events - Custom attribute in .NET to execute code before and after decorated method? -

-

ideally i'd find way like:

[mycustomattribute()] public void mymethod() {     debug.write("b"); }  public mycustomattribute : attribute {     public void onbegin()     {         debug.write("a");        }      public void onend()     {         debug.write("c");     } }

which write:

abc

when mymethod() gets excuted. ideas if can done? actionfilter attribute seems similar idea, applies mvc requests.

take @ postsharp - pretty already.

it post processor - takes compiled assembly, looks attributes , injects code decorated methods.

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
