c# - Fluent Validation - Stop validating all other validations when a specific validation fails -

i'm using fluent validation server side validation. i've created set of rules validated. these rules individual functions in validator.

 public samplevalidator() {             validate_authorisation();             validatetitle_notempty();             validategender_notempty();             validatefirstname_regex();             validatefirstname_notempty();             validatesurname_notempty();             validatesurname_regex();             validatemobilephone_regex(); }  private void validate_authorisation()         {             rulefor(model=> model)                 .must(model=> isuserauthorised(username))                 .withname("authorisation check");         }   private void validatetitle_notempty()         {             rulefor(model=> model)             .must(title=> !string.isnullorempty(title))             .withname("title");              }         private void validategender_notempty()         {             rulefor(model=> model)               .must(gender=> !string.isnullorempty(gender))                .withname("gender");         }.... , others 

now, want stop validating other validations when authorisation validation fails. don't want use cascademode.stoponfirstfailure because checks first validation failure , stop validating others. there way return service (from validator called) when authorisation validation fails.

if change validate_authorisation method following:

private irulebuilderoptions<model, string> validate_authorisation() {     rulefor(model=> model)         .must(model=> isuserauthorised(username))         .withname("authorisation check"); } 

you can following using dependentrules extension method:

validate_authorisation().dependentrules(rules => {     validatetitle_notempty();     validategender_notempty();     validatefirstname_regex();     validatefirstname_notempty();     validatesurname_notempty();     validatesurname_regex();     validatemobilephone_regex();  });
