我需要从我的窗体中删除标题栏.但是,当我设置
FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
我丢失了标题栏,但同时我看不到任务栏.
所以我需要通过删除标题栏来恢复任务栏.我需要像在附加图片中那样
有人可以帮我吗?
最佳答案 一种方法是告诉窗口最大边界是什么.您可以通过覆盖WM_GETMINMAXINFO窗口消息的默认行为来实现.所以基本上你必须覆盖窗体的WndProc方法.
您还可以更改MaximizedBounds(受保护属性)的值,而不是覆盖WndProc,但如果这样做,则每次将表单移动到另一个屏幕时都必须设置此属性.

public class POINT

public POINT(int x, int y)
{
this.x = x;
this.y = y;
}
}

public class MINMAXINFO
{
public POINT ptReserved;
public POINT ptMaxSize;
public POINT ptMaxPosition;
public POINT ptMinTrackSize;
public POINT ptMaxTrackSize;
}
protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
const int WM_GETMINMAXINFO = 0x0024;
if (m.Msg == WM_GETMINMAXINFO)
{
MINMAXINFO minmaxinfo = (MINMAXINFO)m.GetLParam(typeof(MINMAXINFO));
var screen = Screen.FromControl(this);
minmaxinfo.ptMaxPosition = new POINT(screen.WorkingArea.X, screen.WorkingArea.Y);
minmaxinfo.ptMaxSize = new POINT(screen.WorkingArea.Width, screen.WorkingArea.Height);
Marshal.StructureToPtr(minmaxinfo, m.LParam, false);
}
