“的NullReferenceException：对象未设置为一个对象的实例”与Microsoft.SharePoint.IdentityModel.Pages.FormsSignInPage

我试图让使用基于表单的认证，2010年的SharePoint页面的标志。我跟着一个教程，结束了我的项目显示上述错误（对象未设置为对象的实例）。“的NullReferenceException：对象未设置为一个对象的实例”与Microsoft.SharePoint.IdentityModel.Pages.FormsSignInPage

[NullReferenceException异常：对象引用不设置为一个对象的一个实例] Microsoft.SharePoint.IdentityModel.Pages.FormsSignInPage.OnLoad（EventArgs的）119 NDELogin.Layouts.NDELogin.Login.OnLoad（EventArgs的）+51 System.Web.UI.Control.LoadRecursive（）+65 System.Web.UI.Page.ProcessRequestMain（布尔includeStagesBeforeAsyncPoint，布尔includeStagesAfterAsyncPoint）2427

会有人来看看代码/ ASPX并告诉我你是否看到任何错误。

using System; 
using Microsoft.SharePoint; 
using Microsoft.SharePoint.WebControls; 
using Microsoft.SharePoint.IdentityModel.Pages; 

namespace NDELogin.Layouts.NDELoginc 
{ 
public partial class Login : FormsSignInPage 
    { 
    protected override void OnLoad(EventArgs e) 
    { 
     base.OnLoad(e); 
    } 
    } 
}

我刚才已经回答我自己的问题...在登录控制 – 2012-04-23 22:43:07

您设置的MembershipProvider =“FBAMembershipProvider”设置的MembershipProvider =“FBAMembershipProvider”应该将您的注释回答自己的问题，然后接受它时，通过2天的等待期已到。 – skeletank 2012-04-24 13:36:33

谢谢，我会的 – 2012-04-24 17:46:49

你能否更详细你做了什么解释？你的回答对我来说没有多大意义。 – Anders 2012-11-09 12:57:35
