Question

我正在尝试使用SharePoint 2013中的ClientContext向用户授予权限。我已完成与Microsoft网站http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.roledefinitionbindingcollection.add.aspx

完全相同的操作

但最后，这部分代码总是返回异常“无法添加具有空角色定义绑定集合的角色分配”：

RoleAssignment oRoleAssignment = w.RoleAssignments.Add(oUser, roleDefBinding);                            
clientContext.ExecuteQuery();

我搜索了网页，发现类似的问题给其他一些用户但没有回复。有什么想法吗？

我的代码：

clientContext.Load(w.RoleDefinitions);
clientContext.ExecuteQuery();
var role = w.RoleDefinitions.Where(r => r.Name == roleName);
if (role.Count() > 0)
{
       RoleDefinition roleMSP = role.First();
       clientContext.Load(w.SiteUsers);
       clientContext.ExecuteQuery();
       var user = w.SiteUsers.Where(u=> u.LoginName == "c:0+.w|s-1-5-21-3493872076-3631449775-1555872641-1347");
       if (user.Count() > 0)
       {
             // Create a new RoleDefinitionBindingCollection object.
             RoleDefinitionBindingCollection roleDefBinding = new RoleDefinitionBindingCollection(clientContext);
             roleDefBinding.Add(roleMSP);
             User oUser = user.First() as User;

             clientContext.Load(w.RoleAssignments);
             clientContext.ExecuteQuery();

             RoleAssignment oRoleAssignment = w.RoleAssignments.Add(oUser, roleDefBinding);                            
             clientContext.ExecuteQuery();//Here I get an exception
        }
}

Answer 1

解决！删除了以下代码行：

clientContext.Load(w.RoleAssignments);
clientContext.ExecuteQuery();

看起来你不需要检索Assignements列表，然后添加你的。

Answer 2

为我工作的代码：

 RoleDefinitionCollection roleDefs = web.RoleDefinitions;
 var query = projectCtx.LoadQuery(roleDefs.Where(p => p.RoleTypeKind == RoleType.Contributor));
 projectCtx.ExecuteQuery();
 RoleDefinition roledefObj = query.FirstOrDefault();

 RoleDefinitionBindingCollection collRoleDefinitionBinding = new RoleDefinitionBindingCollection(projectCtx) { roledefObj };
 var roleAssignments = web.RoleAssignments;
 roleAssignments.Add(principalTest, collRoleDefinitionBinding);

 projectCtx.ExecuteQuery();

无法使用空角色定义绑定集合添加角色分配
