我正在尝试使用以下代码在文档集的子文件夹上打破继承。运行代码并检查文档集的子文件夹,我可以看到它仍然从父级继承。任何人都可以看到这里有什么问题吗?

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();
     }
    }
   }
  }
 }
}
.

有帮助吗?

解决方案

You'll want to use i.BreakRoleInheritance(false) on this one, instead of true.

From this: https://social.technet.microsoft.com/forums/sharepoint/en-US/313effab-a5af-4fda-b39c-37f620fe95f2/itembreakroleinheritancetrue-vs-itembreakroleinheritancefalse

"

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.

其他提示

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?
