how to convert type string to int

Question

I have created some classes and in one instance, I want the programme to read the answer (numeric). I have tried to set the class as string and as int but continue to have problems. Please bear with me I am just starting to learn programming.

public **int** Age { get; set; }
Animal cuddle = new Animal();
            cuddle.Color = "";
            cuddle.Age = 0;
            cuddle.Name = "";
            cuddle.Type = "";
Console.WriteLine("Hi, {0} How old do you want your {1,2} to be?\n Remember, if your {3} is older then 5 you will have to give her double!!!", name, cuddle.Color, player);
            cuddle.Age = **Console.ReadLine**();
            if (cuddle.Age < 5)
            {

In this instance it doesn't accept the Console.ReadLine. If I change the int to string as:

 public **string** Age { get; set; }

then it doesn't accept

if (**cuddle.Age < 5**)

I have tried without the brackets and/or with (**cuddle.Age = < 5**)

int age = 0;
if(int.TryParse(Console.ReadLine(), out age)) //It can be parsed as integer:
{
     if(age < 5)
     {
        // do your work
     }
}

You can go further more and repeat reading line while the input is not parse-able:

int age = 0;
while(!int.TryParse(Console.ReadLine(), out age));
if(age < 5)
{
   // do your work
}

Here is the DEMO

Thanks Ashkan. It didn't show any errors but it didn't work at the end. It shut me out when this question was answered. Can you help me? – Itzik Sep 09 '17 at 21:25

You can cast to an int, on user input:

int theInt = Convert.ToInt32(Console.ReadLine());

This is possibly a duplicate of this question: Reading an integer from user input
