新添加一个button?
在Form1类中加上:
private System.Windows.Forms.Button btn;
然后在你那个button1_Click事件里写:
this.btn = new Button(); //创建一个新的Button对象实例
this.btn.Location = new System.Drawing.Point(200, 90); //这些是设置新Button的属性
this.btn.Name = "btn";
this.btn.TabIndex = 12;
this.btn.Text = "aaaaaaaaaaa";
this.Controls.Add(this.btn); //添加Button
