すべての主要なブラウザー (IE、Firefox、Opera、Chrome、Safari) で、Cookie、キャッシュ、および履歴 (つまり、すべての閲覧データ) をプログラムで削除するにはどうすればよいですか?
このタスクを実行するためのバッチ スクリプトについて詳しく説明している次のブログ エントリを見つけました 。
しかし、これらをC#に変換したいと思います。
私は WinINETCache クラスを持っていますが、このコマンドの近くにエラーがあります...
コード説明行
long fileTime = (internet_cache_entry_infoa.LastModifiedTime.dwHighDateTime << 0x20) | ((long)((ulong)internet_cache_entry_infoa.LastModifiedTime.dwLowDateTime));
long num5 = (internet_cache_entry_infoa.LastAccessTime.dwHighDateTime << 0x20) | ((long)((ulong)internet_cache_entry_infoa.LastAccessTime.dwLowDateTime));
long num6 = (internet_cache_entry_infoa.LastSyncTime.dwHighDateTime << 0x20) | ((long)((ulong)internet_cache_entry_infoa.LastSyncTime.dwLowDateTime));
long num7 = (internet_cache_entry_infoa.ExpireTime.dwHighDateTime << 0x20) | ((long)((ulong)internet_cache_entry_infoa.ExpireTime.dwLowDateTime));
正常に実行するために呼び出す必要があるライブラリを知りたいです。クラスは以下のとおりです。このクラスをどのように呼び出すことができますか?
