【问题标题】:How to get the screen size of monitor in Windows Form application for capturing screenshots?如何在 Windows 窗体应用程序中获取监视器的屏幕大小以捕获屏幕截图?

【问题描述】:
我正在研究一种解决方案,它会定期抓取屏幕截图并以图像的形式保存。此应用程序是在 Windows 窗体中构建的。
我已经使用下面的代码来获取屏幕分辨率-:
int h = Screen.PrimaryScreen.WorkingArea.Height;
int w = Screen.PrimaryScreen.WorkingArea.Width;
这适用于分辨率为 1366 * 768 的笔记本电脑。
但是当在一个非常大的显示器上执行相同的应用程序时,图像会从右侧和底部被裁剪掉。
有没有办法在代码中处理监视器大小。

int screenWidth = SystemInformation.VirtualScreen.Width;
int screenHeight = SystemInformation.VirtualScreen.Height;
// Create a bitmap of the appropriate size to receive the screenshot.
using (Bitmap bitmap = new Bitmap(screenWidth, screenHeight))
{
// Draw the screenshot into our bitmap.
using (Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(screenLeft, screenTop, 0, 0, bitmap.Size);
}
var uniqueFileName = Path.Combine(System.IO.Path.GetTempPath(), Path.GetRandomFileName().Replace(".", string.Empty) + ".jpeg");
try

bitmap.Save(uniqueFileName, ImageFormat.Jpeg);
}
catch (Exception ex)

return uniqueFileName;
