在作winform程序时遇到窗口如果全屏时，遮盖任务栏的问题，从网上搜到如下解决办法，与各位共享。以下代码本人都试过，没问题：

1.  
  执行如下按钮事件  
  private void btnFormMax\_Click(object sender, EventArgs e)  
  \{  
     if (this.WindowState == FormWindowState.Maximized)  
     \{  
         this.WindowState = FormWindowState.Normal;  
     \}  
     else  
     \{  
         this.WindowState = FormWindowState.Maximized;  
     \}  
  \}  
  窗体最大化时 非全屏 不会遮盖任务栏  
  此时this.FormBorderStyle 默认为 Sizable

2.  
  执行如下按钮事件  
  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;  
      \}  
   \}

窗体最大化时 会全屏 及遮盖任务栏  
  此时this.FormBorderStyle 为 None 不会显示窗体标题栏等相关

3.  
  执行如下按钮事件  
  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;  
      \}  
   \}

窗体最大化时 非全屏 不会遮盖任务栏

\[转\]c\# winform 获取标题栏 状态栏 菜单栏的高度   
[http://heisetoufa.javaeye.com/blog/237640][http_heisetoufa.javaeye.com_blog_237640]   
  
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)
