下面的代码示例演示了一个 ASP.NET 应用程序的 Web.config 文件，该应用程序将 ASP.NET 成员资格提供程序用于 Forms 身份验证并要求对所有用户进行身份验证。
<configuration>
<connectionStrings>
<add name="SqlServices" connectionString="Data Source=MySqlServer;Integrated Security=SSPI;Initial Catalog=aspnetdb;" />
</connectionStrings>
<system.web>
<membership defaultProvider="SqlProvider" userIsOnlineTimeWindow="20">
<providers>
<add name="SqlProvider"
type="System.Web.Security.SqlMembershipProvider"
connectionStringName="SqlServices"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="true"
passwordFormat="Hashed"
applicationName="/" />
</providers>
</membership>
</system.web>
</configuration>下面的代码示例演示使用 Forms 身份验证和 ASP.NET 成员资格的 ASP.NET 应用程序的登录页。
