推荐答案

我刚刚在MDIParent和MDIChild表单上都尝试过此操作，但是如果将MaximiseBox属性设置为FALSE，则双击标题栏不会执行任何操作，设置如果设置为TRUE，则表示双击将使被单击的窗口最大化.

I have just tried this on both the MDIParent and MDIChild forms, but if you set MaximiseBox property to FALSE, double clicking the titlebar does nothing, setting it to TRUE means a double click causes the clicked window to maximise.

我认为以下内容可能会对某人有所帮助，因为它对我来说非常有效...

I think the below might be of some help to someone, since it worked very finely for me...

Protected Overloads Overrides Sub WndProc(ByRef m As Message)
    'Define DoubleClick...
    Const WM_NCLBUTTONDBLCLK As Integer = &HA3
    'Define LeftButtonDown event...
    Const WM_NCLBUTTONDOWN As Integer = 161
    'Define MOVE action...
    Const WM_SYSCOMMAND As Integer = 274
    'Define that the WM_NCLBUTTONDOWN is at TitleBar...
    Const HTCAPTION As Integer = 2
    'Trap MOVE action...
    Const SC_MOVE As Integer = 61456
    'Disable moving TitleBar...
    If (m.Msg = WM_SYSCOMMAND) AndAlso (m.WParam.ToInt32() = SC_MOVE) Then
        Exit Sub
    End If
    'Track whether clicked on TitleBar...
    If (m.Msg = WM_NCLBUTTONDOWN) AndAlso (m.WParam.ToInt32() = HTCAPTION) Then
        Exit Sub
    End If
    'Disable double click on TitleBar...
    If (m.Msg = WM_NCLBUTTONDBLCLK) Then
        Exit Sub
    End If
    MyBase.WndProc(m)
End Sub

谢谢大家

Thanks guys

尝试一下:

Try this:

private void Form1_Resize(object sender, EventArgs e)
    {
    if (WindowState == FormWindowState.Maximized)
        {
        WindowState = FormWindowState.Normal;
        }
    }

唯一的麻烦是它可能会闪烁:窗口将短暂最大化，然后恢复正常.

The only slight hassle is that it may flicker: the window will be maximized briefly, and then returned to normal.
