【问题描述】：

我只能部分让 Lucene .NET 在 GoDaddy 上运行。它会在这一行引发安全异常：

Hits hits = searcher.Search(query, filter);

以下是此异常的详细信息：

Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

在我放弃 GoDaddy 并转向 DiscountASP 之前，我想看看是否有人知道我可以如何调整代码以在中等信任环境中完全运行。

谢谢。

我已经回答了一个关于让 Lucene.Net 在中等信任下工作的不同问题。这是在较新版本的库上。

Lucene.NET in medium trust
