推荐答案

尝试以下操作:

Try the following :

DirectoryEntry directoryEntry = new DirectoryEntry("WinNT://" + Environment.MachineName);
string userNames="Users : ";
foreach (DirectoryEntry child in directoryEntry.Children)
{
   if (child.SchemaClassName == "User")
   {
       userNames += child.Name + Environment.NewLine ;
   }
}
MessageBox.Show(userNames);

如何获取Active Directory组中的所有用户

公共静态数据集GetUsersForGroup(字符串GroupName)
{
DataSet dsUser =新的DataSet();
DirectoryEntry de = GetDirectoryObject();

//为可怕的搜索者创建实例
DirectorySearcher deSearch = new DirectorySearcher();

//设置搜索过滤器
deSearch.SearchRoot = de;
//deSearch.PropertiesToLoad.Add("cn);
deSearch.Filter =(&(objectClass = group)(cn =" + GroupName +))";

//获取分组结果
SearchResult results = deSearch.FindOne();

//在数据集中创建一个新的表对象
DataTable tbUser = dsUser.Tables.Add("Users");
tbUser.Columns.Add("UserName");
tbUser.Columns.Add("DisplayName");
tbUser.Columns.Add("EMailAddress");

//创建默认行
DataRow rwDefaultUser = tbUser.NewRow();
rwDefaultUser ["UserName"] ="0";
rwDefaultUser ["DisplayName"] =(未指定)";
rwDefaultUser ["EMailAddress"] =(未指定)";
tbUser.Rows.Add(rwDefaultUser);

//如果该组有效，则继续，否则返回空白数据集
if(结果！=空)
{
//创建指向组对象的链接，这样我们就可以获取成员列表
//在组内
DirectoryEntry deGroup =新的DirectoryEntry(results.Path，ADAdminUser，ADAdminPassword，AuthenticationTypes.Secure);
//分配属性集合
System.DirectoryServices.PropertyCollection pcoll = deGroup.Properties;
int n = pcoll ["member"].Count;

//如果该组有成员，则获取详细信息并分配给表
for(int l = 0; l< n; l ++)
{
//创建指向用户对象的链接，可以获取FirstName，LastName和SUername
DirectoryEntry deUser =新DirectoryEntry(ADFullPath +"/" + pcoll ["member"] [l] .ToString()，ADAdminUser，ADAdminPassword，AuthenticationTypes.Secure);

//设置一个新的空行
DataRow rwUser = tbUser.NewRow();

//填充列
rwUser ["UserName"] = GetProperty(deUser，"cn");
rwUser ["DisplayName"] = GetProperty(deUser，"givenName")+" + GetProperty(deUser，"sn");
rwUser ["EMailAddress"] = GetProperty(deUser，"mail");
//将该行追加到数据集的表中
tbUser.Rows.Add(rwUser);

//关闭目录条目对象
deUser.Close();

}
de.Close();
deGroup.Close();
}

返回dsUser;
}

How to get all users in an Active Directory Group

public static DataSet GetUsersForGroup(string GroupName)
{
DataSet dsUser = new DataSet();
DirectoryEntry de = GetDirectoryObject();

//create instance fo the direcory searcher
DirectorySearcher deSearch = new DirectorySearcher();

//set the search filter
deSearch.SearchRoot =de;
//deSearch.PropertiesToLoad.Add("cn");
deSearch.Filter = "(&(objectClass=group)(cn=" + GroupName +"))";

//get the group result
SearchResult results= deSearch.FindOne();

//Create a new table object within the dataset
DataTable tbUser = dsUser.Tables.Add("Users");
tbUser.Columns.Add("UserName");
tbUser.Columns.Add("DisplayName");
tbUser.Columns.Add("EMailAddress");

//Create default row
DataRow rwDefaultUser = tbUser.NewRow();
rwDefaultUser ["UserName"]= "0";
rwDefaultUser ["DisplayName"]="(Not Specified)";
rwDefaultUser ["EMailAddress"]="(Not Specified)";
tbUser.Rows.Add(rwDefaultUser);

//if the group is valid, then continue, otherwise return a blank dataset
if(results !=null)
{
//create a link to the group object, so we can get the list of members
//within the group
DirectoryEntry deGroup= new DirectoryEntry(results.Path,ADAdminUser,ADAdminPassword,AuthenticationTypes.Secure);
//assign a property collection
System.DirectoryServices.PropertyCollection pcoll = deGroup.Properties;
int n = pcoll["member"].Count;

//if there are members fo the group, then get the details and assign to the table
for (int l = 0; l < n ; l++)
{
//create a link to the user object sot hat the FirstName, LastName and SUername can be gotten
DirectoryEntry deUser= new DirectoryEntry(ADFullPath + "/" +pcoll["member"][l].ToString(),ADAdminUser,ADAdminPassword,AuthenticationTypes.Secure);

//set a new empty row
DataRow rwUser = tbUser.NewRow();

//populate the column
rwUser["UserName"]= GetProperty(deUser,"cn");
rwUser["DisplayName"]= GetProperty(deUser,"givenName") + " " + GetProperty(deUser,"sn");
rwUser["EMailAddress"]= GetProperty(deUser,"mail");
//append the row to the table of the dataset
tbUser.Rows.Add(rwUser);

//close the directory entry object
deUser.Close();

}
de.Close();
deGroup.Close();
}

return dsUser;
}
