c# - How to get a list of the implement rules - FluentValidations -

using fluentvalidation webapi, attempting show rules implemented on property.

i using microsoft.aspnet.webapi.helppage assemblies generate pages api. able enumerate validation rules can display attributes required , length on pages.

previously, custom attribute following:

-- namespace myapi.areas.helppage.modeldescriptions  private readonly idictionary<type, func<object, string>> annotationtextgenerator =     new dictionary<type, func<object, string>>     {         { typeof(myattribute), => "my attribute documentation" }     }; 

this add text required in additional information section of page. in event of using fluentvalidation, required type no longer set. rulefor(x => x.myproperty).notempty();

if helpful, code documenting annotations below:

-- namespace myapi.areas.helppage.modeldescriptions /// <summary>   generates annotations. </summary> /// <param name="property">         property. </param> /// <param name="propertymodel">    property model. </param> private void generateannotations(memberinfo property, parameterdescription propertymodel) {     var annotations = new list<parameterannotation>();      var attributes = property.getcustomattributes();     foreach (var attribute in attributes)     {         func<object, string> textgenerator;         if (annotationtextgenerator.trygetvalue(attribute.gettype(), out textgenerator))         {             annotations.add(                 new parameterannotation                 {                     annotationattribute = attribute,                     documentation = textgenerator(attribute)                 });         }     }      // rearrange annotations     annotations.sort(         (x, y) =>         {             // special-case requiredattribute shows on top             if (x.annotationattribute requiredattribute)             {                 return -1;             }             if (y.annotationattribute requiredattribute)             {                 return 1;             }              // sort rest based on alphabetic order of documentation             return string.compare(x.documentation, y.documentation, stringcomparison.ordinalignorecase);         });      foreach (var annotation in annotations)     {         propertymodel.annotations.add(annotation);     } } 

when calling generateannotations routine add logic @ property , fluent attributes assigned , add text.

maybe somehow use fluentvalidation.internal.propertyrules elegantly enumerate attributes?
