问题是这并没有捕获我的整个屏幕。它在底部和右侧缺失了大约 1/5。

如何使用 C# .NET Framework 捕获我的整个屏幕？

Answer 1

使用VirtualScreen :

int screenLeft = SystemInformation.VirtualScreen.Left;
int screenTop = SystemInformation.VirtualScreen.Top;
int screenWidth = SystemInformation.VirtualScreen.Width;
int screenHeight = SystemInformation.VirtualScreen.Height;

// Create a bitmap of the appropriate size to receive the full-screen 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);
    }

    //Save the screenshot as a Jpg image
    var uniqueFileName = "C:\\temp\\a.Jpg";
    try
    {
        bitmap.Save(uniqueFileName, ImageFormat.Jpeg);
    }
    catch (Exception ex) {
    }
 }
