Question

Is it possible to access an attribute’s properties from within the item to which it’s applied (e.g. a method)? For example, with the code below, could I access a property on the “RequiresConnection” attribute from with the “Search” method?

    [RequiresConnection]
    public SearchResult Search(SearchInfo searchInfo)
    {
    }

Answer 1

Sure

class TheClass {
  [RequiresConnection]
  public SearchResult Search(SearchInfo searchInfo) {
    MethodInfo methodInfo = typeof(TheClass).GetMethod("Search");
    RequiresConnection attrib = (RequiresConnection).methodInfo.GetCustomAttributes(
      typeof(RequiresConnection),
      false)[0];
