What is the best way to get all the individual email addresses comprising an exchange distribution list?

For eg: I have this distribution list called abc@domainname.com that has email addresses:

1. a@domainname.com
2. b@domainname.com
3. c@domainname.com

Now I need to get these addresses using C# code.

I found solution using LDAP but I felt it'd be a hassle to figure out LDAP path to my Active Directory.

// How do I get this LDAP Path, username and password?  
// Is the username and password service account credentials of the app?  
// And do they need to be registered in AD?  
var entry = new DirectoryEntry("LDAP Path");//, username, password);

UPDATE: For me, LDAP way only worked for finding email addresses inside AD groups, for eg: named ITSolutionDeliveryDevelopers group. NOT inside Exchange Distribution Lists, for eg: named abc@domainname.com.

// I was able to figure out entry as suggested by @Gabriel Luci and all of the following possible formats worked for me:
// ngroupnet.com is my company domain name.
var entry = new DirectoryEntry();
var entry = new DirectoryEntry("LDAP://ngroupnet.com");
var entry = new DirectoryEntry("LDAP://ngroupnet.com", "MyAccountUsername", "MyAccountPassword");
var entry = new DirectoryEntry("LDAP://ngroupnet.com", "MyName@mycompany.com", "MyEmailAccountPassword");

LDAP Way:

public static List<string> GetDistributionListMembers(string dlName = "abc@domainname.com")
{
    var result = new List<string>();
    try
    {
        // How do I get this LDAP Path?
        var entry = new DirectoryEntry("LDAP Path");//, username, password);
        var search = new DirectorySearcher(entry);
        search.Filter = $"CN={dlName}";
        int i = search.Filter.Length;

        string str = "", str1 = "";
        foreach (SearchResult AdObj in search.FindAll())
        {
            foreach (String objName in AdObj.GetDirectoryEntry().Properties["member"])
            {
                str += Convert.ToString(objName) + "&lt;Br>";
                int selIndex = objName.IndexOf("CN=") + 3;
                int selEnd = objName.IndexOf(",OU") - 3;
                str1 += objName.Substring(selIndex, selEnd).Replace("\\", "");

                DirectorySearcher dsSearch = new DirectorySearcher(entry);
                dsSearch.Filter = "CN=" + objName.Substring(selIndex, selEnd).Replace("\\", "");
                foreach (SearchResult rs in dsSearch.FindAll())
                {
                    //str1 += "&lt;p align='right'><font face='calibri' color='#2266aa' size=2>" + Convert.ToString(rs.GetDirectoryEntry().Properties["mail"].Value) + "|" + Convert.ToString(rs.GetDirectoryEntry().Properties["displayName"].Value) + "|" + Convert.ToString(rs.GetDirectoryEntry().Properties["sAMAccountName"].Value) + "|" + Convert.ToString(rs.GetDirectoryEntry().Properties["department"].Value) + "|" + Convert.ToString(rs.GetDirectoryEntry().Properties["memberOf"].Value) + "&lt;/font></p>";
                    str1 = Convert.ToString(rs.GetDirectoryEntry().Properties["mail"].Value);
                    result.Add(str1);
                }
            }

        }
        return result;
    }
    catch (Exception ex)
    {
        //Do some logging or what have you.
        throw;
    }
}

So I just went with the EWS route.

EWS Way:

public static static List<string> GetDistributionListMembers(string dlName = "abc@domainname.com")
{
    try
    {
        var service = new ExchangeService();
        var cred = new WebCredentials("sharedmailbox@domain.com", "some_password");
        service.Credentials = cred;
        service.Url = new Uri("https://outlook.office365.com/ews/exchange.asmx");
        service.TraceEnabled = true;
        service.TraceFlags = TraceFlags.All;

        var expandedEmailAddresses = new List<string>();

        ExpandGroupResults myGroupMembers = service.ExpandGroup(dlName);

        foreach (EmailAddress address in myGroupMembers.Members)
        {
            expandedEmailAddresses.Add(address.Address);
        }

       return expandedEmailAddresses;
    }
    catch (Exception ex)
    {
        // The DL doesn't have any members. Handle it how you want.
        // Handle/ Log other errors.
    }
}

Is EWS approach a good way?

If Yes, then I'm good. If not, I'll have to figure out that LDAP path.

Or if there's even a better way, please let me know.
