You need to set DirectorySearcher.PageSize to a non-zero value to get all results.

BTW you should also dispose DirectorySearcher when you're finished with it

<pre><code>using(var srch = new DirectorySearcher(dirEnt, "(objectClass=Group)", loadProps))
{
 srch.PageSize = 1000;
 var results = srch.FindAll();
}
</code></pre>

The API documentation isn't very clear, but essentially:

<ul>
<li>when you do a paged search, the SizeLimit is ignored, and all matching results are returned as you iterate through the results returned by FindAll. Results will be retrieved from the server a page at a time. I chose the value of 1000 above, but you can use a smaller value if preferred. The tradeoff is: using a small PageSize will return each page of results faster, but will require more frequent calls to the server when iterating over a large number of results.</li>
<li>by default the search isn't paged (PageSize = 0). In this case up to SizeLimit results is returned.</li>
</ul>

As Biri pointed out, it's important to dispose the SearchResultCollection returned by FindAll, otherwise you may have a memory leak <a href="https://docs.microsoft.com/en-us/dotnet/api/system.directoryservices.directorysearcher.findall#remarks" rel="noreferrer">as described in the Remarks section of the MSDN documentation for DirectorySearcher.FindAll</a>.

One way to help avoid this in .NET 2.0 or later is to write a wrapper method that automatically disposes the SearchResultCollection. This might look something like the following (or could be an extension method in .NET 3.5):

<pre><code>public IEnumerable&lt;SearchResult&gt; SafeFindAll(DirectorySearcher searcher)
{
 using(SearchResultCollection results = searcher.FindAll())
 {
 foreach (SearchResult result in results)
 {
 yield return result; 
 } 
 } // SearchResultCollection will be disposed here
}
</code></pre>

You could then use this as follows:

<pre><code>using(var srch = new DirectorySearcher(dirEnt, "(objectClass=Group)", loadProps))
{
 srch.PageSize = 1000;
 var results = SafeFindAll(srch);
}
</code></pre>

I tried to use given solution to achieve pagination but it doesnt work.
I set pageSize = 100; and i get all the items through searchResult.
dirSearcher = new DirectorySearcher(direntry);
dirSearcher.Filter = (&quot;(|(objectClass=volume). (objectClass=user)(objectClass=printQueue)(objectClass=computer). (objectClass=organizationalUnit)(objectClass=Group))&quot;);
<pre><code> dirSearcher.PageSize = 100;
 dirSearcher.SearchScope = System.DirectoryServices.SearchScope.Subtree;
 dirSearcher.ServerTimeLimit = new TimeSpan(1000);

 //dirSearcher.VirtualListView = new DirectoryVirtualListView(0, 100, 1);


 using (SearchResultCollection results = dirSearcher.FindAll())
 {
 foreach (SearchResult result in results)
 {
 DirectoryEntry ent = result.GetDirectoryEntry();
 ADItem ProviderItem = Context.ConvertToItem(ent, true);

 if (ProviderItem != null)
 {
 ProviderItem.IsPartialData = true;
 ProviderItems.Add(ProviderItem);
 }
 }

 }
 }
</code></pre>

I just noticed that the return list for results is limited to 1000. I have more than 1000 groups in my domain (HUGE domain). How can I get more than 1000 records? Can I start at a later record? Can I cut it up into multiple searches?

Here is my query:

<pre><code>DirectoryEntry dirEnt = new DirectoryEntry("LDAP://dhuba1kwtn004");
string[] loadProps = new string[] { "cn", "samaccountname", "name", "distinguishedname" };
DirectorySearcher srch = new DirectorySearcher(dirEnt, "(objectClass=Group)", loadProps);
var results = srch.FindAll();
</code></pre>

I have tried to set srch.SizeLimit = 2000;, but that doesn't seem to work. Any ideas?

Can I get more than 1000 records from a DirectorySearcher?

服务器

我刚刚注意到结果的返回列表被限制为1000个。我在我的域(巨大的域)中有1000多个组。怎样才能得到1000条以上的记录？我可以从以后的记录开始吗？我能把它分成多个搜索吗？下面是我的问题：DirectoryEntry dirEnt = new DirectoryEntry("LDAP://dhuba1kwtn004")...

问我可以从DirectorySearcher中获得1000条以上的记录吗？
