错误试图删除当前成员

Question

我有一个.NET用户控件在Umbraco网站上运行，我希望能够从代码隐藏中删除当前成员（我意识到这听起来不像一个伟大的计划，但这并在一个正常的ASP.NET窗体现场工作），但调用System.Web.Security.Membership.DeleteUser(usernameToDelete, trueOrFalse);给我（的页面，我重定向到）上：

No member with username '[email protected]' exists 
Exception Details: System.Configuration.Provider.ProviderException: No member with username '[email protected]' exists 
[ProviderException: No member with username '[email protected]' exists] 
    umbraco.providers.members.UmbracoProfileProvider.SetPropertyValues(SettingsContext context, SettingsPropertyValueCollection collection) +346 
    System.Configuration.SettingsBase.SaveCore() +402 
    System.Configuration.SettingsBase.Save() +109 
    System.Web.Profile.ProfileBase.SaveWithAssert() +31 
    System.Web.Profile.ProfileBase.Save() +72 
    System.Web.Profile.ProfileModule.OnLeave(Object source, EventArgs eventArgs) +9025062 
    System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +148 
    System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75 

为什么尝试设置属性值我有后删除了用户并更改了页面？我看不到如何设置/删除当前的Umbraco会员。

编辑：我使用的是一把umbraco v 4.11.1（议会版本：1.0.4715.27659）

这里是我的注销代码最长的版本，我已经试过了还是给出了错误：

// 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: 
//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);

如果在删除代码之前从代码隐藏中注销当前用户，会发生什么情况？

它看起来像被删除的用户仍然登录并存在于当前会话，因此一把umbraco profileprovider试图用它做什么...

编辑： 尝试FormsAuthentication注销后，这2种方法，看看如果它可以帮助：

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

EDIT2：

我看着UmbracoProfileProvider类，看看是什么原因造成的错误：

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; 
       } 

      } 

您可以在提供者试图根据用户名检索当前成员后看到您的异常消息。 无论哪种方式你的上下文仍然包含一个用户名或SettingsPropertyValueCollection计数是> 0，所以它似乎你的代码注销成员仍然留下一些东西。

试试这部分，而不是你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); 

这消除并清除缓存和客户端，标志成员出来，删除角色的cookie并清除当前会话。最后，注销后，使用其用户名删除成员。
