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
 
  
 
3. 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.FormBorderStyle. = FormBorderStyle.None; 
         this.MaximumSize = new 
Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height); 
         this.WindowState = FormWindowState.Maximized; 
      } 
   }
 
此时this.FormBorderStyle. 为 None 不会显示窗体标题栏等相关
 
  
 
  
 
窗体最大化的时候，如何指定窗体的位置、大小(C#)

WindowsApplication1

{ 
private 
const long WM_GETMINMAXINFO = 0x24; 
public 
struct POINTAPI 
{ 
public

public

} 
public 
struct MINMAXINFO 
{ 
public

} 
public 
FormRegion() 
{ 
InitializeComponent(); 
this.MaximumSize = new 
Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height); 
} 
protected 
override void WndProc(ref

{ 
base.WndProc(ref

if (m.Msg == WM_GETMINMAXINFO) 
{ 
MINMAXINFO mmi = (MINMAXINFO)m.GetLParam(typeof(MINMAXINFO)); 
mmi.ptMinTrackSize.x = this.MinimumSize.Width; 
mmi.ptMinTrackSize.y = this.MinimumSize.Height; 
if (this.MaximumSize.Width != 0 || this.MaximumSize.Height != 0) 
{ 
mmi.ptMaxTrackSize.x = this.MaximumSize.Width; 
mmi.ptMaxTrackSize.y = this.MaximumSize.Height; 
} 
mmi.ptMaxPosition.x = 1; 
mmi.ptMaxPosition.y = 1; 
System.Runtime.InteropServices.Marshal.StructureToPtr(mmi, m.LParam, true); 
} 
} 
} 
}  
 
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)
