如何使用System.DirectoryServices.ActiveDirectory.Domain类获取域别名

我们有一个全名域名，例如long-domainname.com ; 此域名将替换为别名short 。 可以使用netapi32.dll检索此别名，如下所示：

 [DllImport("Netapi32.dll")] static extern int NetApiBufferFree(IntPtr Buffer); // Returns the domain name the computer is joined to, or "" if not joined. public static string GetJoinedDomain() { int result = 0; string domain = null; IntPtr pDomain = IntPtr.Zero; NetJoinStatus status = NetJoinStatus.NetSetupUnknownStatus; try { result = NetGetJoinInformation(null, out pDomain, out status); if (result == ErrorSuccess && status == NetJoinStatus.NetSetupDomainName) { domain = Marshal.PtrToStringAuto(pDomain); } } finally { if (pDomain != IntPtr.Zero) NetApiBufferFree(pDomain); } if (domain == null) domain = ""; return domain; } 

此方法返回排序值。 但是使用System.DirectoryServices.ActiveDirectory.Domain类及其Name属性，我得到long-domainname.com值。 在调试模式下搜索属性，我找不到任何短值字段或属性。 是否可以使用System.DirectoryServices.ActiveDirectory.Domain类？ 或者可能有一些其他类的System.DirectoryServices命名空间？ 如何在不导入外部* .dll的情况下获取短域名值？
