推荐答案

对于Winforms你可以使用类似这样的东西：

For Winforms you can use something like this:

public Form9()
{
    InitializeComponent();

    var button1 = new Button();
    var button2 = new Button();
    var button3 = new Button();

    // Needs a flowLayoutPanel on your Form.
    this.flowLayoutPanel1.FlowDirection = FlowDirection.TopDown;
    this.flowLayoutPanel1.BackColor = Color.Brown;
    this.flowLayoutPanel1.Controls.Add(button1);
    this.flowLayoutPanel1.Controls.Add(button2);
    this.flowLayoutPanel1.Controls.Add(button3);

    button1.Click += ButtonCollapse;
    button2.Click += ButtonCollapse;
    button3.Click += ButtonCollapse;
}

private void ButtonCollapse(object sender, EventArgs e)
{
    var btn = (Button)sender;

    if (btn.Tag == null)
    {
        btn.Height /= 2;
        btn.Tag = "collapsed";
    }
    else
    {
        btn.Height *= 2;
        btn.Tag = null;
    }
}
