我想在打印文档之前显示打印对话框,因此用户可以在打印前选择其他打印机.打印代码是:
private void button1_Click(object sender,EventArgs e) { try { PrintDocument pd = new PrintDocument(); pd.PrintPage += new PrintPageEventHandler(PrintImage); pd.Print(); } catch (Exception ex) { MessageBox.Show(ex.Message,ToString()); } } void PrintImage(object o,PrintPageEventArgs e) { int x = SystemInformation.WorkingArea.X; int y = SystemInformation.WorkingArea.Y; int width = this.Width; int height = this.Height; Rectangle bounds = new Rectangle(x,y,width,height); Bitmap img = new Bitmap(width,height); this.DrawToBitmap(img,bounds); Point p = new Point(100,100); e.Graphics.DrawImage(img,p); }
这段代码能够打印当前表格吗?
解决方法
你必须使用PrintDialog
PrintDocument pd = new PrintDocument(); pd.PrintPage += new PrintPageEventHandler(PrintPage); PrintDialog pdi = new PrintDialog(); pdi.Document = pd; if (pdi.ShowDialog() == DialogResult.OK) { pd.Print(); } else { MessageBox.Show("Print Cancelled"); }

在64位Windows和某些版本的.NET上,您可能必须设置pdi.UseExDialog = true;用于显示对话框窗口.
