Web.Config 应用配置错误
Web.Config Configuration Error in App
我已经准备好应用程序将其上传到主机上，但是当我在服务器上上传文件时出现此错误：
Server Error in '/' Application.
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: This configuration section cannot be used at this path. This happens when the site administrator has locked access to this section using <location allowOverride="false"> from an inherited configuration file.
Source Error:
An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Hosting Helpdesk 说他们不能更改服务器配置，所以下面是我的 web.config 文件：
<?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这个主机上运行，或者我应该找一个新的？也许我的 web.config 文件真的有问题？
和解决IIS问题的方法一样，但没有任何改变。我也无权访问服务器配置...

当我删除 trustLevel 标签时收到此错误消息：

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。
