Let method take any data type in c#

Question

I have a lot of unit tests that pretty much tests the same behavior. However, data type changes.

I am trying to create a generic method that can take any data type.

Answer 1

Make your parameter type "object" and your method will accept every type as input. Then you can detect its type using GetType(), and even use tools like int.Parse, ToString(), and type casting to convert your input to a specific type and then work with it.

    static void whatsmytype(object place)  // Will accept any type
    {
        Type t = place.GetType(); // detects type of "place" object
        if (t.Equals(typeof(string)))
            Console.WriteLine("Type is string.");
        else if (t.Equals(typeof(int)))
            Console.WriteLine("Type is int.");
        else 
            Console.WriteLine("Type is unknown.");
    }

Edit: If readability is not really an issue, you could replace the method declaration line with code below, to get a minor speed improvement:

        static void whatsmytype(T place)
