推荐答案

我知道这个职位是很老，但我一直在用同样的问题作斗争

I know this post is quite old, but I've been battling with the same issue.

我最终设法解决它，我希望下面的代码可以帮助别人：

I eventually managed to solve it and I hope the code below helps someone:

        using(var ds = new DirectorySearcher())
        {
            ds.SearchRoot = new DirectoryEntry("");
            ds.Filter = "(|(&(objectCategory=printQueue)(name=*)))";

            ds.PropertiesToLoad.Add("printername");
            ds.PropertiesToLoad.Add("portname");
            ds.PropertiesToLoad.Add("servername");
            ds.PropertiesToLoad.Add("cn");
            ds.PropertiesToLoad.Add("name");
            ds.PropertiesToLoad.Add("printsharename");
            ds.ReferralChasing = ReferralChasingOption.None;
            ds.Sort = new SortOption("name", SortDirection.Descending);

            using(var src = ds.FindAll())
            {
                foreach(SearchResult sr in src)
                {
                    Console.WriteLine("------------------------------------");
                    Console.WriteLine(sr.GetDirectoryEntry().Name);
                    foreach (DictionaryEntry p in sr.Properties)
                    {
                        var propName = p.Key;
                        var propCollection = (ResultPropertyValueCollection)p.Value;
                        var propValue = propCollection.Count > 0 ? propCollection[0] : "";
                        Console.WriteLine(propName);
                        Console.WriteLine(propValue);
                    }
                    Console.WriteLine("------------------------------------");                        

                }

            }

        }

如果您想返回所有属性，看看有什么可用然后只需注释掉ds.PropertiesToLoad线，这将使你的完整列表。

If you want to return all the properties to see what's available then just comment out the ds.PropertiesToLoad lines and that will give you the full list.
