我们有一个全名域名，例如long-domainname.com；此域名替换为别名short。可以使用 检索此别名netapi32.dll，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该类及其Name属性，我得到了 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。System.DirectoryServices.ActiveDirectory.Domain上课可以吗？或者可能有其他类的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？

        return netbiosDomainName;
    }
