关于c＃：如何在Medium Trust中写入Web.Config？

将我的第一个大小合适的Web应用程序上载到共享主机，这给我带来了一系列新的挑战，我的意思是不眠之夜。 问题是我最肯定没有开发我的中等信任度应用程序(或有任何线索)。

我缓解了所有问题，保存了一个。

我已经为管理员编写了一个安装程序，以能够指定其连接字符串和其他首选项，但是我找不到以中等信任度写入web.config的方法。 有没有人有解决方案，还是我应该将偏好设置放在另一个文件中？

这实际上听起来像IIS的Low级别。 如果是这样，那么您将无法写入任何文件，而不仅仅是web.config。

以下是IIS帮助文件中的级别：

• Full (internal) - Specifies unrestricted permissions. Grants the ASP.NET application permissions to access any resource that is subject to operating system security. All privileged operations are supported.

• High (web_hightrust.config) - Specifies a high level of code access security, which means that the application cannot do any one of the following things by default:
  • Call unmanaged code.
  • Call serviced components.
  • Write to the event log.
  • Access Message Queuing service queues.
  • Access ODBC, OleDb, or Oracle data sources.
• Medium (web_mediumtrust.config) - Specifies a medium level of code access security, which means that, in addition to High Trust Level restrictions, the ASP.NET application cannot do any of the following things by default:
  • Access files outside the application directory.
  • Access the registry.
  • Make network or Web service calls.
• Low (web_lowtrust.config) - Specifies a low level of code access security, which means that, in addition to Medium Trust Level restrictions, the application cannot do any of the following things by default:
  • Write to the file system.
  • Call the Assert method.
• Minimal (web_minimaltrust.config) - Specifies a minimal level of code access security, which means that the application has only execute permissions.

我建议如果您对安装程序一无所知，请让它在内存中创建一个web.config，用户可以在本地保存，然后再保存FTP。
