昏暗的DS作为新DirectorySearcher从
code设置DirectorySearcher从

使用GetDirectoryEntry当你想   看现场条目，而不是   通过返回的条目   DirectorySearcher从，或当你想   调用，这是该对象的方法   回来了。

     

请注意：   调用GetDirectoryEntry每个SearchResult中通过DirectorySearcher从恢复可能会很慢。

When using the FindAll() method of the DirectorySearcher in .net, does the GetDirectoryEntry() method of the SearchResultCollection require another trip to Active Directory? e.g....

Dim src As SearchResultCollection
Dim ds As New DirectorySearcher
' code to setup DirectorySearcher


' go to Active Directory and fill collection with results
src = ds.FindAll()

'...later on in code or whatever
' does the next line of code require another trip to Active Directory?
Dim de As DirectoryEntry = src.item(0).GetDirectoryEntry()

解决方案

According to the documentation it will requery AD to get the directory entry.

Reference

Use GetDirectoryEntry when you want to look at the live entry instead of the entry that was returned through DirectorySearcher, or when you want to invoke a method on the object that was returned.

Note: Calling GetDirectoryEntry on each SearchResult returned through DirectorySearcher can be slow.
