访问字符串数组中的字符

Question

我有一个字符串数组,如下所示.我正在迭代字符串数组并打印每个字符串元素的第四个字符,它始终为1.

我一直在尝试做的是实现一个if语句,这样如果每个元素的每个第四个字符为1然后打印一些东西,但我不确定如何访问我正在迭代的每个元素.

我添加了一个带有一些伪代码的if语句来尝试突出我想要做的事情.谢谢你的帮助.

       namespace ConsoleApplication6
       {
          class Program
              {
           static void Main()
              {
        string[] bitstrings = new string[16];
        bitstrings[0] = "00101";
        bitstrings[1] = "00001";
        bitstrings[2] = "00001";
        bitstrings[3] = "00101";
        bitstrings[4] = "00101";
        bitstrings[5] = "00101";
        bitstrings[6] = "00101";
        bitstrings[7] = "00101";
        bitstrings[8] = "00101";
        bitstrings[9] = "00101";
        bitstrings[10] = "00101";
        bitstrings[11] = "00101";
        bitstrings[12] = "00101";
        bitstrings[13] = "00101";
        bitstrings[14] = "00101";
        bitstrings[15] = "00101";

        for (int x = 0; x < bitstrings.Length; x++)
        {

            int s = bitstrings[x][4];
            Console.ReadLine();



        }

        if(/*all bitstrings[x][4] = 1*/)
        {
            //print something
        }

    }
}
 }

你的代码就在那里,你只需要记住字符串中的每个字符,无论其值如何,仍然是一个字符.你的if语句也需要在for循环中.

for (int x = 0; x < bitstrings.Length; x++)
{
    //3 instead of 4 because arrays are 0 indexed
    if(bitstrings[x][3] == '1')
    {
       //valid char
    }
}
//Also don't need to read like every iteration.
Console.ReadLine(); 

编辑:如果所有第4个元素必须为1,则将其修改为包含布尔值,如果找到无效的char,则将其分解

bool allOne = true;
for (int x = 0; x < bitstrings.Length; x++)
{
    //3 instead of 4 because arrays are 0 indexed
    if(bitstrings[x][3] != '1')
    {
       allOne = false;
       break;
    }
}
if(allOne)
{ 
   //Do something
}

Console.ReadLine();
