Answer 1

您必须使用该Controls属性在表单上添加按钮（或任何其他控件），例如：

private void addstrat3_i_Click(object sender, EventArgs e)
{
    panel3strat.Width += 200;
    Button addstrat3_2 = new Button();
    addstrat3_2.Size = new Size(210, 41);
    addstrat3_2.Location = new Point(50,50);
    addstrat3_2.Visible = true; 

    // add control
    this.Controls.Add(addstrat3_2);    
}

您需要将按钮添加到表单中。

this.Controls.Add(addstrat3_2);
