用FormBrowserServer方法时出现错误

Open bingdengtan opened this issue 5 years ago • 2 comments

        using (OpcUaHelper.Forms.FormBrowseServer form = new FormBrowseServer())
        {
            form.ShowDialog();
        }

在地址上填上我本地的OPC UA server 地址,点击Connect(我的OPC server是Prosys OPC UA Simulation Server), 出现以下错误,请帮忙看看,谢谢!!
