C#利用浏览器获取完整COOKIE示例
使用WebBrowser获取一个网站的COOKIE,在调用Document.Cookie时，发现无法完整获取其COOKIe1.原因：
此 Cookie,加入了。httponly
2.解决方法1: 使用WIN API获取
就可以使用InternetGetCookieEx这个Win API来取得，下面是API的方法宣告
static extern bool InternetGetCookieEx（string pchURL, string pchCookieName, StringBuilder pchCookieData, ref
System.UInt32 pcchCookieData, int dwFlags, IntPtr lpReserved）；
static extern int InternetSetCookieEx（string lpszURL, string lpszCookieName, string lpszCookieData, int dwFlags,
IntPtr dwReserved）；
private static string GetCookies（string url）
{
uint datasize = 256;
StringBuilder cookieData = new StringBuilder（（int）datasize）；
if （！InternetGetCookieEx（url, null, cookieData, ref datasize, 0x2000, IntPtr.Zero））
{
if （datasize < 0）
return null;
cookieData = new StringBuilder（（int）datasize）；
if （！InternetGetCookieEx（url, null, cookieData, ref datasize, 0x00002000, IntPtr.Zero））
return null;
}
return cookieData.ToString（）；
}
实际上它是通过本地COOKIE文件的读取，来取得COOIE的
3.解决方法2:自已写方法读取本地COOKIE文件
public string Cookie（）
2 { www.2cto.com
3 if （this.Url == null）
4 return null;
5 string dir = this.Url.Host;
6 FileStream fr = new FileStream（Environment.GetFolderPath（Environment.SpecialFolder.Cookies） + "
index.dat", FileMode.Open, FileAccess.Read, FileShare.ReadWrite）；
