c# - 按日期时间对 DirectorySearcher 查询的结果进行排序

Question

我有以下代码:

// Declare new DirectoryEntry and DirectorySearcher
DirectoryEntry domainRoot = new DirectoryEntry("LDAP://rootDSE");
string rootOfDomain = domainRoot.Properties["rootDomainNamingContext"].Value.ToString();
DirectorySearcher dsSearch = new DirectorySearcher(rootOfDomain);

// Set the properties of the DirectorySearcher
dsSearch.Filter = "(objectClass=Computer)";
dsSearch.PropertiesToLoad.Add("whenCreated");
dsSearch.PropertiesToLoad.Add("description");
dsSearch.PropertiesToLoad.Add("operatingSystem");
dsSearch.PropertiesToLoad.Add("name");

// Execute the search
SearchResultCollection computersFound = dsSearch.FindAll();

我想按 whenCreated 属性对结果进行降序排序，以便最新的计算机对象位于顶部。

我不能简单地做:

SortOption sortedResults = new SortOption("whenCreated", SortDirection.Descending);
dsSearch.Sort = sortedResults;

因为服务器返回错误(http://social.technet.microsoft.com/Forums/en-US/winserverDS/thread/183a8f2c-0cf7-4081-9110-4cf41b91dcbf/)

最好的排序方式是什么？

Answer 1

您可以按照 MSDN here 中的说明在服务器端执行此操作:

      new DirectorySearcher(entry)
      {
        Sort = new SortOption("cn", SortDirection.Ascending),
        PropertiesToLoad = {"cn"}
      };
