FluentValidation 是否具有开箱即用的错误级别？

Question

I would like to use the FluentValidation like this:

public class CustomValidator : AbstractValidator<Customer> {
  public CustomValidator()
  {
    RuleFor(obj => obj.Prop).NotNull().Level(ErrorLevels.Error);
    RuleFor(obj => obj.Prop).NotEqual("foo").Level(ErrorLevels.Warning);
  }
}

Are there any tools for this? The documentation does not contain information about this.

Answer 1

As you say, the docs don't seem to mention it but it looks like you can use .WithSeverity(Severity.Error) where Severity is an enumeration (enum) with values of Error , Warning and Info

public class CustomValidator : AbstractValidator<Customer> {
  public CustomValidator()
  {
    RuleFor(obj => obj.Prop).NotNull().WithSeverity(Severity.Error);
    RuleFor(obj => obj.Prop).NotEqual("foo").WithSeverity(Severity.Warning);
  }
}

Hope this helps!

Note that Severity is only informational ; IsValid will still return false for Warning and Info severity.
