示例
此示例演示如何为节的 membership 多个属性以声明方式指定值，该属性也可以作为类的成员 MembershipSection 进行访问。
以下配置文件示例演示如何以声明方式为 membership 节指定值。
<system.web>
<membership
defaultProvider="AspNetSqlMembershipProvider"
userIsOnlineTimeWindow="15">
<providers>
<add
name=" AspNetSqlMembershipProvider"
type="System.Web.Security.SqlMembershipProvider, System.Web,
Version=2.0.3600.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a"
connectionStringName="LocalSqlServer"
passwordAttemptThreshold="5"
passwordAttemptWindow="10"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="true"
applicationName="/"
requiresUniqueEmail="false"
passwordFormat="Hashed"
description="Stores and retrieves membership data from
the local Microsoft SQL Server database."
/>
</providers>
</membership>
</system.web>
