C#能否使用读取硬盘上IE浏览器的Cookie然后利用这个进行登录
比如我使用IE登录了人人网，然后使用了下次自动登录，所以相关Cookie存储了相应的信息。然后，我自己写了一个WinForm程序，此时，我能否通过C#去读取IE下的Cookie进行分析，然后使用WebClint或者HttpWebRequest进行登录呢？
[解决办法]
不记得什么时候写的了，仅供参考，楼主可以搜索一下“IE cookie 格式”
public static list<Cookie> get(string url, bool isRemove)
{
list<Cookie> cookies = new list<Cookie>();
if (url != null && url.Length != 0)
{
int index = url.IndexOf("://", StringComparison.Ordinal);
if (index != -1)
{
int pathIndex = url.IndexOf('/', index += 3);
string urlDomain = pathIndex == -1 ? url.Substring(index) : url.Substring(index, pathIndex - index);
if (urlDomain.Length != 0)
{
bool isCookie;
Cookie newCookie;
int lines, startIndex, removeCount;
long expiresLow, expiresHigh;
DateTime expires;
string[] cookieInfos;
bool[] isRemoves;
string domain, path, urlPath = pathIndex == -1 ? "/" : url.Substring(pathIndex);
urlDomain = "." + urlDomain;
foreach (string filename in Directory.GetFiles(Environment.GetFolderPath(Environment.SpecialFolder.Cookies), "*.txt"))
{
try
{
lines = (cookieInfos = File.ReadAllLines(filename)).Length;
isRemoves = isRemove ? new bool[lines] : null;
for (startIndex = lines - 8, removeCount = index = 0; index <= startIndex; index++)
{
isCookie = false;
if (long.TryParse(cookieInfos[index + 4], out expiresLow)
&& long.TryParse(cookieInfos[index + 5], out expiresHigh))
{
expires = DateTime.FromFileTimeUtc((expiresHigh << 32) + expiresLow);
if (expires > date.NowTime)
{
if ((pathIndex = (domain = cookieInfos[index + 2]).IndexOf('/')) == -1)
{
path = "/";
}
else
{
path = domain.Substring(pathIndex);
domain = domain.Substring(0, pathIndex);
}
if (domain[0] != '.') domain = "." + domain;
//if ((domain[0] == '.' ? urlDomain.EndsWith(domain, StringComparison.OrdinalIgnoreCase)

String.Compare(urlDomain, 0, domain, 1, urlDomain.Length, true) == 0 : String.Compare(urlDomain, domain, true) == 0) && urlPath.StartsWith(path, StringComparison.OrdinalIgnoreCase))
isCookie = urlDomain.EndsWith(domain, StringComparison.OrdinalIgnoreCase) && urlPath.StartsWith(path, StringComparison.OrdinalIgnoreCase);
