.NET Forum / .NET Framework / New Users / June 2006compile-time error generating custom attributes
hi all, can I create my own compile-time attributes? e.g. an attribute applied to a method and that will generate a compile time error if the method has the wrong signature? I was hinted twords 'Intellisense API' but cant seem to find it at all... thanx, Picho New/Custom attributes that you created would not be understood by Visual Studio / Compiler.. Specific to your case, where do you wish to apply this attribute -- checking the method signature?

I would like to avoid run-time errors caused by objects that apply my attributes to their class members. I could have used simply interfaces but I need more info on the members such as descriptions, and other things. plus I wish to avoid the need of implementing my interface AND applying attributes. when I apply an attribute that is defined to target a method to a property, i get a compilation error right? cant I extend this and create attributes that will validate certains constrains and produce compile-time errors? > New/Custom attributes that you created would not be understood by Visual > Studio / Compiler..

You probably do want both... method calls through interfaces are many times faster than reflection on attributes and a reflected call. > when I apply an attribute that is defined to target a method to a > property, i get a compilation error right?

Define attributes.... do both. The implementation class can be discovered dynamically using reflection (say from config files). Use the reference to the implementation for all uses. Whenever required, reflect on the class to find attribute values.
