得到 System.InvalidOperationException：方法失败，出现意外错误代码 64

Question

我正在努力在 C# 控制台应用程序中访问之前获取文件夹的权限，文件夹的路径可能是 ftp.Same 的本地路径正在我的机器上工作但是在生产服务器上部署时它开始抛出错误 System.InvalidOperationException: Method failed with unexpected error code 64.

代码收到的确切错误是

System.InvalidOperationException: Method failed with unexpected error code   64.
at System.Security.AccessControl.NativeObjectSecurity.CreateInternal(ResourceType resourceType, Boolean isContainer, String name, SafeHandle handle, AccessControlSections includeSections, Boolean createByName, ExceptionFromErrorCode exceptionFromErrorCode, Object exceptionContext)
at System.Security.AccessControl.FileSystemSecurity..ctor(Boolean isContainer, String name, AccessControlSections includeSections, Boolean isDirectory)
at System.Security.AccessControl.DirectorySecurity..ctor(String name, AccessControlSections includeSections)
at UploadData.FolderManager.IsConfiguredFolderAccessible(String path, Folder folder)

抛出错误的完整代码是

 private static void IsConfiguredFolderAccessible(string path, Folder folder)
    {
        // If the file can be opened for exclusive access it means that the file
        // is no longer locked by another process.

错误是由调用本机 Windows GetSecurityInfo() 函数产生的。您可以在 NativeObjectSecurity class. Error 64 or 0x40 in hex has the following definition in winerror.h:

的源代码中看到这一点

ERROR_NETNAME_DELETED

The specified network name is no longer available.

所以您的问题很可能与通过网络访问文件夹有关。
