我有以下代码需要用户名和密码,然后在计算机上创建用户并将其添加到两个特定组。当我到达组合部分时,它非常慢,我不知道为什么。根据我的日志文件,我最后一次运行说,将用户添加到用户组需要7分钟,但IIS_IUSRS速度非常快。添加到组时,在本地计算机上创建用户非常缓慢
下面是我最初的代码,它调用了做真正工作的方法。我尝试过使用任务来帮助加快检查组的过程,但它仍然运行速度超慢。
public void Apply(Section.User.User user, Action<string> status)
{
#region Sanity Checks
if (user == null)
{
throw new ArgumentNullException("user");
}
if (status == null)
{
throw new ArgumentNullException("status");
}
#endregion
_logger.Debug(string.Format("Starting to apply the user with name {0}", user.UserName));
status(string.Format("Applying User {0} to the system.", user.UserName));
using (PrincipalContext pc = new PrincipalContext(ContextType.Machine))
{
UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(pc, user.UserName);
try
{
_logger.Debug("Checking if user already exists");
if (userPrincipal == null)
{
userPrincipal = CreateNewUser(user, pc);
}
_logger.Debug("Setting user password and applying to the system.");
userPrincipal.SetPassword(user.UserPassword);
userPrincipal.Save();
Task<PrincipalSearchResult<Principal>> groups =
Task<PrincipalSearchResult<Principal>>.Factory.StartNew(userPrincipal.GetGroups);
_logger.Debug("Adding user to the groups.");
AddUserToGroups(pc, userPrincipal, groups, user.UserType.Equals(UserType.WorkerProcess.ToString()) ? "Administrators" : "Users", "IIS_IUSRS");
AddCurrentUser(user);
}
finally
{
if (userPrincipal != null)
{
userPrincipal.Dispose();
}
}
}
}
这是我用来创建用户的私有方法,如果它不存在。
private UserPrincipal CreateNewUser(Section.User.User user, PrincipalContext principal)
{
_logger.Debug("User did not exist creating now.");
UserPrincipal newUser = new UserPrincipal(principal)
{
Name = user.UserName,
Description = user.UserDescription,
UserCannotChangePassword = false,
PasswordNeverExpires = true,
PasswordNotRequired = false
};
_logger.Debug("User created.");
return newUser;
}
下面是组的逻辑。我在每次使用调试器时遇到的有问题的代码上面发表了一段评论。此外,调试日志条目始终是我在挂起之前获得的最后一个条目。
private void AddUserToGroups(PrincipalContext principal, UserPrincipal user, Task<PrincipalSearchResult<Principal>> userGroups, params string[] groups)
{
groups.AsParallel().ForAll(s =>
{
using (GroupPrincipal gp = GroupPrincipal.FindByIdentity(principal, s))
{
_logger.Debug(string.Format("Checking if user is alread in the group."));
if (gp != null && !userGroups.Result.Contains(gp))
{
_logger.Debug(string.Format("The user was not a member of {0} adding them now.", gp.Name));
//This is the point that the 7 minute hang starts
gp.Members.Add(user);
gp.Save();
_logger.Debug(string.Format("User added to {0}.", gp.Name));
}
}
});
}
任何帮助,这将不胜感激,因为这项目预计10月发布,但我不能释放与创建用户时7分钟挂起。
我不知道这是你的问题,但PrincipalContext不是[线程安全](http://msdn.microsoft.com/en-us/library/system.directoryservices.accountmanagement.principalcontext.aspx#threadSafetyToggle) 。您使用相同的PrincipalContext同时阅读和书写,这可能是您的问题。 –
当您删除'AsParellel().ForAll'时,执行速度会慢吗? –
在它说“用户不是{0}的成员现在添加它们之前或之后挂起。” –
