使用c#在终端中对齐字符串

Question

我正在寻求一点帮助。我是 C# 新手，正在尝试为我的孩子构建一个简单的加法/减法游戏来练习他的技能。到目前为止，我已经掌握了基础知识（还有更多需要开发），但有一个问题我正在寻求解决。

我如何在代码中设置字符串，它将在单独的行上打印几个随机数。我想将这些数字向右对齐，但并不总是有固定的位数。这是到目前为止的代码（可能很草率，所以我很抱歉）。

/* Basic build
- There are two numbers up to 6 numbers
- Number 1 must be higher than number 2 (-'s are still out of scope)
- Operation is randomized
- 10 Questions per round
- There will need to be a scoring system
*/

int num1;
int num2;
int answer;
string opperation = "+";
string guess;
int finalAnswer;
Random randNumber = new Random();
int score = 0;



for (int i = 0; i < 10; i++)
{
    num1 = randNumber.Next(0, 101);
    num2 = randNumber.Next(0, 101);
    string num1String = num1.ToString();
    string num2String = num2.ToString();

    answer = num1 + num2;
    Console.WriteLine($"  {num1String}\n+ {num2String}\n---------");
    guess = Console.ReadLine();

    while (!int.TryParse(guess, out finalAnswer))
    {
        Console.WriteLine("That is not a valid number. Please guess again:");
        guess = Console.ReadLine();
    }
    if (finalAnswer == answer)
    {
        score++;
        Console.WriteLine("That is correct! :)\n\n");
    }
    else
    {
        Console.WriteLine("That is Incorrect. :(\n\n");
    }
}

Console.WriteLine($"Your score is {score} out of 10");

---

当前输出的示例可能是

  100
+ 5
_________

我希望让它更像

      100
+       5
_________

我一直在研究，但找不到解决方案。

Answer 1

做例如

Console.WriteLine("  {0,8}\n+ {1,8}\n----------", num1, num2);

应该有帮助。
