c# – Difference between using typeof and is

Question:

In C#, when I need to check if a variable is of a certain type, I usually use the is operator:

if(qualquerVariavel is int)
    Console.Write("A variável é int");

I know it's also possible to check the type of a variable in other ways, one of which is using typeof :

if(qualquerVariavel.GetType() == typeof(int))
    Console.WriteLine("A variável é int");

What is the difference between these two operators? Are there others who "do the same thing" but with a little difference?

Answer:

• is checks the entire inheritance structure of the object;
• typeof() returns the exact type of the object.

To better illustrate:

class Animal { } 
class Cachorro : Animal { }

var a = new Cachorro();

Console.WriteLine(a.GetType() == typeof(Animal)) // false 
Console.WriteLine(a is Animal)                   // true 
Console.WriteLine(a.GetType() == typeof(Cachorro))    // true
