C＃将CSV添加到列表

Question

I try to add the containing of a csv file to a new list. It's a list of different types of people with caracteristics like the function, a matricule, the last name, the firstname and a sex. So I managed to read the file but I don't really know how to process to add the containing of the file to my list.Here is my code :

  `private static void ReadTest() 
    {
        int count = 0;
        string line;
        Char c = ';';

        StreamReader file= new StreamReader("Listing.csv");

        while ((line= file.ReadLine()) != null)
        {
            String[] substrings = line.Split(c);

            foreach (var substring in substrings)
            {
                Console.WriteLine(substring);
            }

            count++;
        }

        fichier.Close();
        System.Console.WriteLine("Number of lines : {0}.", count);
    }
    static void Main(string[] args)
    {
        List<Personnel> Workers = new List<Personnel>();

    }

Answer 1

Why don't you use CSVHelper , it will be as simple as the following:

var csv = new CsvReader( textReader );
var records = csv.GetRecords<Personnel>();
//then loop through
foreach( var record in records )
{

}

you just need to install the nuget package:

Install-Package CsvHelper

Check this for more information.

Answer 2

Replace the foreach loop with something like the following:

var person = new Personnel(); 
person.firstname = substrings[0];
person.lastname = substrings[1]; 
person.function = substrings[2]; 
//continue until all variables assigned. 
Workers.Add(person); 

Also, if the Workers list is not a static list, then make ReadTest return a List and create a list within the function.

Like this:

private static List<Personnel> ReadTest() 
{
    int count = 0;
    string line;
    Char c = ';';

    StreamReader file= new StreamReader("Listing.csv");
    var Workers = new List<Personnel>();

    while ((line= file.ReadLine()) != null)
    {
        String[] substrings = line.Split(c);

        var person = new Personnel(); 
        person.firstname = substrings[0];
        person.lastname = substrings[1]; 
        person.function = substrings[2]; 
        //continue until all variables assigned. 
        Workers.Add(person); 

        count++;
    }

    file.Close();
    System.Console.WriteLine("Number of lines : {0}.", count);
    return Workers; 
}
static void Main(string[] args)
{
    List<Personnel> Workers = ReadTest();

}
