Question

使用Twitterizer框架的任何人是否有在中型信任环境中运行它的经验？我一直在获得安全例外......

安全例外
  说明：   应用程序试图执行   证券不允许操作   政策。授予此应用程序   必要的许可请联系   您的系统管理员或更改   应用程序的信任级别   配置文件。

异常详细信息：   System.Security.SecurityException：   该组件不允许部分   值得信赖的来电者。

Answer 1

我在GoDaddy中使用它并且必须找到另一个托管公司，折扣asp.net ...

我很确定Twitterizer的问题是你需要能够进行反射工作，以便程序集识别出可能的操作。中等信任不允许反射起作用。

Answer 2

与godaddy无关，请查看他们在网站上说的内容：

What Is Medium trust level and how does it affect my hosting account?

所以你只有两种方式：

更改Twitterizer信任模式。

OR

检查另一家托管公司。

More about ASP.NET Trust Levels

Answer 3

我正在修改和测试Twitterizer以中等信任方式工作，并将在我的GoDaddy托管上进行测试。

如果您遇到特定问题，请不要犹豫，创建问题单或通过电子邮件发送我们的Google论坛。
