关于c# winForm窗体最大化的设置

http://blog.csdn.net/cnkivm/archive/2010/05/30/5635166.aspx

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

}  

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(以象素为单位菜单栏高度"+SystemInformation.MenuHeight.ToString()); //获取标准菜单栏的高度标题栏高度"+SystemInformation.CaptionHeight.ToString()); //获取标准标题栏的高度获取一个菜单行的高度(以象素为单位获取窗口的标准标题栏区域的高度(以象素为单位)
