• Every class in C# inherits the property of the Object class implicitly that is., the Object class is the superclass or super most class of each and every class.

using System;
class Base:Object {
  public static void Main() 
  {
    //using this class we can access all the properties of Base class and Object class.
  }
}

Note: Even if we didn't inherit the Object class explicitly then also the compiler will implicitly inherit the Object class to all the class.

• If some class is inheriting properties of other class then that class will not implicitly inherit the Object class because C# doesn't support the multiple inheritances.

using System;

class Super {
  //This class will inherit the Object class implicitly.
}

class Base:Super, Object {
  public static void Main() 
  {
    //This class inherited the Superclass and we can't inherit implicitly or explicitly the Object class.
  }
}

• We have some useful methods in the Object class which we can use in our program.

Methods of Object class :

Equals(Object): Determines whether the specified object is equal to the current object.

Equals(Object, Object): Determines whether the specified object instances are considered equal.

Finalize(): Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

GetHashCode(): Serves as the default hash function.

GetType(): Gets the Type of the current instance.

MemberwiseClone(): Creates a shallow copy of the current Object.

ReferenceEquals(Object, Object): Determines whether the specified Object instances are the same instance.

ToString(): Returns a string that represents the current object.

Overriding methods of Object class :

• The Object class has multiple methods but we can only override three methods from the Object class.

• GetHashCode(), Equals(Object), and ToString() only these methods of the Object class can be overridden by the programmer.
