关于System.Timers.Timer控制主线程控件的问题

Question

线程中不要直接控制UI控件，你可以把数据算好，然后通过委托去通知UI更新

Answer 1

        public delegate DoProcess(Chart inputchart,int chartindex,int pointIndex);
        private void RefreshUI(Chart inputchart,int chartindex,int pointIndex)
        {
            if (this.InvokeRequired)
            {
                this.Invoke(new DoProcess(RefreshMainform), new object[]{inputchart,chartindex,pointIndex});
            }
            else
            {
                inputchart.ChartAreas["Default"+chartindex].AxisX.Maximum = pointIndex;
            }
        }        public void threadDo()
        {
             if (chart1.ChartAreas["Default1"].AxisX.Maximum < pointIndex)
             {
                 RefreshUI(chart1, 1, pointIndex);
             }
            if (chart2.ChartAreas["Default2"].AxisX.Maximum < pointIndex)
            {
                RefreshUI(chart2, 2, pointIndex);
            }
            if (chart3.ChartAreas["Default3"].AxisX.Maximum < pointIndex)
            {
                RefreshUI(chart3, 3, pointIndex);
            }
        }
