Why do we need a getter for just for example getting the field of an object in C#? Setter makes sense to me for its purpose, for example, to validate data, or add some algorithm when changing a field. I mean if we are going to get the value of the field, just make a public field and done.

Not sure what you are getting out but tell me how this might relate

public record Person(  
    [property: Description("Key")] int Id,  
    [property: Description("First Name")] string FirstName,  
    [property: Description("Middle Name")] string MiddleName,  
    [property: Description("Last Name")] string LastName  
);

---

(int id, string firstName, string middleName, string lastName) =   
    new Person(1,"Karen", "", "Payne");  
  
Console.WriteLine($"{id}, {firstName}, {middleName}, {lastName}");

If you make a public field to get its value, then you can also set its value directly, by-passing the setter that validates the data. You probably do not want this.

Hi @Dat Pham , Can you be more specific about the problem you're having? Please take a look at the related materials Get and [The get accessor](https://learn.microsoft. com/en-us/dotnet/csharp/programming-guide/classes-and-structs/using-properties#the-get-accessor). And check out karen's comment. Please let me know if there are any updates.
