MaxLength Validator
Ensures that the length of a particular string property is no longer than the specified value.
Only valid on string properties
String format args:
{PropertyName} = The name of the property being validated
{MaxLength} = Maximum length
{TotalLength} = Number of characters entered
{PropertyValue} = The current value of the property
MinLength Validator
Ensures that the length of a particular string property is longer than the specified value.
Only valid on string properties
{PropertyName} = The name of the property being validated
{MinLength} = Minimum length
{TotalLength} = Number of characters entered
{PropertyValue} = The current value of the property
Example
static void Main(string[] args){
List errors = new List();
PersonModel person = new PersonModel();
person.FirstName = "TestUser444";
person.LastName = "TTT";
PersonValidator validator = new PersonValidator();
ValidationResult results = validator.Validate(person);
if (results.IsValid == false){
foreach (ValidationFailure failure in results.Errors){
errors.Add(failure.ErrorMessage);
}
}
foreach (var item in errors){
Console.WriteLine(item);
}
Console.ReadLine();
}
}
public class PersonModel{
public string FirstName { get; set; }
public string LastName { get; set; }
}
public class PersonValidator : AbstractValidator{
public PersonValidator(){
RuleFor(p => p.FirstName).MaximumLength(7).WithMessage("MaximumLength must be 7 {PropertyName}") ;
RuleFor(p => p.LastName).MinimumLength(5).WithMessage("MinimumLength must be 5 {PropertyName}");
}
}
