该程序集不允许部分信任的调用者.的InitializeComponent()

Question

场景:我正在重构我们的一个应用程序以使用Nhibernate,并在几周之前遇到了这个问题.这个问题最初是与Nhibernate和Castle一起解决的,所以他们都重新编译了[assembly: AllowPartiallyTrustedCallers].但是,在对UI和代码库进行一些更改后,此错误再次出现.另外值得注意的是,我从Form_Main以编程方式控制加载我的用户控件.

问题:每当生成用户控件时,我都会收到以下错误.如果我注释掉加载,程序将运行.当我调试它结束于自动生成的InitializeComponent()函数.请注意,我无法进入该功能.

有人对这个问题有任何想法吗？我已经将[assembly:AllowPartiallyTrustedCallers]添加到程序集中.有没有办法找出哪个引用(？)导致此错误？或者通过InitializeComponent()的任何方式？

注意:我包含了所有权限,项目设置为部分信任.

无论如何,非常感谢任何帮助.

Answer 1

好的,如果我要解决这个问题,我会按如下方式处理:

1)如果我使用.NET 4.0,确保这也已经被处理.

2)使用ILDASM或反射器在bin文件夹上打开所有有问题的DLL,以确保AllowPartiallyTrustedCallersAttribute在它们上面设置.

3)AppDomain.CurrentDomain.GetAssemblies()在出错时使用(使用即时窗口)查看从哪里加载哪个组件.我认为这可能是你的问题,因为我经常看到从GAC或各种bin文件夹加载旧的或流氓版本的程序集

我认为使用这3个步骤,您将能够找到您的问题.

Answer 2

对于所有可能错过了Aliostad答案的评论的未来读者.

基本上对我有用的是接受Aliostad的建议并重新编译我可以使用AllowPartiallyTrustedCallersAttribute的所有引用.要验证加载的程序集,我遵循了Aliostad建议的第2步.一旦我确定所有必需的dll都具有该属性,我将该属性包含在我的项目中,然后将我的项目设置为完全信任(不是部分信任).

注意:我使用Microsoft.Office.Interop.Outlook发送电子邮件,它需要完全信任,但仍允许其他dll以部分信任方式运行.

希望这有助于未来的用户.任何问题只需在下面评论.
