How To Pass Different Objects to same Function in C#

Question

I have 10 different classes, but below are two for the purpose of this question :

public class Car
{
    public int CarId {get;set;}
    public string Name {get;set;}
}

public class Lorry
{
    public int LorryId {get;set;}
    public string Name {get;set;}
}

Now I have a function like

public static object MyFunction(object oObject, string sJson)
{
    //do something with the object like below 
    List<oObject> oTempObject= new List<oObject>();
    oTempObject = JsonConvert.DeserializeObject<List<oObject>>(sJson);
    return oTempObject;
}

What I'm wanting to do is pass the object I create like (oCar) below to the function.

Car oCar = new Car();

My question is how can I pass a object of a different type to the same function ?

Answer 1

Using generic methods will solve the trick:

public static List<T> MyFunction<T>(string sJson)
{
    //do something with the object like below 
    return (List<T>)JsonConvert.DeserializeObject<List<T>>(sJson);
}

Usage:

List<Car> cars = MyFunction<Car>(sJson);

or

List<Lorry> cars = MyFunction<Lorry>(sJson);

Update (thanks to Matthew for noticing the type behind the method name), btw: this is not needed when a parameter is type T.
