显示打印对话框打印前

问题描述

我要打印文档前显示打印对话框，使用户可以在打印前选择另一台打印机。在code打印是：

I want to show the print dialog box before printing the document, so the user can choose another printer before printing. The code for printing is:

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);
        }

将在code能打印当前的形式？

will this code be able to print the current form?

推荐答案

您必须使用 PrintDialog类

 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");
 }

编辑（从评论）

在 64位 Windows和.NET与某些版本的，你可能必须设置 pdi.UseExDialog = TRUE ;该对话框窗口出现。

On 64-bit Windows and with some versions of .NET you may have to set pdi.UseExDialog = true; for the dialog window to appear.
