如何以编程方式删除所有主流浏览器（IE、Firefox、Opera、Chrome 和 Safari）中的 cookie、缓存和历史记录（即所有浏览数据）？
我发现以下博客条目详细介绍了完成任务的批处理脚本：http: //www.catonmat.net/blog/clear-privacy-ie-firefox-opera-chrome-safari/
但我想将这些转换为 C#。
我有 WinINETCache 类，但我在这个命令附近有一些错误......
代码描述行
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));
我想知道我必须调用哪个库才能成功执行。课程如下 - 我该如何称呼这个课程？
