Question

我有一个查询，它正在向AD发送并抓取所有电子邮件。我的问题是，查询需要花费很长时间才能执行（通过var whatEverString = "My test String"; var pattern = /^my/i var result = pattern.test(whatEverString); if (result === true) { console.log(pattern, "pattern did match !"); } else { console.log(pattern, " pattern did NOT match"); } 15-20秒）来提取大约3,000个电子邮件地址。我正在考虑在AJAX中存储结果集（在列表中）。我将列表放入下拉列表中以填充电子邮件。这是我的疑问：

memory cache

所以我的困境是，我正试图找到一种方法来加快下载列表的下载过程。实现这一目标的最佳方法是什么？内存缓存？我愿意接受你认为合理的任何选择......

https://msdn.microsoft.com/en-us/library/94xkskdf.aspx将其存储在应用程序中。每次回收应用程序池时都会清理它，并在其余时间保持不变。这个工作没什么特别的。

[WebMethod]
public static List<EmailDetails> GetEmails()
{
    if(HttpContext.Current.Application["sortedEmailAddresses"]==null) {

        List<EmailDetails> emailAddresses = new List<EmailDetails>();

        //queries AD to pull all users
        var search = new DirectorySearcher();
        search.Filter = "(&(objectClass=user)(mail=*)(displayName=*))";
        search.PageSize = 1000;

        using (var results = search.FindAll())
        {
            foreach (SearchResult result in results)
            {
                emailAddresses.Add(new EmailDetails
                {
                    EmailAddress = result.Properties["mail"][0].ToString(),
                    EmailDisplayName = result.Properties["displayName"][0].ToString()
                });
            }
        }

        //sort email address list alphabetically and return sorted list
        List<EmailDetails> sortedEmailAddresses = emailAddresses.OrderBy(o => o.EmailDisplayName).ToList();
        HttpContext.Current.Application["sortedEmailAddresses"] = sortedEmailAddresses;
    }
    return HttpContext.Current.Application["sortedEmailAddresses"] as List<EmailDetails>;
}

在缓存中存储查询结果
