class Program
{
static int age = 30;
static void Main(string[] args)
{
// Value Type
Console.WriteLine("Your birth year is {0}", ValBirthYear(age));
Console.WriteLine("if your age is {0}", age);
// Reference Type
Console.WriteLine("Your birth year is {0}", RefBirthYear(ref age));
Console.WriteLine("if your age is {0}", age);
Console.ReadKey();
}
//Function with value type parameter
private static string ValBirthYear( int Vage)
{
int year = DateTime.Now.Year - Vage;
Vage = year; //Assigning the calculated value to the parameter
return Convert.ToString(year);
}
//Function with reference type parameter. Notice the use of ref keyword.
private static string RefBirthYear(ref int Rage)
{
int year = DateTime.Now.Year - Rage;
Rage = year; //Assigning the calculated value to the parameter
return Convert.ToString(Rage);
}
}

Output (Value Type)
Your birth year is 1980
If your age is 30
Output (Ref Type)
Your birth year is 1980
If your age is 1980
