但是DirectorySearcher仅具有1000个限制?

But DirectorySearcher has only 1000 limit ??

推荐答案

没有看到您的代码，我不知道为什么您看到msExchRecipientDisplayType属性的System.__ComObject值.

Without seeing your code, I don't know why you're seeing a System.__ComObject value for the msExchRecipientDisplayType attribute.

关于1000个结果的限制:这是Active Directory的限制，而不仅仅是DirectorySearcher.为了获得更多结果，您需要启用分页，这可以通过设置DirectorySearcher的="nofollow noreferrer"> PageSize 属性.只需将其设置为1000，它将继续为接下来的一千个查询，直到没有其他查询为止.例如，

About the 1000 result limit: this is a limit from Active Directory, not just DirectorySearcher. To get more results, you need to enable paging, which you can do by setting the PageSize property of the DirectorySearcher. Just set it to 1000 and it will keep making new queries for the next thousand until there are no more. For example,

var ds = new DirectorySearcher() {
    Filter = "(&(objectClass=user)(objectCategory=person))",
    PropertiesToLoad = { "msExchRecipientDisplayType" },
    PageSize = 1000
};
