How do I update Sample Data in C#?

I have this sample data. Right now it is defined in a seperate C# file like this:
public class SampleData
{

public static ObservableCollection<Product> GetSampleData()
{
ObservableCollection<Product> teams = new ObservableCollection<Product>();
}
}

and I load the obsevableCollection inside GetSampleData().

It works and I am able to get the sample data anywhere in my program.

But how can I redesign this code so that I can create the sample data on the fly from outside the class?

There's not enough information here to give a meaningful response. Can you give more details? Maybe an example of how you'd like to call this method?
