Question

我打印的面板基本上是一个注册表单，包含3个小面板，但它只打印一个空白页...我尝试了很多次但没有解决方案。

PrintDialog myPrintDialog = new PrintDialog();
System.Drawing.Bitmap memoryImage = new System.Drawing.Bitmap(panel_stdadmcard.Width, panel_stdadmcard.Height);
panel_stdadmcard.DrawToBitmap(memoryImage, panel_stdadmcard.ClientRectangle);
PrintDocument printDocument1 = new PrintDocument();
if (myPrintDialog.ShowDialog() == DialogResult.OK)
{
    System.Drawing.Printing.PrinterSettings values;
    values = myPrintDialog.PrinterSettings;
    myPrintDialog.Document = printDocument1;
    printDocument1.PrintController = new StandardPrintController();
    printDocument1.Print();
}
printDocument1.Dispose();

Answer 1

您将面板绘制为位图，但如果此代码完成，则永远不会使用它。您应该实现printDocument的PrintPage-Event。你应该使用DrawImage绘制图像。

Answer 2

将panel_stdadmcard.ClientRectangle更改为new Rectangle(0, 0, panel_stdadmcard.Width, panel_stdadmcard.Height)

在c＃中打印面板
