Is there a hidden limit in SPSocialFeed.Threads?

Question

I tried to write a little application to get some kinds of extended Analytics.

I could get some very interesting numbers about Usage, Search terms, Used Memory etc. But while trying to access all Threads in the Newsfeed of a Teamsite I found a little barrier. When you try to find out how many posts do exist in one SiteCollection you can do that via:

var feedOption = new SPSocialFeedOptions
                        {
                            SortOrder = SPSocialFeedSortOrder.ByCreatedTime,
                            MaxThreadCount = 2000
                        };
var feeds = feedManager.GetFeedFor($"{mySite.Url}/newsfeed.aspx", feedOption);

But when you count the number of Threads in the feed:

feeds.Threads.Length

You will get a maximum of 100 Threads. It seems to be irrelevant what value you set for "MaxThreadCount", you only get Thread 0-99 (also tried using int.MaxValue).

Even if the MicroFeed list in that SiteCollection has 300 Posts, I can`t get the correct number of posts with the feedManager.

I couldn`t find any hint about this limitation in the MSDN description of the SPSocialFeed class or the Threads.

Is there another way to get the number of all existing Threads in a site newsfeed?

Answer 1

It's normal behavior, 2000 is invalid value for The SPSocialFeedOptions.MaxThreadCount

• The Valid values are between zero and 100.
• The default number of threads returned is 20.
• Setting the value to zero will set the MaxThreadCount property to the default value of 20.

The SPSocialFeedOptions.MaxThreadCount limitations is mentioned at this MSDN documntation SPSocialFeedOptions.MaxThreadCount

Answer 2

Wow. I found the reason for my problems. As M.Qassas wrote, there IS a limit to the int value of the property MaxThreadCount.

I couldn`t find it in the article https://msdn.microsoft.com/de-de/library/microsoft.office.server.social.spsocialfeedoptions.maxthreadcount.aspx , even if I set the page language to English.

But if you open the same article with the link from Qassas https://msdn.microsoft.com/en-us/library/microsoft.office.server.social.spsocialfeedoptions.maxthreadcount.aspx

You can clearly see another portion of text, telling me "Gets or sets the maximum number of threads to retrieve. Valid values are between zero and 100"

Really ?
