如何在c#浏览器中更改选项卡页时更改收藏夹图标？

webBrowser1.Navigate("http://www.example.com");

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    // 在这里进行收藏夹图标的更改操作
}

using System.Runtime.InteropServices;

[DllImport("urlmon.dll", CharSet = CharSet.Auto)]
private static extern int SetFavicon(string pszPath, string pszUrl, int dwFlags);

private const int FAVICON_LOADFROMFILE = 0x00000001;

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    // 设置收藏夹图标的路径和URL
    string iconPath = "C:\\path\\to\\favicon.ico";
    string url = "http://www.example.com";

    // 调用SetFavicon函数来更改收藏夹图标
    SetFavicon(iconPath, url, FAVICON_LOADFROMFILE);
}
