以执行此操作：（这是在 VB 中，但很容易翻译）
Dim Flash As Integer
Flash = 0
While Flash < 100 (Any number can be put here for duration)
Flash = Flash + 1
console.Backgroundcolor = consolecolor.Black
console.clear
system.threading.thread.sleep(25)
console.Backgroundcolor = consolecolor.White
console.clear
system.threading.thread.sleep(25)
End While
And that would give a blinking screen for example, for the blinking text simply adjust it:
例如，这将给出一个闪烁的屏幕，对于闪烁的文本，只需对其进行调整：
Dim FlashWord As Integer
FlashWord = 0
While FlashWord < 100 (Any number can be put here for duration)
FlashWord = FlashWord + 1
console.Foregroundcolor = consolecolor.Black
console.clear
Console.Writeline("Hello World")
system.threading.thread.sleep(25)
console.Foregroundcolor = consolecolor.White
console.clear
Console.Writeline("Hello World")
system.threading.thread.sleep(25)
End While
And this will simulate 'flashing', the only down side is that you lose your previous on-screen info, but nothing else, and for an effect this is pretty good!
这将模拟“闪烁”，唯一的缺点是您会丢失以前的屏幕信息，但没有其他内容，而且效果非常好！

Why not use backspace and rewrite the text on the same screen line?
为什么不使用退格键并在同一屏幕行上重写文本？
string blink = "Password Please!"
while (!System.Console.KeyAvailable)
{
Console.Write(blink);
Thread.Sleep(650);
for (int j = 1; j <= blink.Length + 2; j++)
{
Console.Write("\b"+(char)32+"\b");
if (j == blink.Length + 2) Thread.Sleep(650);
}
}
