extension method for a method C# -

is there way have extension method on method? example method takes user object parameter , need security check if user can use method @ beginning of method. can method have extension method "check can user use me" , return bool.

thanks.

you can use aspect oriented programming (aop) implement cross-cutting security checks in code.

in .net have choice of several aop frameworks, example:

• spring.net
• postsharp

in particular postsharp documentation has some nice examples on how implement security using aop.
