SharePoint文档库中文件夹的权限管理

需求:
      有一个文档库, 然后下面有很多的文件夹, 每个文件夹都有不同的权限系统, 因此当需要维护这些权限的时候,非常麻烦. 所以需要一个webpart来管理这些权限的内容.

分析:
     1. 用一个treeview列出文档库中的所有文件夹的内容.
     2. 使用一个gridview列出每个文件夹的权限, 点击不同的文件夹时候显示相应的权限.
     3. gridview有删除的功能.
     4. 可以添加uers到一个group, 把users/groups添加到某些文件夹中.

实现:

1. 创建了一个类显示权限的部分信息：

class Permission<T> { private T _strUsers; private T _strPermissions; public T Users { get { return _strUsers; } set { _strUsers = value; } } public T Permissions { get { return _strPermissions; } set { _strPermissions = value; } } public Permission() { } public Permission(T strUsers, T strPermissions) { _strUsers = strUsers; _strPermissions = strPermissions; } } 

 

   

2. 列出相关文件夹的权限：

List<Permission<string>> GetItemsPermissions(string ItemName) { List<Permission<string>> subListP = new List<Permission<string>>(); SPListItemCollection oSPListItems = currentList.Folders; foreach (SPListItem oSPItem in oSPListItems) { if (oSPItem.Name == ItemName) { SPRoleAssignmentCollection oSPRoles = oSPItem.RoleAssignments; subListP = GetRoles(oSPRoles); } } return subListP; } List<Permission<string>> GetRoles(SPRoleAssignmentCollection oSPRoles) { List<Permission<string>> resultList = new List<Permission<string>>(); foreach (SPRoleAssignment oSPRole in oSPRoles) { SPRoleDefinitionBindingCollection oSPRoleDefinitions = oSPRole.RoleDefinitionBindings; string strPermissionLevelName = string.Empty; foreach (SPRoleDefinition oSPRoleDefinition in oSPRoleDefinitions) { strPermissionLevelName += oSPRoleDefinition.Name + ","; } strPermissionLevelName = strPermissionLevelName.Substring(0, strPermissionLevelName.Length - 1); Permission<string> subPermission = new Permission<string>(oSPRole.Member.Name, strPermissionLevelName); resultList.Add(subPermission); } return resultList; } 

   

3. 删除权限：

void DeleteRole(SPRoleAssignmentCollection oSPRoles, string strGroupName) { foreach (SPRoleAssignment oSPRole in oSPRoles) { if (oSPRole.Member.Name == strGroupName) { SPPrincipal currentPrincipal = oSPRole.Member; oSPRoles.Remove(currentPrincipal); break; } } } // Delete permissions in selected folder. SPListItemCollection oSPListItems = myList.Folders; foreach (SPListItem oSPItem in oSPListItems) { if (oSPItem.Name == strNodeName) { if (!oSPItem.HasUniqueRoleAssignments) oSPItem.BreakRoleInheritance(true); SPRoleAssignmentCollection oSPRoles = oSPItem.RoleAssignments; foreach (string strGroup in ListGroups) { DeleteRole(oSPRoles, strGroup); } } } 

4.  添加user到group：

  int AddUserToGroup(string strUserName, string strGroupName, SPWeb myWeb) { SPUser oSPUser = GetSPUser(strUserName, myWeb); int GroupId = 0; if (oSPUser != null) { SPGroupCollection oSPGroups = myWeb.Groups; foreach (SPGroup oSPGroup in oSPGroups) { if (oSPGroup.Name == strGroupName) { oSPGroup.AddUser(oSPUser); GroupId = oSPGroup.ID; } } } return GroupId; } 

5.  添加users/groups到指定的文件夹中：

// 获得选中的permissions List<string> ListPermissions = new List<string>(); foreach (ListItem Item in CheckBoxListPermissions.Items) { if (Item.Selected) { ListPermissions.Add(Item.Text); } } // 获得user/group if (currentUser != null) { oSPRole = new SPRoleAssignment(currentUser); } else if (currentGroup != null) { oSPRole = new SPRoleAssignment(currentGroup); } foreach (string strRoleDefinition in ListPermissions) { oSPRole.RoleDefinitionBindings.Add(myWeb.RoleDefinitions[strRoleDefinition]); } // 添加到指定的文件夹中 SPListItemCollection oSPListItems = myList.Folders; foreach (SPListItem oSPItem in oSPListItems) { if (!oSPItem.HasUniqueRoleAssignments) oSPItem.BreakRoleInheritance(true); if (oSPItem.Name == strSelectNode) { oSPItem.RoleAssignments.Add(oSPRole); } } 

  

效果:
1.  显示权限的页面:


2. 添加users/groups 的页面.
