Question

I’m making a simple registration application and I have an assignment to learn more about lists. I have an assignment that says that i am to create a class called Persons and in that class set the values from the text fields in variables and add this to a list of type Person.

So far:

In the Person class:

string strSocialSecurityNumber = string.Empty;//---( This will not be used now.)
string strFirstName = string.Empty;
string strLastName = string.Empty;
string strFullName = string.Empty;
string strAge = string.Empty;
string strAll = string.Empty;
int intAge = 0;
List<Person> lstPerson = new List<Person>();

public void SetValues(string FirstName, string LastName, int Age)
{
    strFirstName = FirstName;
    strLastName = LastName;
    strFullName = strFirstName + " " + strLastName;
    intAge = Age;
    strAge = Convert.ToString(intAge);
    strAll = strAge + " " + strFullName;

}

public List<Person> Person()
{
    lstPerson.Add(strAll);
    return lstPerson;
}

Error message:
“can not convert from string to Person”

The assignment says that the list is to be of the type Person so I am supposed to add strings to it. I’ve looked how to do this but I don’t know how. I have seen that there are options like “ConvertAll” But I’m not sure if I am allowed to use it since the list should be of type Person.

Both having a list of Person and all the properties in the Person class i a little confusing.
I think the teacher meant that you should create a Persons class containing a list of Person.

public class Person
{
    public string strFirstName;
    ...
}

public class Persons
{
    List<Person> lstPersons = new List<Person>();

    public void AddPerson(string FirstName, ...)
    {
        Person person = new Person();
        person.strFirstName = FirstName;
        ...
        lstPersons.Add(person);
    }
}

I believe that this is more like what the assignment is requesting.
