namespace ClassValidation
{
    public class Student
    {
        [Required(ErrorMessage = "Name is required")]
        public String Firstname;


        [Required(ErrorMessage = "Email is required")]
        public String personalEmail;


            }
}


private static void Main(string[] args)
        {

            Student student = new Student();
            student.personalEmail = "del";


            ValidationContext context = new ValidationContext(student, null, null);
            List<ValidationResult> results = new List<ValidationResult>();
            bool valid = Validator.TryValidateObject(student, context, results, true);

            if (!valid)
            {
                foreach (ValidationResult vr in results)
                {
                    Console.ForegroundColor = ConsoleColor.Red;
                    Console.Write("   ::  {0}{1}", vr.ErrorMessage, Environment.NewLine);

                }

            }
        }

Answer 1

The validator ignores the [RequiredAttribute] on fields - it takes into an account only properties; so for purposes of Validator.Validate - change your class to:

public class Student
{
  [Required(ErrorMessage = "Name is required")]
  public String Firstname { get; set; }


  [Required(ErrorMessage = "Email is required")]
  public String personalEmail { get; set; }
}
