如何从 Active Directory 获取用户的电子邮件地址?

问题描述

我试图在 AD 中获取用户的电子邮件地址，但没有成功.

I am trying to get a user's email address in AD without success.

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;
}

有人能看到问题或指出正确的方向吗?

Can anyone see the issue or point in the right direction?

推荐答案

免责声明:此代码不搜索 单个完全匹配，所以对于 domainj_doe 它可能会返回domainj_doe_from_external_department 的电子邮件地址(如果也存在类似名称的帐户).如果此类行为不受欢迎，则使用 samAccountName 过滤器而不是 anr 下面使用或过滤结果 另外.

Disclaimer: This code doesn't search for a single exact match, so for domainj_doe it may return domainj_doe_from_external_department's email address if such similarly named account also exists. If such behaviour is undesirable, then either use a samAccountName filter intead of an anr one used below or filter the results additionally.

我已成功使用此代码(其中帐户"是不带域的用户登录名(域帐户):

I have used this code successfully (where "account" is the user logon name without the domain (domainaccount):

// 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();
