Why type “int” is never equal to 'null'?

Question

int n == 0;

if (n == null)    
{  
    Console.WriteLine(\"......\");  
}

Is it true that the result of expression (n == null) is alw

Answer 1

In C# using an uninitialized variable is not allowed.

So

int i;
Console.Writeline(i);

Results in a compilation error.

You can initialize int with new such as:

int anInt = new int();

This will result in the Default value for int which is 0. In cases where you do wish to have a generic int one can make the int nullable with the syntax

int? nullableInt = null;
