Setting Properties In Once Class, Accessing From Another

Question

Hi. My question is basically this:

If I set dynamic data from one class, can I access that same data from another class? Below is the rough pseudocode of what I am trying to do:

Public Class Person
{
  public string ID { get; set; }
  public string Name { get; set; }

}

And, I do the below:

Public Class SomeClass
{

   private void SomeMethod()
   {

        List<Person> p = new List<Person>();

         loop {
           p.Add(id[i], name[i]);
           Timer t = new Timer(); 
          t.Interval = 1000;
         }
}

Can I access the values set in SomeClass from SomeOtherClass such that:

Public SomeOtherClass
{

  private List<Person> SomeOtherMethod(string id)
  {
      // HERE, THE RESPONSE VALUES MAY CHANGE BASED ON
      // WHERE IN THE LOOP SomeClass.SomeMethod HAS SET
      // THE VALUES IN Person.

      var query = from p in Person
                  where p.ID == id
                  select p;

      return query.ToList();

  }

}

Thanks for your thoughts...

Answer 1

You can access the members (ID, Name) for those properties, since you declared them as public.

When you say "Person", you're referring to a Type - the Person type.

In order to access a member of a specific Person, you need to use an instance of Person.

Person thePersonInstance = new Person(5, "Joe");
thePersonInstance.ID = 3; // This is fine, since it's public

However, in your example, you would need to provide a specific collection of "Person" instances to your method in SomeOtherClass. Something like:

Public SomeOtherClass
{

    // You need to provide some collection of Person instances!
    public List<Person> SomeOtherMethod(string id, IEnumerable<Person> people)
    {
        var query = from p in people
              where p.ID == id
              select p;

        return query.ToList();
    }
}

You could then use this somewhere else, like:

void SomeMethod()
{
      List<Person> people = new List<Person>();
      people.Add(new Person(1, "Name1");
      people.Add(new Person(2, "Name2");

      SomeOtherClass other = new SomeOtherClass();
      List<Person> filteredPeople = other.SomeOtherMethod(1);
 }
