使.NET WebBrowser不与IE或其他实例共享cookie

由于C#中的WebBrowser与包括IE在内的所有其他WebBrowsers实例共享cookie,我希望WebBrowser拥有自己的cookie容器,该容器不共享之前在IE或其他实例中创建的任何cookie。

因此,例如,当我创建WebBrowser时,它不应该有任何cookie。 当我运行2个WebBrowsers实例时,它们拥有自己的cookie容器,并且不会彼此共享或冲突cookie。

我怎样才能做到这一点?

您可以使用InternetSetOption Win32函数执行此过程:

 [DllImport("wininet.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto, SetLastError = true)] public static extern bool InternetSetOption(int hInternet, int dwOption, IntPtr lpBuffer, int dwBufferLength); 

然后在您的应用程序启动时调用以下函数:

 private unsafe void SuppressWininetBehavior() { /* SOURCE: http://msdn.microsoft.com/en-us/library/windows/desktop/aa385328%28v=vs.85%29.aspx * INTERNET_OPTION_SUPPRESS_BEHAVIOR (81): * A general purpose option that is used to suppress behaviors on a process-wide basis. * The lpBuffer parameter of the function must be a pointer to a DWORD containing the specific behavior to suppress. * This option cannot be queried with InternetQueryOption. * * INTERNET_SUPPRESS_COOKIE_PERSIST (3): * Suppresses the persistence of cookies, even if the server has specified them as persistent. * Version: Requires Internet Explorer 8.0 or later. */ int option = (int)3/* INTERNET_SUPPRESS_COOKIE_PERSIST*/; int* optionPtr = &option; bool success = InternetSetOption(0, 81/*INTERNET_OPTION_SUPPRESS_BEHAVIOR*/, new IntPtr(optionPtr), sizeof(int)); if (!success) { MessageBox.Show("Something went wrong !>?"); } }
