使用COM对象

作为.NET的补充，Powershell可以加载和访问COM对象。

查看可用的COM对象

每一个COM对象都有存储在注册表中的唯一标识符，想遍历访问可用的COM对象，可是直接访问注册表。

Dir REGISTRY::HKEY_CLASSES_ROOTCLSID  -include PROGID -recurse | foreach {$_.GetValue("")}
DAO.DBEngine.36
DAO.PrivateDBEngine.36
DAO.TableDef.36
DAO.Field.36
DAO.Index.36
PS C:Powershell> Dir REGISTRY::HKEY_CLASSES_ROOTCLSID -include PROGID -recurse
| foreach {$_.GetValue("")} | select -First 10
