winform 窗体最大化 分类： WinForm 2014-07-17 15:57 215人阅读 评论(0) 收藏

1：窗体首次加载时最大化

(1):主窗体

this.WindowState = FormWindowState.Maximized;

//窗体显示中间部分，不显示窗体名称和最小化、最大化、关闭按钮

            this.FormBorderStyle = FormBorderStyle.None;

this.WindowState = FormWindowState.Maximized;

(2):子窗体

设置父窗体的属性：IsMdiContainer=True

Form f = new Form();

            f.MdiParent = this;

f.WindowState = FormWindowState.Maximized;

[转]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)

当前的屏幕除任务栏外的工作域大小

    this.Width = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Width;

    this.Height = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height;



当前的屏幕包括任务栏的工作域大小

this.Width=System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width;

this.Height=System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height;



任务栏大小

this.Width=System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width-System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Width;

this.Height=System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height-System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height;



winform实现全屏显示

WinForm:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

this.WindowState = System.Windows.Forms.FormWindowState.Maximized;

this.TopMost = true;
