如何使用 FluentValidation 同时为多个字段创建规则

Question

我需要验证 Asp.net MVC 项目中的以下情况：如果字段 ServicoEmail、ServicoWebsite、ServicoBlog、ServicoRedeSocial 和 ServicoMensagemInstantanea 都是假的，return 一条错误消息。我尝试按以下方式进行操作，但它不起作用...有人知道如何帮助我吗？

RuleFor(ps => new { ps.ServicoEmail, ps.ServicoWebsite, ps.ServicoBlog, ps.ServicoRedeSocial, ps.ServicoMensagemInstantanea })
    .Must(ps=> ps.ServicoEmail == false && ps.ServicoWebsite == false && ps.ServicoBlog == false && ps.ServicoRedeSocial == false && ps.ServicoMensagemInstantanea == false)
    .WithMessage("É necessário selecionar pelo menos um Tipo de Serviço.");

我的Class:

public abstract class ServicoWebCommand : Command
{
    public int Id { get; protected set; }

    public string Descricao { get; protected set; }

    public string FormatoCampo { get; protected set; }

    public bool ServicoEmail { get; protected set; }

    public bool ServicoWebsite { get; protected set; }

    public bool ServicoBlog { get; protected set; }

    public bool ServicoRedeSocial { get; protected set; }

    public bool ServicoMensagemInstantanea { get; protected set; }

    public bool PadraoSistema { get; protected set; }
}

您需要单独指定它们中的每一个，或者您可以指定自定义验证器。

方式一：

RuleFor(ps => ps).SetValidator(new ServicoValidator());

然后编写Validator实现：

public class ServicoValidator: AbstractValidator<ServicoWebCommand>
{
    public ServicoValidator()
    {
        RuleFor(t => t).Custom(ValidateServico);
    }


    private void ValidateServico(ServicoWebCommand ps, CustomContext validationContext)
    {
        if(ps.ServicoEmail == false && 
           ps.ServicoWebsite == false && 
           ps.ServicoBlog == false && 
           ps.ServicoRedeSocial == false && 
           ps.ServicoMensagemInstantanea == false)
         {
           validationContext.AddFailure("É necessário selecionar pelo menos um Tipo de Serviço.");
         }
    }
}

方式二：

RuleFor(ps => ps).Must(ps => Validate(ps));

并编写验证方法，如：

private bool Validate(ServicoWebCommand ps)
{
    if(ps.ServicoEmail == false && 
       ps.ServicoWebsite == false && 
       ps.ServicoBlog == false && 
       ps.ServicoRedeSocial == false && 
       ps.ServicoMensagemInstantanea == false) 
        return false;

    return true;
}
