[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern int SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int y, int Width, int Height, int flags);

[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern System.IntPtr GetForegroundWindow();
哪个窗体想要置顶,在Form_Load中加上
SetWindowPos(this.Handle, -1, 0, 0, 0, 0, 1 | 2); //最后参数也有用1 | 4
具体说明,看API函数说明
如果是用点击一个按钮后弹出新窗体,并置顶,则:
Form2 frm = new Form2();
frm.Show();
SetWindowPos(GetForegroundWindow(), -1, 0, 0, 0, 0, 1 | 2);
