Anda dapat membuat kode sesuatu yang sangat sederhana yang akan menghubungkan PrintScreen dan menyimpan hasil tangkapannya dalam sebuah file.
Berikut adalah sesuatu untuk mulai menangkap dan menyimpan ke file. Anda hanya perlu mengaitkan tombol "Print screen".
using System;
using System.Drawing;
using System.IO;
using System.Drawing.Imaging;
using System.Runtime.InteropServices;
public class CaptureScreen
{
static public void Main(string[] args)
{
try
{
Bitmap capture = CaptureScreen.GetDesktopImage();
string file = Path.Combine(Environment.CurrentDirectory, "screen.gif");
ImageFormat format = ImageFormat.Gif;
capture.Save(file, format);
}
catch (Exception e)
{
Console.WriteLine(e);
}
}
public static Bitmap GetDesktopImage()
{
WIN32_API.SIZE size;
IntPtr hDC = WIN32_API.GetDC(WIN32_API.GetDesktopWindow());
IntPtr hMemDC = WIN32_API.CreateCompatibleDC(hDC);
size.cx = WIN32_API.GetSystemMetrics(WIN32_API.SM_CXSCREEN);
size.cy = WIN32_API.GetSystemMetrics(WIN32_API.SM_CYSCREEN);
m_HBitmap = WIN32_API.CreateCompatibleBitmap(hDC, size.cx, size.cy);
if (m_HBitmap!=IntPtr.Zero)
{
IntPtr hOld = (IntPtr) WIN32_API.SelectObject(hMemDC, m_HBitmap);
WIN32_API.BitBlt(hMemDC, 0, 0,size.cx,size.cy, hDC, 0, 0, WIN32_API.SRCCOPY);
WIN32_API.SelectObject(hMemDC, hOld);
WIN32_API.DeleteDC(hMemDC);
WIN32_API.ReleaseDC(WIN32_API.GetDesktopWindow(), hDC);
return System.Drawing.Image.FromHbitmap(m_HBitmap);
