AD账号信息

 private const string domainName = "ms.com";
private const string adAdmin = "administrator";
private const string password = "pass@word1";
private const string ouName = "XX有限公司";

private DataTable GetADUsers()
{
DataTable dt = new DataTable();
dt.Columns.Add("sAMAccountName");//账号
dt.Columns.Add("Name");//姓名
dt.Columns.Add("mail"); //邮箱地址
dt.Columns.Add("OU"); //用户组织

DirectoryEntry adRoot = new DirectoryEntry("LDAP://" + domainName, adAdmin, password, AuthenticationTypes.Secure);
DirectoryEntry ou = adRoot.Children.Find("OU=" + ouName);

DirectorySearcher mySearcher = new DirectorySearcher(ou);
mySearcher.Filter = ("(objectClass=user)"); //user表示用户，group表示组

foreach (System.DirectoryServices.SearchResult resEnt in mySearcher.FindAll())
{
DataRow dr = dt.NewRow();
dr["sAMAccountName"] = string.Empty;
dr["Name"] = string.Empty;
dr["mail"] = string.Empty;
dr["OU"] = string.Empty;

DirectoryEntry user = resEnt.GetDirectoryEntry();
if (user.Properties.Contains("sAMAccountName"))
{
dr["sAMAccountName"] = user.Properties["sAMAccountName"][0].ToString();
}
if (user.Properties.Contains("Name"))
{
dr["Name"] = user.Properties["Name"][0].ToString();
}
if (user.Properties.Contains("mail"))
{
dr["mail"] = user.Properties["mail"][0].ToString();
}
if (user.Parent.Name != string.Empty && user.Parent.Name.IndexOf('=') > -1)
{
//获取用户所在的组织单位
dr["OU"] = user.Parent.Name.Split('=')[1];
}
dt.Rows.Add(dr);
}
return dt;
}
}

如果想要知道用户信息中都包含哪些字段,可以foreach出来看看

DirectoryEntry user = resEnt.GetDirectoryEntry();
foreach (string property in user.Properties.PropertyNames)
{
Console.WriteLine("字段名: " + property);
}

private DataTable GetADUsersAllProperty()
{
Boolean done = true;
DataTable dt = new DataTable();
DirectoryEntry adRoot = new DirectoryEntry("LDAP://" + domainName);

DirectorySearcher mySearcher = new DirectorySearcher(adRoot);
mySearcher.Filter = ("(objectClass=user)"); //user表示用户，group表示组

foreach (System.DirectoryServices.SearchResult resEnt in mySearcher.FindAll())
{
DirectoryEntry user = resEnt.GetDirectoryEntry();
if (done)
{
foreach (string property in user.Properties.PropertyNames)
{
dt.Columns.Add(property);
}
done = false;
}

DataRow dr = dt.NewRow();
for (int i = 0; i < dt.Columns.Count; i++)
{
if (user.Properties.Contains(dt.Columns[i].ColumnName))
{
dr[i] = user.Properties[dt.Columns[i].ColumnName][0].ToString();
}else dr[i] = string.Empty;
}
dt.Rows.Add(dr);
}
return dt;
}
