Puis-je obtenir le service utilisateur à partir d'Active Directory en utilisant PrincipalContext()

Question

J'essaie d'obtenir le département de l'utilisateur à partir d'Active Directory. J'ai la classe suivante:

public class DomainContext 
{ 
     public string DisplayName { get; set; } 
     public string Name { get; set; } 
     public string SamAccountName { get; set; } 
     public string DistinguishedName { get; set; } 
     public string UserPrincipalName { get; set; } 
     public string Department { get; set; } 
} 

Ensuite, en utilisant la méthode ci-dessous, je suis en mesure d'obtenir le nom d'utilisateur, le nom d'affichage, compte sam, etc ....

public override void getUserDepts(SPItemEventProperties properties) 
{ 
    base.ItemUpdating(properties); 

    string[] offices = new string[] { "OfficeA", "OfficeB", "OfficeC" }; 

    string ADServerName = "*****"; 
    string ADusername = "******"; 
    string ADpassword = "*****"; 

    using (var context = new PrincipalContext(ContextType.Domain, ADServerName, ADusername, ADpassword)) 
    using (var searcher = new PrincipalSearcher(new UserPrincipal(context))) 
    { 
     var searchResults = searcher.FindAll(); 

     foreach (Principal p in searchResults) 
     { 
      if (p.DistinguishedName.ToLower().Contains(offices[0].ToLower()) || p.DistinguishedName.ToLower().Contains(offices[1].ToLower()) || p.DistinguishedName.ToLower().Contains(offices[2].ToLower()))) 
      { 
       DomainContext dc = new DomainContext(); 
       dc.DisplayName = p.DisplayName; 
       dc.UserPrincipalName = p.UserPrincipalName; 
       dc.Name = p.Name; 
       dc.SamAccountName = p.SamAccountName; 
       dc.DistinguishedName = p.DistinguishedName; 
       // dc.Department = p. **CAN NOT GET THE DEPARTMENT NAME** 
      } 
     } 
    } 
} 

mais je ne peux pas pour trouver comment je peux obtenir le nom du département.

Vous pouvez accéder au service en vérifiant ses propriétés sous-jacentes dans son DirectoryEntry

var property = "department"; 
var directoryEntry = p.GetUnderlyingObject() as DirectoryEntry; 
if (directoryEntry.Properties.Contains(property)) { 
    dc.Department = directoryEntry.Properties[property].Value.ToString(); 
} 

Vous pourriez envisager de transformer ce qui précède dans une méthode d'extension pour réduire le code répété.

Je compilé une liste des propriétés de l'utilisateur dans une classe comme des constantes

public static class ADUserProperties 
{ 
    public const String OBJECTCLASS = "objectClass"; 

    public const String CONTAINERNAME = "cn"; 

    public const String LASTNAME = "sn"; 

    public const String COUNTRYNOTATION = "c"; 

    public const String CITY = "l"; 

    public const String STATE = "st"; 

    public const String TITLE = "title"; 

    public const String POSTALCODE = "postalCode"; 

    public const String PHYSICALDELIVERYOFFICENAME = "physicalDeliveryOfficeName"; 

    public const String FIRSTNAME = "givenName"; 

    public const String MIDDLENAME = "initials"; 

    public const String DISTINGUISHEDNAME = "distinguishedName"; 

    public const String INSTANCETYPE = "instanceType"; 

    public const String WHENCREATED = "whenCreated"; 

    public const String WHENCHANGED = "whenChanged"; 

    public const String DISPLAYNAME = "displayName"; 

    public const String USNCREATED = "uSNCreated"; 

    public const String MEMBEROF = "memberOf"; 

    public const String USNCHANGED = "uSNChanged"; 

    public const String COUNTRY = "co"; 

    public const String DEPARTMENT = "department"; 

    public const String COMPANY = "company"; 

    public const String PROXYADDRESSES = "proxyAddresses"; 

    public const String STREETADDRESS = "streetAddress"; 

