錯誤試圖刪除當前成員

Question

我有一個.NET用戶控件在Umbraco網站上運行，我希望能夠從代碼隱藏中刪除當前成員（我意識到這聽起來不像一個偉大的計劃，但這並在一個正常的ASP.NET窗體現場工作），但調用System.Web.Security.Membership.DeleteUser(usernameToDelete, trueOrFalse);給我（的頁面，我重定向到）上：

No member with username 'test10@test.test' exists 
Exception Details: System.Configuration.Provider.ProviderException: No member with username 'test10@test.test' exists 
[ProviderException: No member with username 'test10@test.test' 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 

爲什麼嘗試設置屬性值我有後刪除了用戶並更改了頁面？我看不到如何設置/刪除當前的Umbraco會員。

編輯：我使用的是一把umbraco v 4.11.1（議會版本：1.0.4715.27659）

這裏是我的註銷代碼最長的版本，我已經試過了還是給出了錯誤：

// 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);

如果在刪除代碼之前從代碼隱藏中註銷當前用戶，會發生什麼情況？

它看起來像被刪除的用戶仍然登錄並存在於當前會話，因此一把umbraco profileprovider試圖用它做什麼...

編輯： 嘗試FormsAuthentication註銷後，這2種方法，看看如果它可以幫助：

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

EDIT2：

我看着UmbracoProfileProvider類，看看是什麼原因造成的錯誤：

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; 
       } 

      } 

您可以在提供者試圖根據用戶名檢索當前成員後看到您的異常消息。 無論哪種方式你的上下文仍然包含一個用戶名或SettingsPropertyValueCollection計數是> 0，所以它似乎你的代碼註銷成員仍然留下一些東西。

試試這部分，而不是你擁有的所有註銷代碼：

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

這消除並清除緩存和客戶端，標誌成員出來，刪除角色的cookie並清除當前會話。最後，註銷後，使用其用戶名刪除成員。
