Question

我有一个c＃程序，该程序调用一项服务，该服务将从Medicare获得患者的保险状态。（由其他人写的服务）。我正在获取数据并按我的意愿显示它。有人告诉我要添加一个打印选项，但是在运行时这个消息有一个例外：

“PrintTicket提供程序无法将DEVMODE转换为PrintTicket。Win32错误：参数不正确。”

以下是打印部分的代码：也许您可以看到导致此错误的错误。

        }

        private void btnPrint_Click(object sender, RoutedEventArgs e)
        {
            Print();
        }

        private void Print()
        {
            PrintDialog PrintDialog = new PrintDialog();
            Nullable<Boolean> printClicked = PrintDialog.ShowDialog();

            if (printClicked == true)
            {
                VisualBrush VisualBrush = new VisualBrush(txtResult);
                VisualBrush.Stretch = Stretch.Uniform;
                VisualBrush.ViewboxUnits = BrushMappingMode.Absolute;
                VisualBrush.Viewbox = new Rect(5, 5, 700, 700);

                Rectangle rect = new Rectangle();
                rect.Fill = VisualBrush;
                rect.Arrange(new Rect(new Point(50, 50), new Point(900, 900) /*pageAreaSize*/));

                PrintDialog.PrintVisual(rect, Title);
            }

        }



    }
}
