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

//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
