让用户按特定键以继续程序

我目前正在开发一个小型彩票控制台游戏，并想添加一个“工作”机制。我创建了一个新方法，想要添加多个任务，您必须按特定键，例如空格键 > 例如多次。所以像这样（但实际上有效）：

static void Work()
{
  Console.WriteLine("Task 1 - Send analysis to boss");
  Console.WriteLine("Press the spacebar 3 times");
  Console.ReadKey(spacebar);
  Console.ReadKey(spacebar);
  Console.ReadKey(spacebar);
  Console.WriteLine("Task finished - Good job!");
  Console.ReadKey();
}

I am currently working on a little lottery console game and wanted to add a "Working" mechanic. I created a new method and want to add multiple tasks where you have to press a specific key like the space bar for example multiple times. So something like this (but actually working):

static void Work()
{
  Console.WriteLine("Task 1 - Send analysis to boss");
  Console.WriteLine("Press the spacebar 3 times");
  Console.ReadKey(spacebar);
  Console.ReadKey(spacebar);
  Console.ReadKey(spacebar);
  Console.WriteLine("Task finished - Good job!");
  Console.ReadKey();
}

Console.ReadKey() 方法返回一个 ConsoleKeyInfo 结构，该结构为您提供有关按下哪个键和修饰符所需的所有信息。您可以使用此数据来过滤输入：

void WaitForKey(ConsoleKey key, ConsoleModifiers modifiers = default)
{
    while (true)
    {
        // Get a keypress, do not echo to console
        var keyInfo = Console.ReadKey(true);
        if (keyInfo.Key == key && keyInfo.Modifiers == modifiers)
            return;
    }
}

在您的用例中，您可以这样调用：

WaitForKey(ConsoleKey.SpaceBar);

或者您可以添加专门检查 ConsoleKey.SpaceBar 的 WaitForSpace 方法没有修饰符。

对于更复杂的键盘交互（例如菜单和一般输入处理），您需要功能更强大的东西，但基本概念是相同的：使用Console.ReadKey(true)来获取输入（不显示按下的键），检查结果 ConsoleKeyInfo 记录以确定按下了什么，等等。但是对于等待按下特定键的简单情况，这将起到作用。

The Console.ReadKey() method returns a ConsoleKeyInfo structure which gives you all the information you need on which key and modifiers were pressed. You can use this data to filter the input:

void WaitForKey(ConsoleKey key, ConsoleModifiers modifiers = default)
{
    while (true)
    {
        // Get a keypress, do not echo to console
        var keyInfo = Console.ReadKey(true);
        if (keyInfo.Key == key && keyInfo.Modifiers == modifiers)
            return;
    }
}

In your use case you'd call that like this:

WaitForKey(ConsoleKey.SpaceBar);

Or you could add a WaitForSpace method that specifically checks for ConsoleKey.SpaceBar with no modifiers.

For more complex keyboard interactions like menus and general input processing you'll want something a bit more capable, but the basic concept is the same: use Console.ReadKey(true) to get input (without displaying the pressed key), check the resultant ConsoleKeyInfo record to determine what was pressed, etc. But for the simple case of waiting for a specific key to be pressed that will do the trick.
