Answer 1

阅读错误消息。

[FileLoadException：无法加载文件或程序集'Microsoft.ReportViewer.Common，Version = 9.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'或其依赖项之一。无法授予最低权限请求。（HRESULT异常：0x80131417）]

您尝试在中等信任中使用无法在中等信任中使用的程序集。（Microsoft.ReportViewer.Common）

3个解决方案

A）请求您的托管服务提供商将Microsoft.ReportViewer程序集安装到GAC中（这可能有所帮助），但他们可能不愿意这样做

B）找到一个完全信任或类似的新托管环境

或

B）重写您的应用程序，使其不依赖于该程序集。

如果您正在开发将部署到中等信任环境的应用程序，则应在开发应用程序时设置trust =“medium”，以便在开发期间而不是部署期间发现任何此类问题。

Answer 2

您是否尝试直接从Visual Studio发布功能部署网站？

可能是您的FTP客户端设置了错误的权限。

如果您的报告程序集无法在媒体信任中运行，那么请找一个更好的托管服务提供商，那里有很多：）
