Question

I ve done this sample to try to understand why I m not sending cookies at all with my WebBrowser, it s pretty simple, the form has a WebBrowser on it, that s all:

namespace BrowserTest
{
    public partial class Form1 : Form
    {
        [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern bool InternetSetCookie(string url, string name, string data);

        public static bool SetWinINETCookieString(string url, string name, string data)
        {
            return Form1.InternetSetCookie(url, name, data);
        }

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            // None of two works
            //SetWinINETCookieString("www.nonexistent.com", null, "dataToTest=thisIsTheData");
            SetWinINETCookieString("www.nonexistent.com", "dataToTest", "thisIsTheData");
            this.webBrowser1.Navigate("www.nonexistent.com");
        }
    }
}

而Fidller说的是我寄来的:

“entergraph

象每个人都利用这一职能一样,但对于我来说,我无法工作。我用不同的电脑进行审判,也失败了。任何帮助都是巨大的。

我发现,问题不是检查行动的结果。 www.nonold.com不是一个有效的《国际仲裁裁决汇编》,它必须是。

Answer 2

Just came across this myself.For completeness, you need to check the value returned from InternetSetCookie and if false, call GetLastError which would have given you a return code of 87 - invalid parameter.

i.e.

[DllImport("kernel32.dll")]
public static extern uint GetLastError();

......

bool ok = SetWinINETCookieString("www.nonexistent.com", "dataToTest", "thisIsTheData");
if (!ok)
{
  int errorCode = GetLastError(); //this will return 87  for www.nonexistent.com
}
