Question

我有一个窗口表格。我想在没有窗口外观的情况下打印表单的内容。我的意思是我想像收据一样打印，没有窗口边框。我该怎么做？

Answer 1

您可以参考MSDN示例了解如何Print to a Windows Form，将正在打印的曲面从“表单”更改为“面板控件”，这样您就可以在不使用边框的情况下进行打印。您的内容必须添加到面板而不是表单，但它将起作用。以下是MSDN示例的修改示例。

public class Form1 : Form
{
    private Panel printPanel = new Panel();
    private Button printButton = new Button();
    private PrintDocument printDocument1 = new PrintDocument();

    public Form1()
    {
        printPanel.Size = this.ClientSize;
        this.Controls.Add(printPanel);
        printButton.Text = "Print Form";
        printButton.Click += new EventHandler(printButton_Click);
        printDocument1.PrintPage += new PrintPageEventHandler(printDocument1_PrintPage);
        printPanel.Controls.Add(printButton);

    }

    void printButton_Click(object sender, EventArgs e)
    {
        CaptureScreen();
        printDocument1.Print();
    }


    Bitmap memoryImage;

    private void CaptureScreen()
    {
        Graphics myGraphics = printPanel.CreateGraphics();
        Size s = printPanel.Size; 
        memoryImage = new Bitmap(s.Width, s.Height, myGraphics);
        Graphics memoryGraphics = Graphics.FromImage(memoryImage);
        Point screenLoc = PointToScreen(printPanel.Location); // Get the location of the Panel in Screen Coordinates
        memoryGraphics.CopyFromScreen(screenLoc.X, screenLoc.Y, 0, 0, s);
    }

    private void printDocument1_PrintPage(System.Object sender,
           System.Drawing.Printing.PrintPageEventArgs e)
    {
        e.Graphics.DrawImage(memoryImage, 0, 0);
    }



    public static void Main()
    {
        Application.Run(new Form1());
    }
}

你可以通过做这样的事情得到一个空白的屏幕

this.FormBorderStyle = System.Windows.Forms.FormsBorderStyle.None;
this.ControlBox = false;
this.Text = String.Empty;
