C#windows app中的打印问题 - 始终打印到默认打印机

Question

我有以下代码来抛出打印机对话框,但无论我选择什么打印机,它总是打印到默认打印机.

如何为用户选择的打印机分配？(从对话窗口)

PrintDialog pdlg = new PrintDialog();

// Show the PrintDialog
if (pdlg.ShowDialog() == DialogResult.OK)
{
   PrintDocument pd = new PrintDocument();
   pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);

   // Associate PrintDocument object with the PrintDialog
   pdlg.Document = pd;

   // Print with the new PrinterSettings
   pd.Print();
}

Answer 1

在调用ShowDialog()之前,需要将PrintDocument分配给PrintDialog.
