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;".

string name2 = Console.ReadLine();
bool added = false;
for(int i = 0; i< dogs.Length; i++)

Dog dog = dogs[i];
if(dog!=null && dog.Name == name2)

}

dog.Vaccine = vac;

Console.WriteLine("{0} was successful added", vac);
break;

break;

Console.WriteLine("{0} was not found", name2);

break;
case 4:
bool listIsEmpty = true;
foreach(Dog dog in dogs)
{
if(dog != null)
{
ShowDogInfo(dog);
listIsEmpty = false;
}

if(listIsEmpty)

Console.WriteLine("No dogs in the list");
}
break;
case 5:
Console.WriteLine("Thank you for using Rochester Doggie System");

break;
default:
Console.WriteLine("Invalid selection");
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.
>Solution :
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.
}
