I have coded every line with appropriate things, however, I received an error when I tested after selecting one of the five options from the menu which is prompting the user to choose it for register dog and so on. Therefore, I am unable to recognize any wrong with my code yet I did debug and tested it many times. I do not know what to do with it even though I checked to ensure every case is not overlapped without having a "break;".

                break;
        }
    }

void ShowDogInfo(Dog dog)
{
    Console.WriteLine("Name: {0}", dog.Name);
    Console.WriteLine("Breed: {0}", dog.Breed);
    Console.WriteLine("Age: {0}", dog.Age);
    Console.WriteLine("Vaccine: {0}", dog.Vaccine);
    Console.WriteLine();
}

I am expecting that the result will show the Console.WriteLine() if the input is successfully added or removed. I also am expecting to show all list of dogs if the user select 4 otherwise they can select 5 (i have tested and it works in which it exits from the program).

I have re-examined all lines so I do not see any wrong with it unless I have someone who might spot that I have missed something.

CodePudding user response：

Name = value;: in the setter, you call the setter, which calls the setter etc. This results in the observed stack overflow.

Change your properties to auto-properties:

public class Dog
{
    public string Name { get; set; }
// etc.
}