    public const String DIRECTREPORTS = "directReports"; 

    public const String NAME = "name"; 

    public const String OBJECTGUID = "objectGUID"; 

    public const String USERACCOUNTCONTROL = "userAccountControl"; 

    public const String BADPWDCOUNT = "badPwdCount"; 

    public const String CODEPAGE = "codePage"; 

    public const String COUNTRYCODE = "countryCode"; 

    public const String BADPASSWORDTIME = "badPasswordTime"; 

    public const String LASTLOGOFF = "lastLogoff"; 

    public const String LASTLOGON = "lastLogon"; 

    public const String PWDLASTSET = "pwdLastSet"; 

    public const String PRIMARYGROUPID = "primaryGroupID"; 

    public const String OBJECTSID = "objectSid"; 

    public const String ADMINCOUNT = "adminCount"; 

    public const String ACCOUNTEXPIRES = "accountExpires"; 

    public const String LOGONCOUNT = "logonCount"; 

    public const String LOGINNAME = "sAMAccountName"; 

    public const String SAMACCOUNTTYPE = "sAMAccountType"; 

    public const String SHOWINADDRESSBOOK = "showInAddressBook"; 

    public const String LEGACYEXCHANGEDN = "legacyExchangeDN"; 

    public const String USERPRINCIPALNAME = "userPrincipalName"; 

    public const String EXTENSION = "ipPhone"; 

    public const String SERVICEPRINCIPALNAME = "servicePrincipalName"; 

    public const String OBJECTCATEGORY = "objectCategory"; 

    public const String DSCOREPROPAGATIONDATA = "dSCorePropagationData"; 

    public const String LASTLOGONTIMESTAMP = "lastLogonTimestamp"; 

    public const String EMAILADDRESS = "mail"; 

    public const String MANAGER = "manager"; 

    public const String MOBILE = "mobile"; 

    public const String PAGER = "pager"; 

    public const String FAX = "facsimileTelephoneNumber"; 

    public const String HOMEPHONE = "homePhone"; 

    public const String MSEXCHUSERACCOUNTCONTROL = "msExchUserAccountControl"; 

    public const String MDBUSEDEFAULTS = "mDBUseDefaults"; 

    public const String MSEXCHMAILBOXSECURITYDESCRIPTOR = "msExchMailboxSecurityDescriptor"; 

    public const String HOMEMDB = "homeMDB"; 

    public const String MSEXCHPOLICIESINCLUDED = "msExchPoliciesIncluded"; 

    public const String HOMEMTA = "homeMTA"; 

    public const String MSEXCHRECIPIENTTYPEDETAILS = "msExchRecipientTypeDetails"; 

    public const String MAILNICKNAME = "mailNickname"; 

    public const String MSEXCHHOMESERVERNAME = "msExchHomeServerName"; 

    public const String MSEXCHVERSION = "msExchVersion"; 

    public const String MSEXCHRECIPIENTDISPLAYTYPE = "msExchRecipientDisplayType"; 

    public const String MSEXCHMAILBOXGUID = "msExchMailboxGuid"; 

    public const String NTSECURITYDESCRIPTOR = "nTSecurityDescriptor"; 

} 

et créé une méthode d'extension pour y accéder

public static string GetProperty(this DirectoryEntry directoryEntry , string propertyName, int index = 0) { 
    if (directoryEntry.Properties.Contains(propertyName) && index > -1 && index < directoryEntry.Properties[propertyName].Count) { 
     return oDE.Properties[propertyName][index].ToString(); 
    } else { 
     return string.Empty; 
    } 
} 

public static string GetProperty(this Principal principal, string property) { 
    var directoryEntry = principal.GetUnderlyingObject() as DirectoryEntry; 
    return directoryEntry.GetProperty(property); 
} 

Cela permettrait alors votre code à être mis à jour

dc.Department = p.GetProperty(ADUserProperties.DEPARTMENT);
