问题：“调用目标已抛出异常”！ [英] Problem: "Exception has been thrown by the target of an invocation"!?

问题描述

我创建了自己的注册表并注销了sistem。但是当我运行我的MVC应用程序并选择Logout选项时，Visual Studio会抛出异常：调用目标抛出了异常;在这行代码中：

 LazyInitializer.EnsureInitialized（ ref  _initializer ， ref  _isInitialized， ref  _initializerLock）; 

$ z $ b在InitializeSimpleMembershipAttribute.cs中，Visual Studio自动创建。



LogOff控制器：

  public  ActionResult LogOff（）
 {
 WebSecurity.Logout（）; 
  return  RedirectToAction（  Index，  Home）; 
} 
 

部分档案：

 <％@     Page    语言  =  C＃   继承  =   System.Web.Mvc.ViewPage    ％>  
 <％  if （Request.IsAuthenticated）{< span class =code-pagedirective>％>  
 Hello，<％：User.Identity.Name ％>  <％：Html.ActionLink（  Logout，  LogOff ， 帐户）％>  
 <   ul    < span class =code-attribute> id   =  menu >

 <   / ul  >  
 <％ } ％>  

寄存器控制器：

 [HttpPost] 
  public  ActionResult RegisterUser（Models.Register用户）
 { 
  if （ModelState.IsValid）
 {
注册r =  new 注册（）; 
   #region RegistrationData 
  r.Address = user.AddressField; 
 r.City = user.CityField; 
 r.Country = user.CountryField; 
 r.Email = user.EmailField; 
 r.Name = user.NameField; 
 r.PersonalIdentificationNumber = user.IDField; 
 r.Post = user.PostField; 
 r.TaxNumber = user.TaxNumberField; 
 r.Type = user.AccountTypeField; 
   #endregion 
  
 BankAccount ba = BaService.createBankAccount（r）; 
 FormsAuthentication.RedirectFromLoginPage（ba.Email， false ）; 
 
  return  RedirectToAction（ 索引，  Home）; 
} 
 
  else  
 {
 ModelState.AddModelError（ ，  fdsafdsa< /跨度>）; 
} 
 
  return 查看（用户）; 
} 
 

如果有人知道如何解决这个或我如何实现这个注销系统它会工作..请帮助我。谢谢！

Hi,
i have created my own register and log off sistem. But when i run my MVC application and choose Logout options, Visual Studio throw me an exception: Exception has been thrown by the target of an invocation; in this line of code:

LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);

in InitializeSimpleMembershipAttribute.cs, which Visual Studio automatic created.

LogOff Controller:

public ActionResult LogOff()
{
    WebSecurity.Logout();
    return RedirectToAction("Index", "Home");
}

Partial file:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>
<% if (Request.IsAuthenticated) { %>
Hello, <%: User.Identity.Name%> <%: Html.ActionLink("Logout", "LogOff", "Account")%>
<ul id="menu">
    <li><%: Html.ActionLink("Home", "Index", "Home") %></li>
    <li><%: Html.ActionLink("Add invoice", "CreateInvoice", "Bank")%></li>
</ul>
<% } else { %>
<ul id="menu">
    <li><%: Html.ActionLink("Home", "Index", "Home") %></li>
</ul>                           
<% } %>

Controller for register:

[HttpPost]
public ActionResult RegisterUser(Models.Register user)
{
    if (ModelState.IsValid)
    {
        Registration r = new Registration();
        #region RegistrationData
        r.Address = user.AddressField;
        r.City = user.CityField;
        r.Country = user.CountryField;
        r.Email = user.EmailField;
        r.Name = user.NameField;
        r.PersonalIdentificationNumber = user.IDField;
        r.Post = user.PostField;
        r.TaxNumber = user.TaxNumberField;
        r.Type = user.AccountTypeField;
        #endregion

        BankAccount ba = BaService.createBankAccount(r);
        FormsAuthentication.RedirectFromLoginPage(ba.Email, false);

        return RedirectToAction("Index","Home");
    }

    else
    {
        ModelState.AddModelError("","fdsafdsa");
    }

    return View(user);
}

If anyone has any idea how i can fix this or how i can implements this logout sistem it will work.. please help me. Thanks!

解决方案

My own solution is:

- partial file

<![CDATA[<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>]]>
<![CDATA[<% if (Request.IsAuthenticated) { %>]]>
Hello, <%: User.Identity.Name%> <%: Html.ActionLink("Logout", "Logout", "User")%>


<ul id="menu">
    <li><![CDATA[<%: Html.ActionLink("Domov", "Index", "Home") %>]]></li>
    <li><![CDATA[<%: Html.ActionLink("Dodaj račun", "CreateInvoice", "Bank")%>]]></li>
</ul>
<![CDATA[<% } else { %>]]>
<ul id="menu">
    <li><![CDATA[<%: Html.ActionLink("Domov", "Index", "Home") %>]]></li>
</ul>                           
<![CDATA[<% } %>]]>

- controller

public ActionResult Logout()
{
    FormsAuthentication.SignOut();

    return RedirectToAction("Index", "Home");
}
