如何使用c＃在winform中的按鈕單擊事件上將多個面板移動到不同位置？

Question

我在一個事件上生成了幾個面板，在這些面板中，我有一個按鈕將刪除該特定面板。 現在，我要在刪除沒有間隙的面板時移動其他面板。 我的面板生成功能是...。

    } 

我正在其他事件上設置特定面板的可見模式

 private void viewscreen_MouseDown(object sender, MouseEventArgs e)
    {
        int i;
        if (e.Button == MouseButtons.Right)
        {
            for (i = 0; i <= 20; i++)
            {
                //string c = Convert.ToString(b);
                //generate_editpanel(c);
                if (b == i)
                {
                    epnl[i].Visible = true;
                }
            }
        }
    }

我正在刪除另一個事件上的特定面板...

public void dropedit(object sender, EventArgs e)
    {
        int i;
        for (i = 0; i <= 20; i++)
        {
            if (cbtn[i].Capture)
            {
                EditPanel.Controls.Remove(epnl[i]);
                epnl[i].Dispose();
            }
        }
    }

所以現在我在刪除面板時會出現間隙，我想將其余面板向左移動並消除該間隙。 任何人都可以幫助...如果您需要其他信息，請告訴我

您可以將FlowLayoutPanel用作面板的容器。
