I cannot access the description of a group like this:
$web = Get-SPWeb "http.//yourUrl"
$web.SiteGroups | %{write-host $_.Name, $_.Description}
According to this, the description value is in fact stored as "About Me" in the DB-table AllUserData.
Using the group web service and $SPService.GetGroupCollectionFromWeb() also retreives groups without description.
How to read the description property of an SPGroup?
This holds everything to get the group's description. You need this object:
$text = $web.SiteUserInfoList.Fields[($web.SiteUserInfoList.Fields | ?{$_.InternalName -eq "Notes"})]
You fetch the group item based on id and extract the description with the internal name
$groupItem = $web.SiteUserInfoList.GetItemById($_.Id)
$description = $groupItem[$text.InternalName]
The non-pedagogic version of accessing the description field does not deal with my $text variable, and uses this:
$description = $groupItem["Notes"]
If you are about to display this data you should be aware that this is HTML
Please try the below code, It displays all the group's description.
$web = Get-SPWeb "your site URL"
$groups=$web.SiteGroups
foreach($group in $groups)
{
write-host $group.Description
}
As the same that you have to do by C#. Basically exist a list where SharePoint save this information. Basically this list is the SiteUserInfoList has @StefG wrote.
There are many fancy thing about this list. For more information take a look here: http://salvatoredifaziosharepoint.blogspot.co.uk/2013/08/how-to-retrieve-spgroup-description.html
