上面一个是VB.NET的
求C#无边框窗体最大化后不档住任务栏的解决办法

[cpio]

主要是最大化后，把窗口置前

[cpio]

新建一个窗口，放一个button，就两行代码就可以的，你试试看
private void button1_Click(object sender, EventArgs e)
{
FormBorderStyle = FormBorderStyle.None;
WindowState = FormWindowState.Maximized;
}

[cpio]

要是还不放心，可以置顶


FormBorderStyle = FormBorderStyle.None;
WindowState = FormWindowState.Maximized;

TopMost = true;//置顶

呵呵，我也想到这个方法了

[wangxiao2008]

学习一下

我不是要最前，是不要 档住任务栏
和普通窗口最大化一样的效果，也就是不要全屏

[ZengHD]

晕，标题有歧义啊

[liujb526]

呵呵，帮顶顺便学习

[CloneCenter]

无边框的窗体，你如何最大化？用代码？用户肯定是没有办法操作的。

所以这里就不要想什么最大化了，修改一下窗体的 Size 即可！Top和Left属性设置为-1，Width和Height设置为Screen.WorkingArea.Width + 2和 Height + 2。试试看……

[wangyanboq]

ME.MaximizedBounds=System.Windows.Forms.Screen.PrimaryScreen.WorkingArea;

[shangwei97]

关注，应该不会太难吧，
我做windows mobile 的全屏

[littlelam]

原来能设置。。。。
MaximizedBounds

[wangyanboq]

还有一种方法是在form的form.designer.vb中设置
me.MaxinumSize = new System.Drawing.Size(System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Width, System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height)

[miss987]

得分回复需要阅读

[niulei]

Me.MaximizeBox = False
Me.MaximizedBounds = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea

[Ericly]

[Quote=引用 15 楼 的回复:]

Me.MaximizeBox = False
Me.MaximizedBounds = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea
[/Quote]


可以在窗体组件初始化完后，加入
this.MaximizedBounds = Screen.PrimaryScreen.WorkingArea;
或
this.Size = Screen.PrimaryScreen.WorkingArea.Size;
