fluentvalidation

I am using FluentValidation and I want to format a message with some of the object's properties value. The problem is I have very little experience with expressions and delegates in C#. FluentValidation already provides a way to do this with format arguments. RuleFor(x => x.Name).NotEmpty() .WithMessage("The name {1} is not valid for Id {0}", x => x.Id, x => x.Name); I would like to do something like this to avoid having to change the message string if I change the order of the parameters. RuleFor(x => x.Name).NotEmpty() .WithMessage("The name {Name} is not valid for Id {Id}", x => new { Id =

I have a FluentValidator that has multiple properties like zip and county etc. I want to create a rule that takes two properties just like a RuleFor construct public class FooArgs { public string Zip { get; set; } public System.Guid CountyId { get; set; } } public class FooValidator : AbstractValidator<FooArgs> { RuleFor(m => m.CountyId).Must(ValidZipCounty).WithMessage("wrong Zip County"); } This works but I want to pass both Zip and county to the rue in order to validate. What is the best method to achieve this? bpruitt-goddard There is a Must overload that also provides you with the FooArgs

I'm using Fluent Validation with the Ninject.Web.Mvc.FluentValidation library to automatically wire up all of my validators (and use dependency injection to create the validators). I created the following Models: public class Parent { public string Name { get; set; } public Child Child1 { get; set; } public Child Child2 { get; set; } } public class Child { public string ChildProperty { get; set; } } With the following validators: public class ParentValidator : AbstractValidator<Parent> { public ParentValidator() { RuleFor(model => model.Name).NotEmpty(); RuleFor(model => model.Child1)

I am able to register FluentValidation AbstractValidators using a FluentValidatorFactory . However, it doesn't feel right, because not all of the IoC container registrations happen during bootstrap / composition root. Instead, the fluent validators are registered by a separate factory : The composition root : public class SimpleDependencyInjector : IServiceProvider { public readonly Container Container; public SimpleDependencyInjector() { Container = Bootstrap(); } internal Container Bootstrap() { var container = new Container(); container.Register< // ...register all non-fluent-validator

In MVC, I can create a Model Validator which can take Dependencies. I normally use FluentValidation for this. This allows me to, for example, check on account registration that an e-mail address hasn't been used (NB: This is a simplified example!): public class RegisterModelValidator : AbstractValidator<RegisterModel> { private readonly MyContext _context; public RegisterModelValidator(MyContext context) { _context = context; } public override ValidationResult Validate(ValidationContext<RegisterModel> context) { var result = base.Validate(context); if (context.Accounts.Any(acc => acc.Email ==

i'm defining a validation for my Request objects. I would like the validator to stop on the very first failure, not only the one on the same chain. In the example below, if my TechnicalHeader object is null, i get a NullReference exception when the validation reaches the rule for TechnicalHeader.MCUserid . In poor words, i would like to do a conditional validation over the last three rules in the code below, according to the result of the first rule using System; using ServiceStack.FluentValidation; using MyProj.Services.Models; namespace MyProj.Services.BaseService.Validators { public class
