解决方法
这应该可以找到每个用户密码到期之前的剩余时间：
private static TimeSpan GetTimeRemainingUntilPasswordExpiration(string domain,string userName)
{
using (var userEntry = new System.DirectoryServices.DirectoryEntry(string.Format("WinNT://{0}/{1},user",domain,userName)))
{
var maxPasswordAge = (int)userEntry.Properties.Cast<System.DirectoryServices.PropertyValueCollection>().First(p => p.PropertyName == "MaxPasswordAge").Value;
var passwordAge = (int)userEntry.Properties.Cast<System.DirectoryServices.PropertyValueCollection>().First(p => p.PropertyName == "PasswordAge").Value;
return TimeSpan.FromSeconds(maxPasswordAge) - TimeSpan.FromSeconds(passwordAge);
}
}
注意：您需要添加对System.DirectoryServices的引用.
