使.NET WebBrowser不与IE或其他实例共享cookie

本文关键字:其他 实例 共享 cookie IE NET WebBrowser 不与 | 更新日期: 2023-09-27 18:27:27

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

例如,当我创建一个WebBrowser时,它不应该有任何cookie。当我运行两个WebBrowser实例时,它们有自己的cookie容器,彼此之间不共享或冲突cookie。

我怎样才能做到这一点?

使.NET WebBrowser不与IE或其他实例共享cookie

您可以使用InternetSetOption Win32函数对每个进程执行此操作:

[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 !>?");
    }
}
