What is the Object data type in programming?

In C#, the Object data type is the base class for all types. This means that any type — whether primitive (int, bool, etc.) or reference (classes, arrays) — implicitly inherits from Object. Thanks to this, variables of type object can be used to store values of any type.

For example, an object type variable can contain a number, a string, or an instance of a class. However, to work with specific methods or properties, type casting is necessary.

object obj = 42; // storing an integer
int number = (int)obj; // explicit cast back to int

The Object type provides basic methods such as ToString(), Equals(), GetHashCode(), and GetType(), which are available for all objects in C#.
