'System.Security.Permissions.SecurityPermission，mscorlib，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089'失败

标签： c# mysql asp.net security mysql-error-1064

我在主机上部署了我的ASP.NET项目但是失败了。我试图解决这个问题几个小时，但不能。 在我的第一页上，用户在点击登录按钮导航菜单后输入电子邮件和密码。所有数据都存储在mysql db中。发布后我无法在bin文件夹中看到mysqldata.dll，所以我手动添加了。

请帮我解决这个问题。我应该在2天内部署。

我正在尝试登录时显示此问题。

这是web.config文件; 

<?xml version="1.0" encoding="utf-8"?>

我曾尝试在web.config文件中添加<trust level="Medium" />，但之后甚至第一页都无法显示并放弃了问题。

试试这个。 放入你的Web.config。

<system.web>
 <securityPolicy>
   <trustLevel name="Full" policyFile="internal"/>
 </securityPolicy>
</system.web>

关于mysqldata.dll，转到引用，单击mysqldata.dll，右键，属性，然后检查Copy Local是否设置为true。

希望它有所帮助。

<强>解

在我设置应用程序框架v3.5之后，我与我的主机公司进行了交谈并设置了TRUST LEVEL FULL。

我是怎么做到的？

右键单击项目 - 属性 - 从左侧栏中选择应用程序 - 选择目标框架3.5。在这些发布和部署之后。

我的web.config看起来像这样;

答案 2 :(得分：0)

首先，您必须在此路径中打开web.config文件：C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config
第二，你必须在章节下找到这一行 system.web
trust level="Medium" originUrl=""
最后：你必须改变它：
trust level="Full" originUrl=""

如果您将进行此更改，则可以解决您的安全问题。
