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);
}
}
}
