How to assign values to an IEnumerable

I have the following class in which I have an IEnumerable list as follows

public class Orders
{
    public string No { get; set; }
    public string Id { get; set; }
    public IEnumerable<string> OrderTypes { get; set; } = new List<string> { "order 1", "order 2", "order 3" }
}

Instead of me assigning the values directly above is there a way i can put it in a separate class as follows

public class OrderTypes()
{
    IEnumerable<string> myEnumerable = new List<string>()
    myEnumerable.add("Order 1")
    myEnumerable.add("Order 3")
    myEnumerable.add("Order 4")
    myEnumerable.add("Order 5")
    myEnumerable.add("Order 6")
}

And then call this function above like

public class Orders
{
     public string No { get; set; }
     public string Id { get; set; }
     public IEnumerable<string> OrderTypes { get; set; } = OrderTypes
}

The reason for this is cause my list gets too long and it would be easier to view, but I'm not sure how to achieve this.

Close enough. You can simply use a static method:

public class Orders
{
  public string No {get;set;}
  public string Id {get;set;}
  public IEnumerable<string> OrderTypes{get;set;} = CreateOrderTypes();

  private static IEnumerable<string> CreateOrderTypes()
  {
     return new List<string>
     {
       "Order 1",
       "Order 3",
       "Order 4",
       "Order 5",
       "Order 6",
     };
   }
}

Of course, the CreateOrderTypes does not have to be in the same class and can be moved to a different class. The second class has to be visible to the first one.

public class Orders
{
  public string No {get;set;}
  public string Id {get;set;}
  public IEnumerable<string> OrderTypes{get;set;} = OrderTypesFactory.InitOrderTypes();
}

static class OrderTypesFactory
{
  static IEnumerable<string> InitOrderTypes()
  {
     return new List<string>
     {
       "Order 1",
       "Order 3",
       "Order 4",
       "Order 5",
       "Order 6",
     };
   }
}

If I understand the question correctly, you could have a constructor for class Orders and then when you instantiate the class, you could pass a value of IEnumerable inside it and assign that value. So it would look something like:

public class Orders
{
    public string No { get; set; }
    public string Id { get; set; }
    public IEnumerable<string> OrderTypes { get; set; }

    public Orders(IEnumerable<string> orderTypes)
    {
        OrderTypes = orderTypes;
    }

}

public class Main
{
    public void Main()
    {
        var orderTypes = new List<string>() { "Your", "values", "Here" };
        var orders = new Orders(orderTypes);
    }
}
