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.
