Validate Bool using Fluent Validator

Question

I want to validate a bool property using fluent validator. Which method should I use?

.NotNull() and .NotEmpty() functions didn't work.

Thanks.

Answer 1

You should use .NotNull().

NotEmpty() will take only true as valid property. NotNull() will take both true and false as valid properties.

Answer 2

In order to validate a boolean using fluent validator:

Create the following rule

            RuleFor(x => x.BooleanProperty)
            .Must(ValidateBoolean)
            .WithErrorCode("Boolean Validation Failed");

Define the predicate validator

        private bool ValidateBoolean(T arg1, bool arg2, PropertyValidatorContext arg3)
    {
        // validate arg2, return true if validation successful or false if failed
        throw new System.NotImplementedException();
    }
