AD里的一些属性:"accountExpires", "pwdLastSet" 等,在ADSIEDIT.msc中查看类型为LargerInteger,但不能通过DirectoryEntry属性直接读出,读他人一篇blog得到解决方法。添加com引用using ActiveDs;使用ActiveDs里的类型,强制转化属性的value为IADsLargeInteger类型,在调用GetLongValue方法转为long型,下面代码拷贝自引用blog。
public
class
AdUser : AdItem
{ // http://msdn.microsoft.com/library/en-us/dnclinic/html/scripting09102002.asp public DateTime PasswordExpirationDate { get { if(IsPasswordNotExpire) { return DateTime.MaxValue; // 帐号被设置为密码永不过期 } else { long lastChanged; try { lastChanged = GetLongValue((IADsLargeInteger)Properties["pwdLastSet"][0]); } catch(Exception) { return DateTime.MinValue; // 密码没有被设置过 } IADsLargeInteger maxAge = (IADsLargeInteger)Server.Properties["maxPwdAge"][0]; if(maxAge.LowPart == 0) return DateTime.MaxValue; // 域中密码没有设置最大有效期限 else return PasswordLastChanged.AddDays(Server.MaxPasswordDays); } } } }
internal
long
GetLongValue(IADsLargeInteger value)
{ // 将 IADsLargeInteger 内容转换为 long 之前必须小心溢出 // http://www.rlmueller.net/Integer8Discussion.htm return (long)(((ulong)value.HighPart << 32) + (uint)value.LowPart); }
用户是否可以远程登录属性的读取方法:
引用名称空间:using TSUSEREXLib;
先将DirectoryEntry 变成基本的adsi类型,然后再定义为IADsTSUserEx类型,在调用里面的方法。
object objAD = userDEntry.NativeObject ;
int k = ((IADsTSUserEx)objAD).AllowLogon;
//Value that specifies whether to allow remote observation or remote control of the user's
//Terminal Services session. Values include: "Disable" (0), "EnableInputNotify" (1),
//"EnableInputNoNotify" (2), "EnableNoInputNotify" (3), and "EnableNoInputNoNotify" (4).
