复制代码 代码如下:

//截取全屏图象

private void btnFullScreen_Click(object sender, EventArgs e)

{

//创建图象，保存将来截取的图象

Bitmap image = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);

Graphics imgGraphics = Graphics.FromImage(image);

//设置截屏区域

imgGraphics.CopyFromScreen(0, 0, 0, 0, new Size(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height));

//保存

SaveImage(image);

}

//保存图象文件

private void SaveImage(Image image)

{

if (saveFileDialog.ShowDialog(this) == DialogResult.OK)

{

string fileName = saveFileDialog.FileName;

string extension = Path.GetExtension(fileName);

if (extension == ".jpg")

{

image.Save(fileName, ImageFormat.Jpeg);

}

else

{

image.Save(fileName, ImageFormat.Bmp);

}

}

}
