如何从Active Directory获取用户的电子邮件地址？

Question

我试图在AD中获取用户的电子邮件地址但没有成功.

String account = userAccount.Replace(@"Domain\", "");
DirectoryEntry entry = new DirectoryEntry();

try {
    DirectorySearcher search = new DirectorySearcher(entry);

    search.PropertiesToLoad.Add("mail");  // e-mail addressead

    SearchResult result = search.FindOne();
    if (result != null) {
        return result.Properties["mail"][0].ToString();
    } else {
        return "Unknown User";
    }
} catch (Exception ex) {
    return ex.Message;
}

任何人都可以看到问题或指向正确的方向吗？

Answer 1

我已成功使用此代码(其中"account"是没有域(domain\account)的用户登录名:

// get a DirectorySearcher object
DirectorySearcher search = new DirectorySearcher(entry);

// specify the search filter
search.Filter = "(&(objectClass=user)(anr=" + account + "))";

// specify which property values to return in the search
search.PropertiesToLoad.Add("givenName");   // first name
search.PropertiesToLoad.Add("sn");          // last name
search.PropertiesToLoad.Add("mail");        // smtp mail address

// perform the search
SearchResult result = search.FindOne();

你们太努力了：

// Look up the current user's email address
string eMail =  UserPrincipal.Current.EmailAddress;
