QuestionHow can a method return a validation result Pin

Membercodecs112-Mar-21 19:54 
Assume there is a method which return the query result List<Student>
List<Student> FindStudents(StudentCriteria sc);
in which the StudentCriteria is a model for passing the search information:
public class StudentCriteria
{
    public string Name { set; get; }
    public int? Age { set; get; }
    public DateTime? BeginRegisterDate { set; get; }
    public DateTime? EndRegisterDate { set; get; }
}
Moveover, we should validate the input parameter StudentCriteria , so we call the following method in FindStudents(...)
ValidationResult Validate(StudentCriteria sc);
in which ValidationResult is an object representing the validation result, something like that:
public class ValidationResult
{
    public bool Success { set; get; }
    public List<String> ErrorInfo { set; get; }
}
All 'Error' information will be contained in ValidationResult and return to FindStudents(...) if Validate(...) finds any problem in StudentCriteria sc:
such as Age is negative int, EndRegisterDate is before BegionRegisterDate...

But, how can FindStudents(...) return the ValidationResult to the caller?

-----Someone may consider that FindStudents(...) throws ArgumentException to the caller if StudentCriteria sc is invalid....

However, I think Exceptions are for exceptional circumstances
