如果打印机对话框已取消,则不打印？

Question

如果我运行此代码,并在PrintDialog上按取消,它仍会打印.如何判断使用是否取消？

PrintDocument document = new PrintDocument();
PrintDialog dialog = new PrintDialog();

dialog.ShowDialog();
document.PrinterSettings = p.PrinterSettings;
document.Print();

WebBrowser w = new WebBrowser();
w.ShowPrintDialog(); //.ShowPrintDialog returns a void, how can I deal with this?

您可以检查ShowDialog方法的结果:

if (dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
   //Print
}
