尝试将字符串转换为数组,但字符串C#中没有任何空格

好的,所以我只是想出了一种如何将8位二进制代码转换为数字的方法(或者我认为),然后通过编写适合您的程序,有什么更好的学习方法!而且我有点被卡住了。我试图找出如何将字符串转换为字符串array [],这样我就可以遍历它并将所有内容加在一起,但是我似乎找不到不需要空格或任何内容的东西。任何人有任何想法吗?这是我的代码。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace binary_to_number
{
    class Program
    {
        static int GetAddition(int place)
        {
            switch(place) // goes through the switch until if finds witch place the binary is in 
            {
                case 1:
                    return 128;
                case 2:
                    return 64;
                case 3: return 32;
                case 4: return 16;
                case 5: return 8;
                case 6: return 4;
                case 7: return 2;
                case 8: return 1;
                default: return 0;


            }

        }

        static int ToInt(string input)
        {
            string[] binary = input.Split(); // right here is where im stuck 
            int thenumber = 0; // this is the number it adds to
            for(int i = 0;i < 9;i++)
            {
                Console.WriteLine(binary[i]);
            }
            return thenumber;
        }


        static void Main(string[] args)
        {

            while (true)
            {
                Console.WriteLine("Please put in a 8-digit binary");
                string input = Console.ReadLine();
                if (input.Length < 9) // binary has 8 digits plus the null at the end of each string so if its 
                { // not binary

                    Console.WriteLine(ToInt(input)); // function converts the input into binary
                }

            }



        }


    }
}

希望这会对您有所帮助。 String实现IEnumerable接口,该接口将为您提供用于枚举的枚举器。

        Console.WriteLine("Please enter 8 digit binary number");
        string input = Console.ReadLine();
        foreach (var item in input)
        {
            Console.WriteLine("Item is {0}", item);
        }

要开始修复程序,请执行以下操作:

string[] binary = input.Split(); // right here is where im stuck

应该是

char[] binary = input.ToCharArray();

另外for (int i = 0; i < 9; i++)应该是for (int i = 0; i < 8; i++)或更好的for (int i = 0; i < binary.Length; i++)


更好的方法吗?

通过使用Convert类,您可以节省大量代码。

while (true)
{
    Console.WriteLine("Please put a value as binary");
    string input = Console.ReadLine();
    var number = Convert.ToUInt16(input, 2);

    Console.WriteLine($"input:{input}, value: {number}, as binary: {Convert.ToString(number, 2)}");
}
/*
Please put a value as binary
1
input:1, value: 1, as binary: 1

Please put a value as binary
11
input:11, value: 3, as binary: 11

Please put a value as binary
10000001
input:10000001, value: 129, as binary: 10000001
