[C#]取得螢幕畫面

C# 取得螢幕畫的方式很容易，直接來看程式碼吧

 using System;  
 using System.Collections.Generic;  
 using System.ComponentModel;  
 using System.Data;  
 using System.Drawing;  
 using System.Linq;  
 using System.Text;  
 using System.Threading.Tasks;  
 using System.Windows.Forms;  
 namespace screenshoot  
 {  
   public partial class Form1 : Form  
   {  
     public Form1()  
     {  
       InitializeComponent();  
     }  
     private static Graphics gfxScreenshot;  
     private static Bitmap bmpScreenshot;  
     private void button1_Click(object sender, EventArgs e)  
     {  
       //最小化程式視窗  
       this.WindowState = FormWindowState.Minimized;  
       //停個一秒避免有最小化殘影  
       System.Threading.Thread.Sleep(1000);  
       //建立一個新的Bitmap  
       bmpScreenshot = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb);  
       //從Bitmap建立一個Graphics  
       gfxScreenshot = Graphics.FromImage(bmpScreenshot);  
       //把螢幕畫面內容複製到Graphics(Screen.PrimaryScreen表示只複製主螢幕)  
       gfxScreenshot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy);  
       //把畫面儲存  
       bmpScreenshot.Save(string.Format(@"d:\temp\{0}.jpg", DateTime.Now.Ticks.ToString()), System.Drawing.Imaging.ImageFormat.Png);  
       //把程式重新顯示在螢幕上  
       this.WindowState = FormWindowState.Normal;  
     }  
   }  
 }  

執行畫面

只要點下儲存螢幕畫面的Button時，程式自動會縮到最小，等截完畫面後，


再回復，之後圖檔就存到D:\temp資料夾中，上述範例只有截取主要螢幕。
