但是在localhost项目中成功运行.我使用的是asp.net 4.0和mysql.在某些资源中，我必须更改信任级别，但不能更改.因为我的托管公司不允许为此更改Web配置文件主题.如何在不更改Web配置的情况下更改信任级别.如何解决此问题? 预先感谢

But in localhost project succesfully run.I'm using asp.net 4.0 and mysql.In some resources say I have to change trust level but I cannot change.Because my hosting firm doesn't allow web config file change for this subject.How can I change trust level without web config change.How can I solve this problem? Thanks in advance

推荐答案

我猜您正在使用共享主机，因此，如果他们没有授予您权限，则无法更改信任级别.

I guess you are using a shared host, so there's no way you can changed trust level if they don't give you permissions to do it.

您正在使用哪个版本的MySQL连接器? 您是否尝试过将它们复制到项目的\ bin文件夹中? (右键单击MySQL.*参考并设置为"Copy Local = true")

What versions of the MySQL connector are you using? Have you tried copying them to the \bin folder of your project? (right-click on MySQL.* references and setting then to "Copy Local = true")

您是否可以尝试从本地主机连接到数据库服务器，以确保您的连接字符串参数正常?

Are you able to try to connect to your database server from localhost to make sure your connection string parameters are ok?
