Got System.InvalidOperationException：メソッドが予期しないエラーコード64で失敗しました

Question

C#コンソールアプリケーションにアクセスする前にフォルダのアクセス権を取得しようとしていますが、フォルダーのパスはftpのローカルになる可能性があります。サーバーは、エラーSystem.InvalidOperationException: Method failed with unexpected error code 64を投げ始めます。

正確なエラーコードで受け取るには、

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) 

スローエラーはエラーがネイティブのWindows GetSecurityInfo()関数の呼び出しによって生成される

で完全なコードです。これはNativeObjectSecurityクラスのソースコードで確認できます。指定されたネットワーク名は利用できません

ERROR_NETNAME_DELETED

：六角でのエラー64または0x40のはwinerror.hで次のように定義していません。

問題は、ネットワーク経由でフォルダにアクセスすることに関連している可能性があります。
