The object class has the following members:
public class Object
{
public Object();
public extern Type GetType();
public virtual bool Equals (object obj);
public static bool Equals (object objA, object objB);
public static bool ReferenceEquals (object objA, object objB);
public virtual int GetHashCode();
public virtual string ToString();
protected override void Finalize();
protected extern object MemberwiseClone();
}
object(System.Object) is the super class for all types.
We can always cast to object.
using System;
class Rectangle{
}
class Program
{
static void Main(string[] args)
{
object o = new Rectangle();
}
}
