C# Winform多屏幕多显示器编程技巧实例
投稿：junjie
这篇文章主要介绍了C# Winform多屏幕多显示器编程技巧实例,本文直接给出代码实例,需要的朋友可以参考下
在窗口的中间有一个System.Windows.Forms.PictureBox控件（该控件区域的面积为所在窗口的1/4），当该控件的大部分区域落在其中一台显示器时，在另一台显示器将不显示该控件，（该PictureBox控件将移动到主显示器所在的窗口区域）。
实现方法:
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace WindowsApplication12
/// <summary>
/// Summary description for Form1.
/// </summary>
public class Form1 : System.Windows.Forms.Form
private int tmpx = 0;
private int tmpy = 0;
private System.Windows.Forms.PictureBox pictureBox1;
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.Container components = null;
System.Drawing.Rectangle[] ScreensRect;
public Form1()
// Required for Windows Form Designer support
InitializeComponent();
// TODO: Add any constructor code after InitializeComponent call
/// <summary>
/// Clean up any resources being used.
/// </summary>
protected override void Dispose( bool disposing )
if( disposing )
if (components != null)
components.Dispose();
base.Dispose( disposing );
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
this.pictureBox1 = new System.Windows.Forms.PictureBox();
this.SuspendLayout();
// pictureBox1
this.pictureBox1.BackColor = System.Drawing.SystemColors.HotTrack;
this.pictureBox1.Location = new System.Drawing.Point(120, 88);
this.pictureBox1.Name = "pictureBox1";
this.pictureBox1.Size = new System.Drawing.Size(248, 176);
this.pictureBox1.TabIndex = 0;
this.pictureBox1.TabStop = false;
// Form1
this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
this.ClientSize = new System.Drawing.Size(504, 357);
this.Controls.Add(this.pictureBox1);
this.Name = "Form1";
this.Text = "Form1";
this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseDown);
this.Load += new System.EventHandler(this.Form1_Load);
this.MouseUp += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseUp);
this.ResumeLayout(false);
#endregion
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
Application.Run(new Form1());
private void Form1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
this.tmpx = e.X;
this.tmpy = e.Y;
this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.form1_MouseMove);
private void Form1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
this.MouseMove -= new System.Windows.Forms.MouseEventHandler(this.form1_MouseMove);
System.Drawing.Rectangle pictureBox1Rect=Screen.GetWorkingArea(pictureBox1);
for(int i=0;i<ScreensRect.Length;i++)
if(ScreensRect[i].X==pictureBox1Rect.X && ScreensRect[i].Y==pictureBox1Rect.Y)
this.Location=new Point(ScreensRect[i].X,pictureBox1Rect.Y);
//MessageBox.Show(" WorkingArea:" + re.ToString());
private void form1_MouseMove(object sender, MouseEventArgs e)
this.Location = new System.Drawing.Point(this.Location.X + e.X - this.tmpx, this.Location.Y + e.Y - this.tmpy);
private void Form1_Load(object sender, System.EventArgs e)
Screen[] s=Screen.AllScreens;
ScreensRect=new Rectangle[s.Length];
for(int i=0;i<s.Length;i++)
ScreensRect[i]= s[i].WorkingArea;
