【问题描述】：
我在主机上部署了我的 ASP.NET 项目，但失败了。我试图解决这个问题几个小时，但不能。 在我的第一页上，用户在单击登录按钮后输入电子邮件和密码，他们导航菜单。所有数据都存储在 mysql 数据库中。发布后我在 bin 文件夹中看不到 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。
在我尝试登录后显示此问题。

这是 web.config 文件；
<?xml version="1.0" encoding="utf-8"?>
<configuration>

<add key="webpages:Version" value="2.0.0.0"/>

</connectionStrings>
<system.web>
<customErrors mode="Off" />
<compilation targetFramework="4.0" debug="true"/>

</configuration>
我尝试在 web.config 文件中添加<trust level="Medium" />，但之后连第一页都无法显示并出现问题。

【问题讨论】：
-
您的托管公司是否声称支持 MySql？问题是他们设置了他们的信任级别，因此安全性无法尝试打开连接。您可能需要联系他们的支持以寻找工作示例或切换到支持 MySql 的主机。
-
是的，他们支持 MySql 并且他们的信任级别是中等的。我是 c# 和 asp.net 的新手，所以我的 web.config 文件是真的吗？有什么错误吗？
-
您是否尝试设置
？当您已经处于中等信任状态时，通常会发生这种错误。 -
是的，我试过但没用。
-
@Onur，您需要检查您的 IIS 上的主站点，也许您的网站位于信任级别低的根网站内。 help.webcontrolcenter.com/kb/a1110/…
