我的输入在途中某处丢失(打印0) [英] My input gets lost somewhere along the way(printing 0s)

问题描述

尝试对包含以下内容的数据列表进行排序:

Trying to sort a list of data that contains the following:

txt.文件目前看起来像这样，但将扩展为包含更多(大约100个左右). 900只是一个上限.

The txt. file currently looks like this but will be extended to include more, about 100 or so. 900 is just used as an upper limit.

21，f，s，14

21,f, s, 14

41，f，m，22

41,f, m, 22

12，m，s，12

12, m, s, 12

11，f，s，8

29，m，m，4

6，m，s，12

9，f，s，2

30，f，s，1

             ages[idx] = districtDataA[idx];
         }
     }


    //This module displays the data
     static void DisplayData(int[] countDistrict, int[] districtDataA, int[] ages)

        int index = 0;
        for (index = 0; index < countDistrict.Length; index++)
        {
            Console.WriteLine(" District {0}: {1}", index + 1, countDistrict[index]);
        }

        int x = 0;
        for (x = 0; x < ages.Length; x++)
        {
            Console.WriteLine("Ages over {0} : {1}", ages[x], districtDataA[x]);
        }
    }
}

当前输出如下:

我的数据在哪里丢失?

推荐答案

您的ReadFile错误.尝试这样的事情.

Your ReadFile is wrong. Try something like this instead.

static void ReadFile(int[] districtDataD, string[] districtDataG, string[] districtDataM, int[] districtDataA)
{
   // Read in the file contents
    string[] lines = File.ReadAllLines("census.txt");
    int i =0;
    //iterate through each line
    foreach(var line in lines)
    {
      //split the line by a comma
      string[] parts = line.Split(',');

            districtDataD[i] = int.Parse(parts[0]);
            districtDataG[i] = parts[1];
            districtDataM[i] = parts[2];
            districtDataA[i] = int.Parse(parts[3]);
            i++;
    }

}

您当前正在读取文件，并将其分配给lines，然后再次读取文件，并将值分配给line.如果使用foreach，则可以轻松地遍历每一行，而不必跟踪您所在的行.

You are currently reading in the file and assigning it to lines then reading the file in again and assigning the value to line. If you use foreach you can easily loop through each line without having to keep track of which line you are on.
