自定义ASPNetMembership FailureInformation总是空，OnValidatingPassword问题 [英] Custom ASPNetMembership FailureInformation always null, OnValidatingPassword issue

问题描述

由于此处所述<一href="http://msdn.microsoft.com/en-us/library/system.web.security.membershipprovider.onvalidatingpassword.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/system.web.security.membershipprovider.onvalidatingpassword.aspx

当ValidatingPassword事件完成后，ValidatePasswordEventArgs对象的属性提供作为e参数可以进行检查，以确定当前的行为是否应被取消，如果一个特定的异常，存储在FailureInformation财产，应甩。

"When the ValidatingPassword event has completed, the properties of the ValidatePasswordEventArgs object supplied as the e parameter can be examined to determine whether the current action should be canceled and if a particular Exception, stored in the FailureInformation property, should be thrown."

下面是一些细节/ code这确实说明了为什么FailureInformation可能是空 HTTP：/ /forums.asp.net/t/991002.aspx

Here is some details/code which really shows why FailureInformation could be null http://forums.asp.net/t/991002.aspx

据我的会员设置我应该得到的异常密码不匹配密码的安全状况，但它没有发生。

According with my Membership settings i should get an exception that password does not match password security conditions, but it is not happened.

然后我也尝试调试System.Web.ApplicationServices.dll（在.NET 4.0中位于System.Web.Security中这里）框架code，看什么真的发生在那里，但我不能踏进这个组件，可是因为这个 [TypeForwardedFrom（System.Web程序，版本= 2.0.0.0，文化=中性公钥= b03f5f7f11d50a3a）     公共抽象类的MembershipProvider：的ProviderBase

Then i did try to debug System.Web.ApplicationServices.dll(in .NET 4.0 System.Web.Security located here) Framework Code to see whats really happens there, but i cant step into this assembly, may be because of this [TypeForwardedFrom("System.Web, Version=2.0.0.0, Culture=Neutral, PublicKeyToken=b03f5f7f11d50a3a")] public abstract class MembershipProvider : ProviderBase

轻松我可以走进任何一家其他.NET 4.0组件，但在这一个没有。我没有检查，对System.Web.ApplicationServices.dll符号加载。

Easily i may step into any another .NET 4.0 assembly, but in this one not. I did check, symbols for System.Web.ApplicationServices.dll loaded.

现在我只有一个想法TI如何解决它 - 覆盖方法OnValidatingPassword（ValidatePasswordEventArgs E）

Now i have only one idea how ti fix it - to override method OnValidatingPassword(ValidatePasswordEventArgs e).

这就是我的故事。

可能有人可以帮助：

1）任何想法，为什么OnValidatingPassword不工作？

1) Any ideas why OnValidatingPassword not working?

2）任何想法如何步入它？

2) Any ideas how to step into it?

推荐答案

读过这个 HTTP：/ /forums.asp.net/t/991002.aspx 一次。下面是我的解决方案

Have read this http://forums.asp.net/t/991002.aspx one more time. Here is my solution

    //Override OnValidatingPassword
    protected override void OnValidatingPassword(ValidatePasswordEventArgs args)
    {
        //Any logic to process password validation conditions
        //e.g:
        if (args.Password.Length < MinRequiredPasswordLength)
            args.FailureInformation = new ArgumentException(String.Format("Password is too short, min password length {0}", MinRequiredPasswordLength.ToString()));

        if (args.UserName == args.Password)
            args.FailureInformation = new ArgumentException(String.Format("Password should not be equal to username"));

        //Also here could be any logic to throw an exception if needed
        //e.g:
        if (args.FailureInformation != null)
            throw args.FailureInformation;

        //Calling base
        base.OnValidatingPassword(args);

        if (args.Cancel)
        {
            if (args.FailureInformation == null)
                args.FailureInformation = new ArgumentException(String.Format("Custom Password Validation Failure for password '{0}'", args.Password));

            throw args.FailureInformation;
        }
    }
