Question

我试图这样做（我的领域），但是当我点击它时我无法看到= false任何按钮。顺便说一句，this.visible = false将以可见的形式出现 - .-

    private void Form1_Load(object sender, EventArgs e)
    {
        this.Size = new Size(541, 537);
        for (int j = 24; j < ClientSize.Height; j += 25)
        {

            for (int i = 0; i < ClientSize.Width; i += 25)
            {
                Button btn = new Button();
                btn.Width = 25;
                btn.Height = 25;
                btn.Location = new Point(i, j);
                btn.Click += btn_Click;
                Controls.Add(btn);

            }
        }

    }

    void btn_Click(object sender, EventArgs e)
    {
       //When i clicked anyone of them that comes be invisible,
    }

thx for help

触发事件的控件存储在sender中 - 将其强制转换为Button。

void btn_Click(object sender, EventArgs e)
{
    var button = (Button)sender;

    button.Hide();
}

或者，如果你在活动中所做的一切，你可以在一行中定义它：

btn.Click += delegate { btn.Hide(); };

按钮cliked时C＃按钮可见更改
