asp.net会员创建用户错误

Question

我在使用 asp.net 用户成员资格创建用户时遇到问题。成员资格提供程序配置如下-

<add name="SqlProvider" type="System.Web.Security.SqlMembershipProvider"
    connectionStringName="DBConnection" applicationName="App"
    enablePasswordRetrieval="true" enablePasswordReset="true"
    requiresQuestionAndAnswer="false" requiresUniqueEmail="true"
    passwordFormat="Encrypted" />

ASP.net配置应用程序生成的错误如下-

An error was encountered. Please return to the previous page and try again. 

The following message may help in diagnosing the problem: Exception has been thrown by the target of an invocation.
