Question If num1 is not decimal then...

[Junes]

Hi,
So i want to make a calculator and if the number is not decimal it should say something like please type in a decimal number or something like that.
Thats my code:

if (num1 is !decimal)
{
    Console.WriteLine("Please type in a Decimal number");
}

            if (decimal.TryParse(Console.ReadLine(), out decimal decimal_Number))
                Console.WriteLine($"{decimal_Number} Is a decimal");
            else
                Console.WriteLine("Please type in a Decimal number");

Decimal.TryParse Method (System)

Converts the string representation of a number to its Decimal equivalent. A return value indicates whether the conversion succeeded or failed.
