Asp.net 尝试删除当前成员时出错

我有一个运行在Umbraco网站上的.NET usercontrol，我希望能够从codebehind中删除当前成员（我意识到这听起来不是一个很好的计划，但在普通的ASP.NET表单网站上确实有效），但是调用

System.Web.Security.Membership.DeleteUser（usernameToDelete，trueOrFalse）给我（在我重定向到的页面上）：

为什么在我删除了用户并更改了页面之后，它还要尝试设置属性值？我看不到如何设置/删除当前的Umbraco成员


编辑：我正在使用umbraco v 4.11.1（组装版本：1.0.4715.27659）

以下是我尝试过的最长版本的注销代码，仍然会出现错误：

// sort out problems with umbraco caches:
Member.RemoveMemberFromCache(Member.CurrentMemberId());
Member.ClearMemberFromClient(Member.CurrentMemberId());

Roles.RemoveUserFromRole(Page.User.Identity.Name, JobShopRoles.RoleNames.Candidate.ToString());

//logout from: http://stackoverflow.com/questions/412300/formsauthentication-signout-does-not-log-the-user-out
FormsAuthentication.SignOut();
Page.Session.Clear();  // This may not be needed -- but can't hurt
Page.Session.Abandon();

// Clear authentication cookie
HttpCookie rFormsCookie = new HttpCookie(FormsAuthentication.FormsCookieName, "");
rFormsCookie.Expires = DateTime.Now.AddYears(-1);
Page.Response.Cookies.Add(rFormsCookie);

// Clear session cookie 
HttpCookie rSessionCookie = new HttpCookie("ASP.NET_SessionId", "");
rSessionCookie.Expires = DateTime.Now.AddYears(-1);
Page.Response.Cookies.Add(rSessionCookie);
// Invalidate the Cache on the Client Side

Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);
Page.Response.Cache.SetNoStore();
//END logout

System.Web.Security.Membership.DeleteUser(currentUser.UserName, true);

//TODO: this will consistently give an error trying to update a property on a deleted member. Qs:

Response.Redirect("/", false);

   public override void SetPropertyValues(SettingsContext context,
 SettingsPropertyValueCollection collection) {

                string username = (string)context["UserName"];
                bool authenticated = (bool)context["IsAuthenticated"];

                if (String.IsNullOrEmpty(username) || collection.Count == 0)
                    return;

                Member m = Member.GetMemberFromLoginName(username);
                if (m == null)
                    throw new ProviderException(String.Format("No member with username '{0}' exists", username));


                foreach (SettingsPropertyValue spv in collection) {
                    if (!authenticated && !(bool)spv.Property.Attributes["AllowAnonymous"])
                        continue;

                    if (m.getProperty(spv.Name) != null)
                        m.getProperty(spv.Name).Value = spv.PropertyValue;
                }

            }

如果在删除当前用户之前从codebehind注销该用户，会发生什么情况

看起来被删除的用户仍在登录并存在于当前会话中，因此Umbraco profileprovider尝试对其进行处理

编辑：
在FormsAuthentication注销后尝试以下两种方法，看看是否有帮助：

Member.RemoveMemberFromCache(Member.CurrentMemberId());
Member.ClearMemberFromClient(Member.CurrentMemberId());

编辑2：

我查看了UmbracoProfileProvider类，以查看导致错误的原因：

// sort out problems with umbraco caches:
Member.RemoveMemberFromCache(Member.CurrentMemberId());
Member.ClearMemberFromClient(Member.CurrentMemberId());

Roles.RemoveUserFromRole(Page.User.Identity.Name, JobShopRoles.RoleNames.Candidate.ToString());

//logout from: http://stackoverflow.com/questions/412300/formsauthentication-signout-does-not-log-the-user-out
FormsAuthentication.SignOut();
Page.Session.Clear();  // This may not be needed -- but can't hurt
Page.Session.Abandon();

// Clear authentication cookie
HttpCookie rFormsCookie = new HttpCookie(FormsAuthentication.FormsCookieName, "");
rFormsCookie.Expires = DateTime.Now.AddYears(-1);
Page.Response.Cookies.Add(rFormsCookie);

// Clear session cookie 
HttpCookie rSessionCookie = new HttpCookie("ASP.NET_SessionId", "");
rSessionCookie.Expires = DateTime.Now.AddYears(-1);
Page.Response.Cookies.Add(rSessionCookie);
// Invalidate the Cache on the Client Side

Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);
Page.Response.Cache.SetNoStore();
//END logout

System.Web.Security.Membership.DeleteUser(currentUser.UserName, true);

//TODO: this will consistently give an error trying to update a property on a deleted member. Qs:
//http://stackoverflow.com/questions/14899945/error-trying-to-delete-current-member
//http://our.umbraco.org/forum/core/general/38455-Error-trying-to-delete-current-Member
Response.Redirect("/", false);

   public override void SetPropertyValues(SettingsContext context,
 SettingsPropertyValueCollection collection) {

                string username = (string)context["UserName"];
                bool authenticated = (bool)context["IsAuthenticated"];

                if (String.IsNullOrEmpty(username) || collection.Count == 0)
                    return;

                Member m = Member.GetMemberFromLoginName(username);
                if (m == null)
                    throw new ProviderException(String.Format("No member with username '{0}' exists", username));


                foreach (SettingsPropertyValue spv in collection) {
                    if (!authenticated && !(bool)spv.Property.Attributes["AllowAnonymous"])
                        continue;

                    if (m.getProperty(spv.Name) != null)
                        m.getProperty(spv.Name).Value = spv.PropertyValue;
                }

            }

在提供程序尝试基于用户名检索当前成员后，您可以看到异常消息。
无论哪种方式，您的上下文仍然包含用户名，或者SettingsPropertyValueCollection计数大于0，因此您注销成员的代码似乎仍然留下了一些东西

请尝试此部分，而不是您拥有的所有注销代码：

   Member.RemoveMemberFromCache(Member.CurrentMemberId());
   Member.ClearMemberFromClient(Member.CurrentMemberId());
   FormsAuthentication.SignOut();
   Roles.DeleteCookie();
   HttpContext.Current.Session.Clear();
   System.Web.Security.Membership.DeleteUser(usernameToDelete, false);

这将从缓存和客户端中删除和清除成员、注销、删除角色cookie并清除当前会话。最后，在注销后，使用用户名删除该成员。
同样的事情。我很难让FormsAuthentication.SignOut（）正常工作，但在这个优秀网站的帮助下，我删除了一些cookies，使其正常工作。我认为，一旦该成员注销，我就可以很好地删除他们，但我将放弃该会话，因此我不能使用该会话来允许往返，因此这意味着将他们添加到“删除队列”或类似队列中：/请参阅上面的编辑，这可能会有所帮助。如果没有，添加处理注销的代码部分。我将发布我所拥有的代码的最长版本，但仍然无法运行…那么Roles.DeleteCookie（）应该修复它吗？因为我已经有其他的台词了。我会尽快试一试的！只是尝试了同样的问题。我将把这个版本添加到问题中。顺便问一下，您使用的是哪个Umbraco版本？
