连接字符串到db访问

Question

我在aspx.cs中完成了一切正常工作的项目。现在是时候看到光，时间发布了。

我还有一个包含数据库“db / database.accdb”

的文件夹

然而，在发布之前，我需要在web.config中添加一个“连接字符串”到BD Access，以便能够修改（如果需要）而无需重新编译应用程序。

这就是我在web.config文件中的内容

<configuration>
  <connectionStrings>
    <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
  </connectionStrings>
  <system.web>
    <compilation debug="true" targetFramework="4.0"/>
    <authentication mode="Windows">
    </authentication>
    <membership>
      <providers>
        <clear/>
        <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/"/>
      </providers>
    </membership>
    <profile>
      <providers>
        <clear/>
        <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/"/>
      </providers>
    </profile>
    <roleManager enabled="false">
      <providers>
        <clear/>
        <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/"/>
        <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/"/>
      </providers>
    </roleManager>
  </system.web>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
  <system.web>
    <identity impersonate="false"/>
    <!-- falso para ISS-->
    </system.web>

  <system.web>
  <authorization> <!-- windows authorization IIS EXPRESS (F4) ENABLE senão dá erro -->
    <deny users = "?" /> <!-- nega acesso utilizadores anónimos -->
    <allow users ="*" /> <!-- dá acesso a todos os utilizadores -->
  </authorization>
  </system.web>

</configuration>
