Show Print Dialog before printing
提问by user2257581
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:
我想在打印文档之前显示打印对话框，以便用户可以在打印前选择另一台打印机。打印代码为：
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);
}
will this code be able to print the current form?
这段代码能打印当前的表格吗？

You have to use PrintDialog
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");
}

On 64-bitWindows and with some versions of .NET you may have to set pdi.UseExDialog = true; for the dialog window to appear.
在64-bitWindows 和某些版本的 .NET 上，您可能需要设置pdi.UseExDialog = true; 出现对话框窗口。

For the sake of completeness, the code should include a using directive
为了完整起见，代码应该包含一个 using 指令
using System.Drawing.Printing;
for further reference please goto PrintDocument Class
如需进一步参考，请转到 PrintDocument 类
