dynamic class loadingIf someone has compiled a dll for the some classes, and I want to use the dll in another project, how can I know the class available in that dll file? Thanks!

foreach( Type t in a.GetTypes() ) { if( a.IsClass ) { // Do stuff to class such as object o = a.CreateInstance(t.FullName); } } Obviously if you are interested in all types not just classes you can omit the if. Regards Richard Blewett - DevelopMentor http://www.dotnetconsult.co.uk/weblog http://www.dotnetconsult.co.uk Hi all, If someone has compiled a dll for the some classes, and I want to use the dll in another project, how can I know the class available in that dll file? Thanks! Thanks!
How about even the name of the dll file is not provided? We only know the dll file is in a certain directory, say c:\temp, but the name of dll is not known.

{ try { Assembly a = Assembly.LoadFrom(fileName); // etc } catch( FileLoadException e) { // deal with the fact that some of the dlls may not be assemblies } } Regards Richard Blewett - DevelopMentor http://www.dotnetconsult.co.uk/weblog http://www.dotnetconsult.co.uk Thanks!
