c#截图功能

简化版：

using System;
using System.Collections.Generic;
using System.Linq; using System.Text; using System.Threading.Tasks; using System.Drawing; using System.Windows.Forms; using System.IO; using System.Drawing.Imaging; namespace ConsoleApp346 { class Program { [STAThread] static void Main(string[] args) { ScreenCapture(); } static void ScreenCapture() { Rectangle bounds = Screen.GetBounds(System.Drawing.Point.Empty); using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height)) { using (Graphics g = Graphics.FromImage(bitmap)) { g.CopyFromScreen(System.Drawing.Point.Empty, System.Drawing.Point.Empty, bounds.Size); } string fullName = Directory.GetCurrentDirectory() + "\\" + DateTime.Now.ToString("yyyyMMddHHmmssffff") + ".jpg"; bitmap.Save(fullName, ImageFormat.Jpeg); } } } }

效果如图：

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Drawing; using System.Windows.Forms; using System.IO; using System.Drawing.Imaging;

namespace ConsoleApp346 {     class Program     {         [STAThread]         static void Main(string[] args)         {             ScreenCapture();

        }

        static void ScreenCapture()         {             Rectangle bounds = Screen.GetBounds(System.Drawing.Point.Empty);             using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))             {                 using (Graphics g = Graphics.FromImage(bitmap))                 {                     g.CopyFromScreen(System.Drawing.Point.Empty, System.Drawing.Point.Empty, bounds.Size);                 }

                using (SaveFileDialog sfd = new SaveFileDialog())                 {                     sfd.Title = "Save Pictures";                     sfd.InitialDirectory = Directory.GetCurrentDirectory();                     sfd.RestoreDirectory = true;                     sfd.Filter = "bmp files(*.bmp)|*.bmp|All Files(*.*)|*.*";                     sfd.FileName = DateTime.Now.ToString("yyyyMMddHHmmssffff") + ".jpg";                     if (sfd.ShowDialog() == DialogResult.OK)                     {                                                 bitmap.Save(sfd.FileName, ImageFormat.Jpeg);                     }                 }             }         }     } }

效果如下所示：

 1 using System;
 2 using System.Collections.Generic;  3 using System.Linq;  4 using System.Text;  5 using System.Threading.Tasks;  6 using System.Drawing;  7 using System.Windows.Forms;  8 using System.IO;  9 using System.Drawing.Imaging; 10 11 namespace ConsoleApp346 12 { 13 class Program 14  { 15  [STAThread] 16 static void Main(string[] args) 17  { 18  ScreenCapture(); 19 20  } 21 22 static void ScreenCapture() 23  { 24 Rectangle bounds = Screen.GetBounds(System.Drawing.Point.Empty); 25 using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height)) 26  { 27 using (Graphics g = Graphics.FromImage(bitmap)) 28  { 29  g.CopyFromScreen(System.Drawing.Point.Empty, System.Drawing.Point.Empty, bounds.Size); 30  } 31 32 using (SaveFileDialog sfd = new SaveFileDialog()) 33  { 34 sfd.Title = "Save Pictures"; 35 sfd.InitialDirectory = Directory.GetCurrentDirectory(); 36 sfd.RestoreDirectory = true; 37 sfd.Filter = "bmp files(*.bmp)|*.bmp|All Files(*.*)|*.*"; 38 sfd.FileName = DateTime.Now.ToString("yyyyMMddHHmmssffff") + ".jpg"; 39 if (sfd.ShowDialog() == DialogResult.OK) 40  { 41  bitmap.Save(sfd.FileName, ImageFormat.Jpeg); 42  } 43  } 44  } 45  } 46  } 47 }
