Install-Package System.Drawing.Common -Version 7.0.0
Take screenshot and save to file
using System;
using System.Drawing;
using System.Windows.Forms;
namespace ScreenshotExample
{
class Program
{
static void Main(string[] args)
{
// Get the bounds of the screen
Rectangle bounds = Screen.PrimaryScreen.Bounds;
// Create a bitmap object to store the screenshot
using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
// Create a graphics object from the bitmap
using (Graphics g = Graphics.FromImage(bitmap))
{
// Capture the screen
g.CopyFromScreen(new Point(bounds.Left, bounds.Top), Point.Empty, bounds.Size);
}
// Save the screenshot as a PNG file
bitmap.Save("screenshot.png");
}
Console.WriteLine("Screenshot saved as screenshot.png");
}
}
}
Take screenshot and save to memory
using System;
using System.Drawing;
using System.IO;
using System.Windows.Forms;
namespace ScreenshotToMemory
{
class Program
{
static void Main(string[] args)
{
// Get the bounds of the screen
Rectangle bounds = Screen.PrimaryScreen.Bounds;
// Create a bitmap object to store the screenshot
using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
// Create a graphics object from the bitmap
using (Graphics g = Graphics.FromImage(bitmap))
{
// Capture the screen
g.CopyFromScreen(new Point(bounds.Left, bounds.Top), Point.Empty, bounds.Size);
}
// Store the screenshot in memory using MemoryStream
using (MemoryStream memoryStream = new MemoryStream())
{
bitmap.Save(memoryStream, System.Drawing.Imaging.ImageFormat.Png);
// Convert the MemoryStream to byte array
byte[] screenshotBytes = memoryStream.ToArray();
// Now the screenshot is stored in screenshotBytes, you can use it as needed
// For demonstration, let's output the length of the byte array
Console.WriteLine($"Screenshot captured. Byte array length: {screenshotBytes.Length}");
}
}
}
}
