C＃中以特定区域的截图 [英] c# Take a screenshot of specific area

问题描述

我知道有很多这样的问题，但没有他们的答案都为我工作
或者只是我不能这样做正确，反正如果可能的话，请给我一个简单的code！

我知道绿点的位置，我想构建基于此位置的矩形。

例如：

和最重要的是如何利用这个区域的屏幕截图？

我不知道如何改变这种code为我的情况下工作。

 私人位图截图（）
    {
        位图bmpScreenshot =新位图（Screen.PrimaryScreen.Bounds.Width，Screen.PrimaryScreen.Bounds.Height）;        图形G = Graphics.FromImage（bmpScreenshot）;        g.CopyFromScreen（0，0，0，0，Screen.PrimaryScreen.Bounds.Size）;        返回bmpScreenshot;
    }
 

解决方案

合并在MSDN上并您的问题文档：

  g.CopyFromScreen（center.X  -  36 center.Y  -  30，0，0，新的大小（36 * 2，30 * 2））;
 

I know there are many questions like this but none of their answers are working for me or just I can't do it correctly, anyway if it's possible please give me a simple code!

I know the location of the green dot and I want to construct a rectangle based on this location.

Example:

And most important how to take a screenshot of this area?

I don't know how to change this code to work for my case.

private Bitmap Screenshot()
    {
        Bitmap bmpScreenshot = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);

        Graphics g = Graphics.FromImage(bmpScreenshot);

        g.CopyFromScreen(0, 0, 0, 0, Screen.PrimaryScreen.Bounds.Size);

        return bmpScreenshot;
    }

解决方案

Merging the documentation on MSDN and your problem:

g.CopyFromScreen(center.X - 36, center.Y - 30, 0, 0, new Size(36 * 2, 30 * 2));
