Check data correctness before export to xml in C#

I have class like that:

public class Animal

[Required]
[StringLength(20)]
public string Name get; set;
public double Weight get; set;
public double Height get; set;
public int AnimalID get; set;



and I have to generate XML using this, but before it, I have to check correctness of this data (e.g. Weight cannot be longer than 100, AnimalID should be in range 0 to 9).

Weight

AnimalID

How should I do this?

I have blackout...

You can use DataAnnotations from DataAnnotations namespace. This way you can wrap the object in try/catch block like below and catch
ValidationExceptions:

try
Animal animal = GetAnimal();
catch(ValidationException ex)


public class Animal

[Required]
[StringLength(20)]
public string Name get; set;
[Required, RangeAttribute(0,100)]
public double Weight get; set;
public double Height get; set;
[Required, RangeAttribute(0, 9)]
public int AnimalID get; set;



Also, if you are using MVC then you can use methods like ModelState.IsValid etc.
