实现Winform端窗体关闭后刷新html网页内容

一、首先要知道刷新网页的路径；

  frmPointEasyToBeat fpetBeat = new frmPointEasyToBeat(bookNoteId, userInfo.UserId);
                 fpetBeat.ShowDialog();
                 if (webBrowser1.Document?.Window?.Frames != null)
                 {
                     foreach (var iFrame in webBrowser1.Document?.Window?.Frames)
                     {
                         HtmlWindow window = (HtmlWindow)iFrame;
                         if (window.Url.ToString().Contains("UploadImagePage.aspx"))
                         {
                             window.Document?.InvokeScript("searchPhoto", new object[] { });
                         }
                     }
                 }

后端向html传递刷新消息
