Question

我需要将用户输入的数字（最多五位数）与中间的三个空格分开。因此，如果用户输入数字12345，则控制台打印出来，＆＃34; 1 2 3 4 5＆＃34;。

我只是让控制台打印出数字：

database.yml

Answer 1

static void Main()
{
    Console.Write("Please enter in a five digit number: ");
    Console.WriteLine(string.Join(" ", Console.ReadLine().ToCharArray()));
    Console.Read();
}

Answer 2

Hımmm，看起来像是一个家庭作业;）

Console.WriteLine("Please enter in a five digit number: ");
string userInput = Console.ReadLine();

for (int i = 0; i < userInput.Length; i++) {
 char[] ip = userInput.ToCharArray();
 Console.Write(ip[i] + "   ");
}
Console.ReadKey();

或

Console.WriteLine("Please enter in a five digit number: ");
string userInput = Console.ReadLine();

foreach(char c in userInput) {
 Console.Write(c + "   ");
}
Console.Read();

Answer 3

        Console.WriteLine("Please enter in a five digit number: ");
        string num = Console.ReadLine();
        string result = "";
        foreach (char n in num)
        {
            result += n + "   ";
        }
        Console.Write(result);
        Console.ReadKey();

Answer 4

这应该可以帮到你：）

class MainClass
{
    Console.WriteLine ("Please enter in a five digit number: ")
    string answer = string.Empty;
    int userInput = 0;

    for(int i = 0, i < 5, i++)
    {
        userInput = Console.ReadLine();

        // Append 3 spaces to each input provided by the user
        answer = string.Format("{0}{1}{3}",answer, userInput, "   ");
    }

    Console.WriteLine(answer)
}

用空格分隔用户输入数字
