C# Winfrom 窗体上动态生成控件慢处理

处理方式：布局挂起

panelContent.SuspendLayout();

panelContent.ResumeLayout();

 private void button1_Click(object sender, EventArgs e)
        {
            panelContent.SuspendLayout();
            this.panelContent.Controls.Clear();
            string aa = DateTime.Now.ToString();
            int k = 1;
            for (int j = 0; j < 200; j++)
            {
                Add(new QueueButton(), k, this.panelContent, 16, "18.00", "19.00", "Pm");
                k++;
            }
            panelContent.ResumeLayout();
            string bb = DateTime.Now.ToString();

            MessageBox.Show(aa+"\r\n"+bb);
    
        }
