You could try to save the image using this approach
您可以尝试使用这种方法保存图像
SaveFileDialog dialog = new SaveFileDialog();
if (dialog.ShowDialog() == DialogResult.OK)
{
int width = Convert.ToInt32(drawImage.Width);
int height = Convert.ToInt32(drawImage.Height);
Bitmap bmp = new Bitmap(width,height);
drawImage.DrawToBitmap(bmp, new Rectangle(0, 0, width, height);
bmp.Save(dialog.FileName, ImageFormat.Jpeg);
}

If you are drawing on the Graphics of the Control than you should do something draw on the Bitmap everything you are drawing on the canvas, but have in mind that Bitmap needs to be the exact size of the control you are drawing on:
如果您在控件的图形上绘制，那么您应该在位图上绘制您在画布上绘制的所有内容，但请记住，位图需要与您正在绘制的控件的确切大小相同：
Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width,myControl.ClientRectangle.Height);
Graphics gBmp = Graphics.FromImage(bmp);
gBmp.DrawEverything(); //this is your code for drawing
gBmp.Dispose();
bmp.Save("image.png", ImageFormat.Png);
Or you can use a DrawToBitmapmethod of the Control. Something like this:
或者你可以使用DrawToBitmapControl 的一个方法。像这样的东西：
Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width, myControl.ClientRectangle.Height);
myControl.DrawToBitmap(bmp,new Rectangle(0,0,bmp.Width,bmp.Height));
bmp.Save("image.png", ImageFormat.Png);

You can save image , save the file in your current directory application and move the file to any directory .
您可以保存图像，将文件保存在当前目录应用程序中并将文件移动到任何目录。
Bitmap btm = new Bitmap(image.width,image.height);
Image img = btm;
img.Save(@"img_" + x + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
FileInfo img__ = new FileInfo(@"img_" + x + ".jpg");
img__.MoveTo("myVideo\img_" + x + ".jpg");
