                        this.lvImg.Items.Add(lvi);
                        Thread.Sleep(200);
                    }
                    this.lvImg.EndUpdate();
                }

                if (openCertDialog.FileNames.Length > 0)
                {
                    StringBuilder strSb = new StringBuilder();
                    foreach (var item in openCertDialog.FileNames)
                    {
                        strSb.Append(item + ",");
                    }
                    string names = strSb.ToString().Substring(0, strSb.ToString().Length - 1);
                    if (!string.IsNullOrEmpty(visitEmergencyModel.VtRlatpicidLst))
                    {
                        visitEmergencyModel.VtRlatpicidLst = visitEmergencyModel.VtRlatpicidLst + "," + names;
                    }
                    else
                    {

        {
            if (selectImage != null)
            {
                if (this.lvImg.Items.Contains(selectImage))
                {
                    this.lvImg.Items.Remove(selectImage);
                }
