一、WPF 打印操作之PrintDialog
在WPF 中可以通过PrintDialog 类方便的实现应用程序打印功能。
PrintDialog可以直接打印Wpf控件或者页面,将呈现结果使用Windows系统默认打印机,执行打印。
PrintDialog dialog = new PrintDialog(); //显示打印框,选择份数和打印机 if (dialog.ShowDialog() == true) { // dialog.PrintVisual(printArea, "Print Test"); dialog.PrintVisual(richText, "测试"); } //直接打印 // dialog.PrintVisual(richText, "测试");
