1、WindowsAccountHelper类实现

using System;using System.Collections.Generic;using System.DirectoryServices.AccountManagement;using System.Linq;public class WindowsAccountHelper{public static string LastErrorMsg { get; private set; }public static List<string> GetGroups(){var groups = new List<string>();try{var context = new PrincipalContext(ContextType.Machine);var queryGroup = new GroupPrincipal(context);var searcher = new PrincipalSearcher(queryGroup);searcher.FindAll().ToList().ForEach(t => groups.Add(t.Name));}catch (Exception){groups.Clear();}return groups;}public static List<string> GetGroupUsers(string groupName){var group = GetGroup(groupName);return GetGroupUsers(group);}public static List<string> GetGroupUsers(GroupPrincipal group){var users = new List<string>();if (group == null){return users;}group.GetMembers().ToList().ForEach(t => users.Add(t.Name));return users;}public static GroupPrincipal GetGroup(string groupName){GroupPrincipal group = null;try{var context = new PrincipalContext(ContextType.Machine);var queryGroup = new GroupPrincipal(context);var searcher = new PrincipalSearcher(queryGroup);foreach (var principal in searcher.FindAll()){var groupPrincipal = (GroupPrincipal)principal;if (groupPrincipal != null && groupPrincipal.Name.Equals(groupName)){group = groupPrincipal;break;}}}catch (Exception){// ignored}return group;}public static GroupPrincipal CreateGroup(string groupName, string description, bool isSecurityGroup){GroupPrincipal group;try{group = GetGroup(groupName);if (group == null){var context = new PrincipalContext(ContextType.Machine);group = new GroupPrincipal(context){Name = groupName,Description = description,IsSecurityGroup = isSecurityGroup,GroupScope = GroupScope.Local};group.Save();}}catch (Exception e){LastErrorMsg = e.Message;group = null;}return group;}public static bool DeleteGroup(string groupName){var group = GetGroup(groupName);if (group == null){return true;}var ret = true;try{group.Delete();}catch (Exception){ret = false;}return ret;}public static bool CreateWindowsAccount(string userName, string password,string displayName, string description, bool cannotChangePassword,bool passwordNeverExpires, string groupName){bool ret;try{var context = new PrincipalContext(ContextType.Machine);var group = GroupPrincipal.FindByIdentity(context, groupName);if (group == null){return false;}ret = CreateWindowsAccount(userName, password, displayName,description, cannotChangePassword, passwordNeverExpires, group);}catch (Exception){ret = false;}return ret;}public static bool CreateWindowsAccount(string userName, string password,string displayName, string description, bool cannotChangePassword,bool passwordNeverExpires, GroupPrincipal group){bool ret;try{if (group == null){return false;}var context = new PrincipalContext(ContextType.Machine);var user = UserPrincipal.FindByIdentity(context, userName)?? new UserPrincipal(context);user.SetPassword(password);user.DisplayName = displayName;user.Name = userName;user.Description = description;user.UserCannotChangePassword = cannotChangePassword;user.PasswordNeverExpires = passwordNeverExpires;user.Save();group.Members.Add(user);group.Save();ret = true;}catch (Exception){ret = false;}return ret;}public static bool DeleteWindowsAccount(List<string> userNameList){var ret = true;try{foreach (var userName in userNameList){var context = new PrincipalContext(ContextType.Machine);var user = UserPrincipal.FindByIdentity(context, userName);user?.Delete();}}catch (Exception){ret = false;}return ret;}public static bool ChangeUserGroup(string userName, string groupName){bool ret;try{var context = new PrincipalContext(ContextType.Machine);var group = GroupPrincipal.FindByIdentity(context, groupName);if (group == null){return false;}ret = ChangeUserGroup(userName, group);}catch (Exception){ret = false;}return ret;}public static bool ChangeUserGroup(string userName, GroupPrincipal group){bool ret;try{if (group == null){return false;}var context = new PrincipalContext(ContextType.Machine);var user = UserPrincipal.FindByIdentity(context, userName);if (user == null){return false;}if (!group.Members.Contains(user)){group.Members.Add(user);group.Save();}ret = true;}catch (Exception){ret = false;}return ret;}public static int UpdateGroupUsers(string groupName, List<string> userNames, string password = ""){var group = CreateGroup(groupName, string.Empty, false);if (group == null){return 0;}var userNameList = new List<string>();userNameList.AddRange(userNames);var addedUsers = new List<string>();int groupUserCount;try{foreach (var principal in group.GetMembers()){var user = (UserPrincipal)principal;if (user == null){continue;}if (userNameList.Contains(user.Name)){//已有用户addedUsers.Add(user.Name);}else{user.Delete();}}//已有用户数groupUserCount = addedUsers.Count;//剩余的即为需要添加的用户集合foreach (var userName in addedUsers){userNameList.Remove(userName);}//创建用户foreach (var userName in userNameList){if (CreateWindowsAccount(userName, password,userName, string.Empty,false, false, group)){groupUserCount++;}}}catch (UnauthorizedAccessException){groupUserCount = 0;}return groupUserCount;}}

2、使用示例

private bool CreateGroupUsers(string groupName, List<string> windowsUserList,string password, int userCount){var group = WindowsAccountHelper.CreateGroup(groupName, string.Empty, true);if (group == null){return false;}var userNames = WindowsAccountHelper.GetGroupUsers(group);foreach (var userName in WindowsUserList){if (!userNames.Contains(userName)){if (!WindowsAccountHelper.CreateWindowsAccount(userName, password,userName, string.Empty,false, false, group)){return false;}}}return true;}

以上就是使用C#实现Windows组和用户管理的示例代码的详细内容，更多关于C#实现Windows组和用户管理的资料请关注其它相关文章！
