System.Security.SecurityException：请求类型为'System.Security.Permissions.EnvironmentPermission，mscorlib'的权限失败

I get the following error when I tried to run a 'Published' local website.

当我尝试运行“已发布”的本地网站时，我收到以下错误。

Server Error in '/' Application.

After reading some blogs, I added the following in Web.config, but still have the same error.

阅读一些博客后，我在Web.config中添加了以下内容，但仍然有相同的错误。

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

...

Is there any settings in IIS to configure the trust level(I would like to overcome the error without changing code behind files) ?

IIS中是否有任何设置来配置信任级别（我想在不更改文件后面的代码的情况下克服错误）？

If you have an access to the IIS Manager (inetmgr), you can set the trust level of you application :

如果您可以访问IIS管理器（inetmgr），则可以设置应用程序的信任级别：

start > run > inetmgr
开始>运行> inetmgr
select your web site
选择您的网站
click on ".NET Trust Levels"
点击“.NET Trust Levels”
select "Full Trust" in the drop down list
在下拉列表中选择“完全信任”

To change this configuration at a global level of your iis server use the following command line on the server :

要在iis服务器的全局级别更改此配置，请在服务器上使用以下命令行：

appcmd set config /commit:WEBROOT /section:trust /level:Full

Here is the MSDN source for that info : http://technet.microsoft.com/en-us/library/cc753658(WS.10).aspx

If setting trust level to full does not work, you can try changing the application pool user to a user that has access to the path.

如果将信任级别设置为“完全”不起作用，则可以尝试将应用程序池用户更改为有权访问该路径的用户。
