BreakRoleInheritance(true) has no effect on Document Set Sub Folders

Question
I am trying to Break Inheritance on a sub folder within a Document Set using the following code. After running the code and examining the Document Set's Sub Folder I can see that it still inherits from the parent. Can anyone see what is wrong here?
using(var site = new SPSite("http://tmtech-sp13b:8080/sites/Doc%20Set%20Test")) {
// TODO: Replace with current site
using(var web = site.AllWebs[0]) {
SPList list = web.Lists["Projects"];
// Test if list has project document set content type
if (list.ContentTypes.Cast < SPContentType > ().Any(c => c.Parent.Id == _projContentTypeId)) {
foreach(SPFolder projfolder in list.RootFolder.SubFolders) {
if (projfolder.Name.ToLower() != "forms") {
Console.WriteLine(projfolder.Name);
// Container to hold the temporary files which are to be deleted.
List < SPFile > files2Delete = new List < SPFile > ();
foreach(SPFolder projSubFolder in projfolder.SubFolders) {
// Set Contractor Permissions
if (projSubFolder.Name == CONTRACTOR_FOLDER_NAME) {
SPRoleAssignment roleAssignment = new SPRoleAssignment((SPPrincipal) web.SiteGroups["Contractors"]);
SPFolder f = web.GetFolder(projSubFolder.Item.Url);
SPListItem i = f.Item;
i.BreakRoleInheritance(true);
roleAssignment.RoleDefinitionBindings.Add(web.RoleDefinitions["Contribute"]);
i.RoleAssignments.Add(roleAssignment);
web.AllowUnsafeUpdates = true;
i.Update();
web.Update();
web.AllowUnsafeUpdates = false;
}
// Capture the temporary files
foreach(SPFile file in projSubFolder.Files) {
if (file.Name.ToLower().Contains("temporary document delete me")) {
files2Delete.Add(file);
}
}
}
// Delete Temporary Files
foreach(SPFile f in files2Delete) {
f.Delete();
f.ParentFolder.Update();
}
}
}
}
}
}
Solution
You'll want to use i.BreakRoleInheritance(false) on this one, instead of true.
"
When you call SPItem.BreakRoleInheritance(true), you are assigning the list item with unique permissions, while copying existing permissions on the list to the item. Any new permissions added to the item are only applied to the item.
When you call SPItem.BreakRoleInheritance(false), you are assigning the list item with unique permissions. Existing permissions on the list are NOT copied to the list item. Any new permissions added to the item are only applied to the item.

OTHER TIPS
Your code should work from what I can see, haven't tested it. But you use i.BreakRoleInheritance(true);
, meaning it will copy all the permissions it has before breaking the inheritance (from the parent). Are you sure it does not say "This folder has unique permissions." when you check the permission of the SubFolders in the GUI?
