Use IEnumerable method in other class C#

Well I have a class Person:

 public class Person
{
    public string firstName { get; set; }
    public string lastName { get; set; }
    public int age { get; set; }
    public IEnumerable<Person> GetPersons(string path)
    {
        var personlist = new List<Person>();
        var lines = System.IO.File.ReadAllLines(path);
        foreach (var line in lines)
        {
            var split = line.Split(";");
            var firstName = split[0];
            var lastName = split[1];
            var age = split[2];

            Person person = new Person
            {
                firstName = firstName,
                lastName = lastName,
                age = int.Parse(age),
            };
            personlist.Add(person);
        }

        return personlist;
    }
}

And in my Main method I'd like to asign the method GetPersons(string path) to a list

var list = new List<Person>();
list = GetPersons("persons.csv");

I does not compile with error CS0103: The name 'GetPersons' does not exist in the current context

You've made GetPersons an instance method which means you'd need an instance of a Person to call it - this doesnt quite make sense for what you're doing.

There is some sense in making it static:

public class Person
{    
    public static IEnumerable<Person> GetPersons(string path)
    {
        // ... //
    }
}

Then call it as:

var list = Person.GetPersons("persons.csv");

But you should consider if the Person class is the correct place for this code.

you need to create a new instance of Person class and then call GetPersons. Try like:

var list = new List<Person>();
var person = new Person();
list = person.GetPersons("persons.csv");
