private void Add()
        {
            for (int i = 0; i < 100; i++)
            {
                Button button = new Button();
                button.Width = 300;
                button.Height = 200;
                panel1.Controls.Add(button);
                Application.DoEvents();//此處用的話會導致問題
            }
        }
        
 
private void button1_Click(object sender, EventArgs e)
        {
            Add();
        }
        int errorCount = 0;
        private void timer1_Tick(object sender, EventArgs e)
        {
            panel1.Controls.Clear();
            Add();
           
        }

如上代碼，100ms的定時器，執行幾分多鐘後就會崩潰，提示StackOverFlow,推測可能是添加Button時隊列裏有新事件，DoEvents引爆導致。

C#中慎用Application.DoEvents
