c#介面卡死處理方法

標籤：sync   new   判斷   illegal   color   ogr   ack   end   GridView   

方法一：

設定屬性：

Control.CheckForIllegalCrossThreadCalls = false;

開啟一個新線程

Thread th = new Thread(() => Search(detailID.Trim()));th.IsBackground = true; th.Start();

 public void Search(string detailID){dataGridView1.DataSource =BLLBillConsume.BllGetClearMarketLog_detail(detailID);dataGridView1.Columns[2].DefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomRight;//文本向靠右對齊 }

 

上面的方法不推薦，推薦以下方法：

拖一個組件backgroundWorker

設定屬性：

backgroundWorker1.WorkerReportsProgress = true;backgroundWorker1.WorkerSupportsCancellation = true;

執行用時較長的操作，

backgroundWorker1.CancellationPending是用來判斷是否允許使用者取消

 private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)        {            dtMain = BLLBillConsume.BllGetClearMarketLog_detail(detailID);            if (!backgroundWorker1.CancellationPending)            {//退出                backgroundWorker1.CancelAsync();            }        }

Thread.Sleep(100000);只是為了類比介面卡死

然後就顯示查詢到的資料

 private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)        {            dataGridView1.DataSource = dtMain;            dataGridView1.Columns[2].DefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomRight;//文本向靠右對齊            //Search(detailID.Trim());        }

這個是開啟線程

  backgroundWorker1.RunWorkerAsync();
