I have model with two values: string id and string subject. I am saving it variable a. now i want to pass only id to a method when i have some data in variable a. How to do this?

If I understand this correctly, you have a model which well call Model

public class Model {
    public string ID;
    public string Subject;
}

and you want to store it as such public Model a;.

You want to pass ID from a as a parameter in a method.

You could do one of the following, would suggest first, in case the requirement changes to require subject.

public void DoSomething(Model model) {
    string id = model.ID; // Now you have just the ID

    // Do something with the ID
}

or

public void DoSomething(string id) {  // this is a bit ambiguous though as to purpose
    // Do something with the ID
}
