调用系统默认浏览器，打开网页

使用Process.Start("http://www")有些系统会无效，所以，这样比较保险

 string HTTP_KEY = @"Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice";
            if (true)
            {
                var key = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(HTTP_KEY, false);
                var progid = key.GetValue("ProgId").ToString();
                key = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey($"{progid}\\shell\\open\\command",false);
                var value = key.GetValue(null);
                if (value != null)
                {
                    var path = value.ToString();
                    if (path.StartsWith("\""))
                    {
                        var exePath = path.Substring(1);
                        var index = exePath.IndexOf("\"");
                        exePath = exePath.Substring(0, index);
                        index += 2;
                        var args = path.Substring(index);
                        args = args.Replace("%1", "https://www.baidu.com");
                        System.Diagnostics.Process.Start(exePath, args);
                        return;
                    }
                }
            }
