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; }
