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）？
我找到了以下博客条目，详细说明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，但是这个命令附近有一些错误...
CodeDescription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：我怎么称这个班级？

转换所有脚本对论坛答案来说太过分了。
您应该查看DirectoryInfo和FileInfo类。他们应该帮助您将80％的批处理命令转换为c＃。
以下示例代码将删除C：\ TempFiles中的所有文件和目录（包括子目录）（使用它而不是del命令）：
DirectoryInfo dInfo = new DirectoryInfo(@"C:\TempFiles\");
foreach (FileInfo fi in dInfo.GetFiles())
{
// You could also check the file Extension here.
if (fi.Exists())
{
fi.Delete();
}
}
foreach (DirectoryInfo di in dInfo.GetDirectories())
{
if (di.Exists())
{
di.Delete(true);
}
}
