自定义会员提供程序错误

Question

我有一个自定义的asp.net成员资格类我建立了一个帮助函数，该函数使用GetUser（）方法将数据库中的值转换为System.Web.Security.MembershipUser对象。

private MembershipUser _converToMembershipUser(MembershipDBModel member) 
    { 

     System.Web.Security.MembershipUser membershipUser = new System.Web.Security.MembershipUser(
     this.Name, 
     member.UserName, 
     member.UserID.ToString(), 
     member.Email, 
     member.PasswordQuestion, 
     member.Comment, 
     member.IsApproved, 
     member.IsLockedOut, 
     member.CreationDate, 
     member.LastLoginDate, 
     member.LastActivityDate, 
     member.LastPasswordChangedDate, 
     member.LastLockedOutDate); 

     return membershipUser; 
    }

这是我不断收到正在调用上述方法时的错误。我不知道如何解决这个问题，所以任何建议都非常受欢迎。

Answer 1

错误： “给定的程序集名称或基本代码无效”

你的类型的属性：

type="TMTechMembershipProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cbae438f5bab0724" 

您的评论：

type="TMTechMembershipProvider.TempMembershipProvider" 

你在你的注释行类型属性

i tend to agree but this is needle in haystack. This is what I thought the Fusion Log Viewer was for to help identify what is failing to load.

SRY，但笑:)

更新1：重新注释：

只是觉得好笑，忍不住。没有伤害，并不意味着什么，我们都在那里。

现在更严重的说法是，它似乎仍然是一个具体的问题。

让我们用asp.net提供者的类型比较行吧：

type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" 

[Provider class (including the namespace)], [dll], [Version], ... 

看来你缺少任一类或DLL。希望能解决它，祝你好运。

Answer 2

这是不太可能是一个代码问题，这是一个dll引用问题。

您需要仔细地查看web.config中的任何“type”，“assembly”或“publicKeyToken”xml属性。最可能的原因是您错误地复制了程序集的公钥标记。我首先检查引用System.Web程序集的任何地方，并确保公钥标记完全正确，并且在任何类型名称中都没有错误拼写。

特别是，在您的web.config中检查provider和membership元素下的add元素中的type属性。此外，如果自定义成员资格类是在单独的dll中实现的，请确定您实际上是从该dll引用了正确版本的System.Web程序集。
