C# 下利用代码创建按钮、定时器和标签

一般在Form1.Designer.cs 文件下的 InitializeComponent 函数中进行   this .SuspendLayout();//公有，在窗体创建时自动创建 Timer控件 1  申明 private System.Windows.Forms. Timer Timer_j; 2  实例化 this .components = new System.ComponentModel. Container (); this .Timer_j = new System.Windows.Forms. Timer ( this .components); 3  设置 // // Timer_j // this .Timer_j.Interval = 5000;//定时器初始化 this .Timer_j.Enabled = true ;//定时器使能 this .Timer_j.Tick += new System. EventHandler ( this .Timer_j_Tick);//添加触发时间 Button控件 1  申明 private System.Windows.Forms. Button button_start; private System.Windows.Forms. Button button_stop; 2  实例化 this .button_start = new System.Windows.Forms. Button (); this .button_stop = new System.Windows.Forms. Button (); 3  设置 // // button_start // this .button_start.Location = new System.Drawing. Point (200, 200); this .button_start.Name = "button_start" ; this .button_start.Size = new System.Drawing. Size (50, 20); this .button_start.Text = "开始" ; this .button_start.TabIndex = 1; // // button_stop // this .button_stop.Location = new System.Drawing. Point (400, 200); this .button_stop.Name = "button_stop" ; this .button_stop.Size = new System.Drawing. Size (50, 20); this .button_stop.Text = "结束" ; this .button_stop.TabIndex = 2; 4  加入窗口 this .Controls.Add( this .button_start); this .Controls.Add( this .button_stop); Label控件 1  申明 private System.Windows.Forms. Label label_dis; 2  实例化 this .label_dis = new System.Windows.Forms. Label (); 3  设置 // // label_dis // this .label_dis.Location = new System.Drawing. Point (200, 100); this .label_dis.Name = "label_dis" ; this .label_dis.AutoSize = true ; //自动调节大小 this .label_dis.Text = "ljj" ; this .label_dis.TabIndex = 4; 4  加入窗口 this .Controls.Add( this .label_dis);
