            }        }以上是代码，在调试模式下能正常运行，直接运行exe文件时，处理16条数据后，窗体无响应。
急需！ 先谢谢各位高手了！！

把这个 /// <summary> 
        /// 设置获取的新闻标题委托 
        /// </summary> 
        /// <param name="table"> </param> 
        delegate void SetQA(); 
        private void SetQACatalogues() 
        { 
          
                dgvQACatalogue.DataSource = _tbQACatalogueList; 
                dgvQACatalogue.Refresh(); 
                System.Threading.Thread.Sleep(5); 
            
        } 修改为
/// <summary>
        /// 设置获取的新闻标题委托
        /// </summary>
        /// <param name="table"></param>
        delegate void SetQA(int gatherQAID, string qATitle);
        private void SetQACatalogues(int gatherQAID, string qATitle)
        {
            DataRow  row = _tbQACatalogueList.NewRow();
            row["GatherQAID"] = gatherQAID;
            row["QATitle"] = qATitle;
            row["QAStatus"] = "未处理";
            _tbQACatalogueList.Rows.Add(row);
           dgvQACatalogue.Refresh();
           System.Threading.Thread.Sleep(5);
           
            
        }
