1. 窗体最大化时 非全屏 不会遮盖任务栏
private
void btnFormMax_Click(object
sender, EventArgs e)
{
if
(this.WindowState == FormWindowState.Maximized)
{
this.WindowState = FormWindowState.Normal;
}
else
{
this.WindowState = FormWindowState.Maximized;
}
}
此时this.FormBorderStyle. 默认为 Sizable
2. 窗体最大化时 会全屏 及遮盖任务栏
private
void btnFormMax_Click(object
sender, EventArgs e)
{
if
(this.WindowState == FormWindowState.Maximized)
{
this.WindowState = FormWindowState.Normal;
}
else
{
this.FormBorderStyle. = FormBorderStyle.None;
this.WindowState = FormWindowState.Maximized;
}
}
此时this.FormBorderStyle. 为 None 不会显示窗体标题栏等相关

MessageBox.Show("当前窗体标题栏高度"+(this.Height - this.ClientRectangle.Height).ToString());//获得当前窗体标题栏高度
ClientRectangle//获取表示控件的工作区的矩形
MessageBox.Show(SystemInformation.PrimaryMonitorSize.ToString()); //获取主显示器屏幕的尺寸(像素)
//获取主显示器当前当前视频模式的尺寸(以象素为单位)
MessageBox.Show("菜单栏高度"+SystemInformation.MenuHeight.ToString()); //获取标准菜单栏的高度
MessageBox.Show("标题栏高度"+SystemInformation.CaptionHeight.ToString()); //获取标准标题栏的高度
MenuHeight//获取一个菜单行的高度(以象素为单位)
CaptionHeight//获取窗口的标准标题栏区域的高度(以象素为单位)
