C# GetObjectByField_id ?

[guentherM]

hallo

I am a total c#-noob and have a little question. I'll try to put it in an example:

I have a class "Car" that has the fields "name" and wheels.
Wheels are from the type "Wheel".
The constructor of the Car-Class sets the name of the car-objekt and the id of the Wheel-Object.
Expect now, there are more cars, each with its wheels.
Now I want to do something like "getCarByWheel_id()":
All I have is the ID of one wheel and i want to get the object of the corresponding car.
You know what i mean?

class Car{
  string name;
  public Wheel Wheels;  
 
  public Car(string name, int wheel_id){
    this.name="mycar";
    this.Wheels = new Wheel();
    this.Wheels.Id= 1234;
  }
}
 
class Wheel{
  public int Id;
 
  public Wheel() { }
}

Thanks a lot for your help and have a nice weekend!
