this.Visible = false;
System.Threading.Thread.Sleep(200);
Bitmap bit = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
Graphics g = Graphics.FromImage(bit);
g.CopyFromScreen(new Point(0,0),new Point(0,0),bit.Size);
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "bmp|*.bmp|jpg|*.jpg|gif|*.gif";
if (saveFileDialog.ShowDialog() != DialogResult.Cancel)
{
bit.Save(saveFileDialog.FileName);
}
g.Dispose();
this.Visible = true;
}
截取窗体
private void button2_Click(object sender, EventArgs e)
{
Bitmap bit = new Bitmap(this.Width,this.Height);
Graphics g = Graphics.FromImage(bit);
g.CopyFromScreen(this.Location, new Point(0, 0), bit.Size);
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "bmp|*.bmp|jpg|*.jpg|gif|*.gif";
if (saveFileDialog.ShowDialog() != DialogResult.Cancel)
{
bit.Save(saveFileDialog.FileName);
}
g.Dispose();
