c# - How to read names and versions of assemblies -

i have create application read name of dlls (assemblies) in application path along version. , read same of dll in sub folders.

how in c#. can 1 me sample code?

edit : how read details of legacy dlls( external dlls- not created in .net)

thanks in advance.

you should search through given root directory calling directory.getfiles(). can run through result , load every assembly calling assembly.reflectiononlyloadfrom() (cause if load way won't added appdomain, thous no unload needed).

with these assembly classes can access getname() function , take version property version information.

other properties, not get, can reached through getcustomattribute() function this:

((assemblycopyrightattribute)assembly.getcustomattribute(typeof(assemblycopyrightattribute), true).copyright 

with these informations should able built list like.

update:

and here's obligatory linq code sample:

var rootpath = @"c:\myroot\folder";  var query = directory.getfiles(rootpath, "*.dll", searchoption.alldirectories)                      .select(filename =>                      {                          try                          {                              return assembly.reflectiononlyloadfrom(filename);                          }                          catch                          {                              return null;                          }                      })                      .where(assembly => assembly != null)                      .select(assembly => new                      {                          version = assembly.getname().version.tostring(),                          name = assembly.getname().name                      });  foreach (var infos in query) {     console.writeline(infos.name + "   " + infos.version); } 

update 2:

so normal dlls should take this question.
