当我的ASP.Net网站不允许执行一些由我的虚拟主机服务的安全策略定义的操作时，我该怎么办？

Question

我的用C#编码的asp.net站点在我的本地系统上运行得很好，但是当我通过plesk上传httpdocs文件夹中的文件时，我得到了以下错误：

Answer 1

你需要右击你的项目，然后选择“发布”。你可以发布到文件系统，这样你就可以在上传到Web.config之前修改它，或者你可以只将它设置为发布到so爸爸的网站上。我会选择文件系统方法。一步一步来。

正如您在注释中所说的，“我添加了除项目文件夹中的解决方案文件之外的所有文件和文件夹”，这不会做任何事情。要从中执行，它需要从Visual Studio IDE中运行。要正确设置所有文件用于生产的位置，您必须发布您的web项目。

Answer 2

如果遇到同样的问题，可以使用web.config修复错误。在trust元素中添加level="Full"级别，如下所示：

<system.web>
   ...
   <trust level="Full" />
   ...
</system.web>

Answer 3

您发布的新错误肯定与安全相关。转到网站和域名选项卡。在您的帐户的主域下，单击图标"ASP.NET设置“。当页面加载时，您应该能够在"Code Access Security“下将权限设置为full。试一试，让我们知道它是否有效
