Console.Readline()之后的C#console Console.WriteLine()？

Question

我希望控制台输出基本上具有表单的一般外观.

以下是我希望输出显示的方式:

First Name:  //using Console.ReadLine() right here while there is other text below
Last Name:
Badge Number:

然后

First Name: Joe
Last Name: //using Console.ReadLine() right here while there is other text below
Badge Number:

最后

First name: Joe
Last name: Blow
Badge Number:  //using Console.ReadLine() right here

你需要这个Console.SetCursorPosition()方法.

Console.WriteLine("First Name: ");
Console.WriteLine("Last Name: ");
Console.WriteLine("Badge Number: ");
Console.SetCursorPosition(12, 0);
string fname = Console.ReadLine();
Console.SetCursorPosition(11, 1);
string lname = Console.ReadLine();
Console.SetCursorPosition(14, 2);
string badge = Console.ReadLine();

看看您可以使用控制台执行的所有操作.

为了好玩,让我们更加可重用:

IList<string> PromptUser(params IEnumerable<string> prompts)
{
    var results = new List<string>();
    int i = 0; //manual int w/ foreach instead of for(int i;...) allows IEnumerable instead of array
    foreach (string prompt in prompts)
    {
        Console.WriteLine(prompt);
        i++;
    }

    //do this after writing prompts, in case the window scrolled
    int y = Console.CursorTop - i; 

    if (y < 0) throw new Exception("Too many prompts to fit on the screen.");

    i = 0;
    foreach (string prompt in prompts)
    {
        Console.SetCursorPosition(prompt.Length + 1, y + i);
        results.Add(Console.ReadLine());
        i++;
    }
    return results;
}

然后你会这样称呼它:

var inputs = PromptUser("First Name:", "Last Name:", "Badge Number:");
