c# active directory ldap

Aşağıda C# ile Active Directory üzerinde nasıl sorgu yapıldığına dair bir örnek var.

Bu örnek üzerinden gidebilirsiniz. 

Kodlardaki username ve password'u kendinize göre düzenleyin. Buradaki user yani kullanıcı Administrator haklarına sahip olmalıdır.

 DirectoryEntry rootDSE = rootDSE = new DirectoryEntry("LDAP://OU="",OU=" ",dc="me",dc=com", username, password);

    DirectorySearcher search = new DirectorySearcher(rootDSE);

    search.PageSize = 1001;// To Pull up more than 100 records.

     search.Filter = "(&(objectClass=user)(!userAccountControl:1.2.840.113556.1.4.803:=2))";//UserAccountControl will only Include Non-Disabled Users.
      SearchResultCollection result = search.FindAll();

         foreach (SearchResult item in result)
        {
            if (item.Properties["cn"].Count > 0)
            {
                DisplayName = item.Properties["cn"][0].ToString();
            }
            if (item.Properties["mail"].Count > 0)
            {
                EmailAddress = item.Properties["mail"][0].ToString();
            }
            if (item.Properties["SamAccountName"].Count > 0)
            {
                DomainName = item.Properties["SamAccountName"][0].ToString();
            }
            if (item.Properties["department"].Count > 0)
            {
                Department = item.Properties["department"][0].ToString();
            }
            if (item.Properties["title"].Count > 0)
            {
                title = item.Properties["title"][0].ToString();
            }
            if (item.Properties["company"].Count > 0)
            {
                company = item.Properties["company"][0].ToString();
            }
            if (item.Properties["DistinguishedName"].Count > 0)
            {
                memberof = item.Properties["DistinguishedName"][0].ToString();
            }
            if (item.Properties["AccountExpirationDate"].Count > 0)
            {
                string aaa = item.Properties["AccountExpirationDate"][0].ToString();
            }

              dt.Rows.Add(DisplayName, EmailAddress, DomainName, Department, title, company, memberof);
             DisplayName = string.Empty;
             EmailAddress = string.Empty;
             DomainName = string.Empty;
             Department = string.Empty;
             title = string.Empty;
             company = string.Empty;
             memberof = string.Empty;

               rootDSE.Dispose();
