Question

我已经准备好将应用程序上传到托管服务器，但是当我在服务器上传文件时，我收到此错误：

＆＃39; /＆＃39;中的服务器错误应用

配置错误

描述：处理为此请求提供服务所需的配置文件时发生错误。请查看下面的具体错误详细信息并相应地修改配置文件。

分析程序错误消息：此配置部分不能在此路径中使用。当站点管理员使用＆lt; location allowOverride =＆＃34; false＆＃34;＆gt;锁定对此部分的访问权限时会发生这种情况。来自继承的配置文件。

来源错误：

服务器上发生应用程序错误。此应用程序的当前自定义错误设置可防止远程查看应用程序错误的详细信息（出于安全原因）。但是，它可以在本地服务器计算机上运行的浏览器中查看。

托管服务台说他们无法更改服务器配置，因此我的web.config文件如下：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location allowOverride="true">
  <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Lampino.mdf;Integrated Security=True" providerName="System.Data.SqlClient"/>
  </connectionStrings>

    <system.web>
      <globalization uiCulture="pl-PL" culture="pl-PL" fileEncoding="utf-8" responseEncoding="utf-8" requestEncoding="utf-8"/>
      <compilation debug="true"/>
      <customErrors mode="Off"/>
      <securityPolicy>
        <trustLevel name="Full"/>
      </securityPolicy>
    </system.web>
  </location>
</configuration>

是否有任何选项可以在此主机上运行，还是应该找到新主机？也许我的web.config文件确实存在问题？

与解决IIS问题的方式相同，但没有任何改变。此外，我无法访问服务器配置......

修改当我删除trustLevel标签时收到此错误消息：

Server Error in '/' Application.

Security Exception

Answer 1

现在的ASP.NET版本现在只支持完全信任。您需要找到支持完全信任的托管服务提供商。例如asphostportal或hostforlife

Answer 2

要使用.mdf文件，您需要具有完整信任级别（有关详细信息，请参阅实体框架和通用提供商部分）。

您的托管服务提供商不允许您更改信任级别，因此使用<trustLevel name="Full"/>指令会导致原始错误。

删除<trustLevel name="Full"/>指令原始错误已解决但由于您的Web应用程序仍需要运行完整信任级别，您的托管服务提供商不提供此安全例外。

Answer 3

write \\ in connectionstring.

 <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=(LocalDB)\\v11.0;AttachDbFilename=|DataDirectory|\\Lampino.mdf;Integrated Security=True" providerName="System.Data.SqlClient"/>
  </connectionStrings>
