类型初始值设定项 "Class" 引发 exception.LoadLibrary 失败

Question

我有一个尝试加载 DLL 的服务。我的服务在我的开发笔记本电脑上运行良好，但在另外两台笔记本电脑上尝试时出现以下异常：

The type initializer for "NanoProtoApi.Interop" threw an exception. --->System.Exception: LoadLibrary failed: C:\Program Files\Proj\x64\Nanomsg.dll.

我已经检查了 dll 位置，它肯定在那里。我不知道发生了什么。有谁知道发生了什么以及如何解决这个问题？

这是异常堆栈跟踪：

这通常意味着库三中的某些class在静态构造期间出现异常。由于发生异常，加载失败。一般来说，图书馆应该考虑到这一点并在加载时处理失败。由于这对您有用，并且堆栈跟踪中有一些网络通信痕迹，我猜测在尝试访问某些远程资源时出现问题。该组件是否需要连接到其他机器？可以从服务器访问这些机器吗？
