关于winForm窗体最大化的设置(转)

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#)

using System; 

using System.Collections.Generic; 

using System.ComponentModel; 

using System.Data; 

using System.Drawing; 

using System.Text; 

using System.Windows.Forms; 

namespace WindowsApplication1 

{ 

public partial class FormRegion : Form. 

{ 

private const long WM_GETMINMAXINFO = 0x24; 

public struct POINTAPI 

{ 

public int x; 

public int y; 

} 

public struct MINMAXINFO 

{ 

public POINTAPI ptReserved; 

public POINTAPI ptMaxSize; 

public POINTAPI ptMaxPosition; 

public POINTAPI ptMinTrackSize; 

public POINTAPI ptMaxTrackSize; 

} 

public FormRegion() 

{ 

InitializeComponent(); 

this.MaximumSize = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height); 

} 

protected override void WndProc(ref System.Windows.Forms.Message m) 

{ 

base.WndProc(ref m); 

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)
