无法使用c#.Active Directory查找属性TelephoneNumber [英] Not able to find the property telephoneNumber using c#.Active Directory

问题描述

大家好，

我无法从Active Directory中获取 telephoneNumber 属性值
DirectoryEntry条目=新的DirectoryEntry(" LDAP://CN = Users，DC = domain，DC = com ");
          DirectorySearcher Dsearch =新的DirectorySearcher(entry);
         字符串名称=用户";
          //Dsearch.Filter =(&(objectClass = user)(l =" +名称+))" ;;
          Dsearch.Filter =(&(objectCategory = User)(samaccountname =""+名称+")));
          //从活动目录中获取所有条目.
          //姓氏，名字，名字首字母，家庭邮寄地址，标题，公司等.
          SearchResult sResultSet = Dsearch.FindOne();

Im not able to get the telephoneNumber property value from the Active directory
DirectoryEntry entry = new DirectoryEntry("LDAP://CN=Users,DC=domain,DC=com");
           DirectorySearcher Dsearch = new DirectorySearcher(entry);
           string Name = "user";
           //Dsearch.Filter = "(&(objectClass=user)(l=" + Name + "))";
           Dsearch.Filter = "(&(objectCategory=User)(samaccountname=" + Name + "))";
           // get all entries from the active directory.
           // Last Name, name, initial, homepostaladdress, title, company etc..
           SearchResult sResultSet = Dsearch.FindOne();

sResultSet.Properties ["电话号码"] [0] .ToString();

sResultSet.Properties["telephoneNumber"][0].ToString() ;

我是否可以获取其他属性，是否需要Active Directory的任何权限才能获取电话号码.

Im able to get other properties , is it required any permissions from Active directory for getting the phone number.

Muqeem，

Hi Muqeem,

请参见以下示例代码:

Step 1: 

Add reference to System.DirectoryServices amd import it in the code by entering using System.DirectoryServices;

Step 2: 

We need the AD Location, AD Userid and AD Password in order to read data from it. 

We store these values in web.config: 
<appSettings>
<add key="GaadLocation" value="LDAP://XXXXX:XXX"/>
<add key="GaadUserName" value="XXXXXX"/>
<add key="GaadPassword" value="XXXXXX"/>
</appSettings>

Step 3:

In order to store the data fetched from AD, we created a class and defined some properties.

public class ADContact
{
public string UniqueId {get; set; }
public string LastName { get; set; }
public string DepartmentNumber { get; set; }
public string EmployeeType { get; set; }
public string TelephoneNumber { get; set; }
public string FirstName { get; set; }
public string UserStatus { get; set; }
public string Mail { get; set; }
public string Mobile { get; set; }
public string Title {get; set; }
}

Step 4: Create a method that will return a datatable so that we can iterate through the result.

public List GetADContacts(string SirName, string GivenName, string UniqueId)
{}

Step 5:

Within the method, create a SearchResultCollection object , a datatable, and list of AD properties to access:

SearchResultCollection results = null;
List GaadData = new List();

string ADLocation, ADUserId, ADUserPassword = string.Empty;
#region List of AD Properties
string[] properties = new string[]
{
"modifyTimestamp",
"uid",
"sn",
"departmentNumber",
"facsimileTelephoneNumber",
"givenName",
"mail"
};
#endregion

Step 6:
Declare a try-catch block and within try- write the following code:

try {

string strfilter = string.Empty;

//Get AD Settings from web.config
ADLocation = ConfigurationManager.AppSettings["ADLocation"];
ADUserId = ConfigurationManager.AppSettings["ADUserName"];
ADUserPassword = ConfigurationManager.AppSettings["ADPassword"];

//Create an instance of DirectoryEntry by passing the setting valies) 
DirectoryEntry root = new DirectoryEntry(ADLocation, ADUserId, ADUserPassword, AuthenticationTypes.FastBind);

//Create the filter string : we need to search the Ad for people matching the search criteria. Here we are passing three parameters: SirName, GivenName, Uid. If any field is blank, we are putting * there. that is to get all values

strfilter = String.Format(
"(&(&(sn={0})(givenname={1})(uid={2})))",
String.IsNullOrEmpty(SirName) ? "*" : SirName + "*",
String.IsNullOrEmpty(GivenName) ? "*" : GivenName + "*",
String.IsNullOrEmpty(UniqueId) ? "*" : UniqueId + "*");

if (strfilter != "")
{
DirectorySearcher searcher = new DirectorySearcher(root, strfilter, properties);
searcher.Asynchronous = true;
searcher.SearchScope = SearchScope.Subtree;
results = searcher.FindAll();
}
foreach (SearchResult result in results)
{
ADContact contact = new ADContact();

if (result.Properties["uid"].Count > 0)
contact.UniqueId= Convert.ToString(result.Properties["uid"][0]);

if (result.Properties["title"].Count > 0)
contact.Title = Convert.ToString(result.Properties["title"][0]);

if (result.Properties["sn"].Count > 0)
contact.LastName = Convert.ToString(result.Properties["sn"][0]);

if (result.Properties["givenName"].Count > 0)
contact.FirstName = Convert.ToString(result.Properties["givenName"][0]);

if (result.Properties["facsimileTelephoneNumber"].Count > 0)
contact.TelephoneNumber = Convert.ToString(result.Properties["facsimileTelephoneNumber"][0]);

if (result.Properties["mobile"].Count > 0)
contact.Mobile = Convert.ToString(result.Properties["mobile"][0]);

if (result.Properties["mail"].Count > 0)
contact.Mail = Convert.ToString(result.Properties["mail"][0]);

ADData.Add(contact);
}
return ADData;
}
catch (Exception ex)
{
throw ex;
}
