easy question but i still didnt understand after searching google: what is the point of ToString?

There is such method where you write in a class “public override ToString()” with curly braces open where you return stuff, whats the point of that?

record Foo(int Value, string Name)

        return $"The value of this foo named {Name} is {Value}.";
    }
}

var f = new Foo(69, "Bobbert");
Console.WriteLine(f); // converts to string implicitly
Console.WriteLine(f.ToString()); // and explicitly
Console.WriteLine($"Output is: '{f}'"); // works with interpolation
