多维数组中的列

本文关键字：数组 | 更新日期: 2023-09-27 18:16:54

我在文本中有这样的数据:

跳蚤,0,0,1,0,0,0,0,0,0,1,0,0,0,0,0,6

青蛙,0,0,1,0,0,1,1,1,1,- 1,0,0,4,0,0,0,5

青蛙,0,0,1,0,0,1,1,1,1,1,- 1,0,4,0,0,0,5

我需要计算所选列中0的个数，例如在第一列中有3个0。

下面是我的代码: 
        //data patch
        string[] tekst = File.ReadAllLines(@"C:'zoo.txt");

        //full of array 
        string[] tablica = tekst;

        for(int s=0;s<tablica.Length;s++)
        {
            Console.WriteLine(tablica[s]);
        }
        //----------------Show all of array---------------------------//

        //----------------Giv a number of column-----------------////
        Console.WriteLine("Podaj kolumne");
        int a = Convert.ToInt32(Console.ReadLine());
        //Console.WriteLine("Podaj wiersz");
        //int b = Convert.ToInt32(Console.ReadLine());
        int n = tablica.Length;
        int m = tablica[a].Split(',').Length;
       string[,] liczby = new string[n, m];
        for (int j = 0; j < n; j++)
        {
            int suma = 0;
            for (int i = 0; i < m; i++)
            {
               //somethink should be here
            }
        }

有解决这个问题的办法吗?

多维数组中的列

try:

//data patch
string[] tekst = File.ReadAllLines(@"C:'zoo.txt");

//full of array - you allready have a string[], no need for a new one
//string[] tablica = tekst;

for(int s=0;s<tekst.Length;s++)
{
    Console.WriteLine(tekst[s]);
}
//----------------Show all of array---------------------------//

//----------------Giv a number of column-----------------////
// try to use names with some meaning for variables, for example instead of "a" use "column" for the column 
Console.WriteLine("Podaj kolumne");
int column = Convert.ToInt32(Console.ReadLine());
// your result for zeros in a given column
int suma = 0;
// for each line in your string[]
foreach ( string line in tekst )
{
    // get the line separated by comas
    string[] lineColumns = line.Split(',');
    // check if that column is a zero, remember index is base 0
    if ( lineColumns[column-1] == "0" )
        suma++;
}
Console.WriteLine(suma);

编辑:只要确保他们要求的列确实存在于您的数组中，如果您不认为第一列是具有名称的列，请调整这部分

lineColumns[column] // instead of lineColumns[column-1]
