c# and date property

[Anonymous]

How i can get date value from property?

I can get string type, but other type throw "COM..." exception.

public DateTime CreationDate
{
   get
   {

      try
      {
        return Sets["Design Tracking Properties"]
           [Inventor.PropertiesForDesignTrackingPropertiesEnum.kCreationDateDesignTrackingProperties].Value;
      }
      catch 
      { ... }

   }
}
