Got System.InvalidOperationException：方法失败，出现意外的错误代码64

Question

我正在努力获取文件夹的权限，然后在C#控制台应用程序中访问，文件夹的路径可能是ftp本地.Same正在我的机器上工作，但在生产中部署时服务器其开始投掷错误System.InvalidOperationException: Method failed with unexpected error code 64。

确切的错误接收代码

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) 

完整的代码抛出的错误是

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.

         continue; 

        if (rule.AccessControlType == AccessControlType.Deny) 
        { 
         LogHelper.Log(string.Format("Access permission denied on Folder {0}", path), LogHelper.LogLevel.Error); 
         MailComponent.SendMail(folder.ToString(), string.Format("Access permission denied on Folder {0}", path)); 
        }

通过原生的Windows GetSecurityInfo()函数的调用产生的错误。你可以在NativeObjectSecurity类的源代码中看到这个。错误64或0x40的十六进制具有winerror.h以下定义：

ERROR_NETNAME_DELETED

指定的网络名不再可用。

因此，您的问题很可能与通过网络访问文件夹相关。
