在C#中打印Windows窗体内容 [英] Print Windows Form content in C#

问题描述

我有一个Windows表单，其中包含图片&该图像上的一些文本框.在将这些文本框和该图像一起填充后，我需要打印内容.我使用了下面的代码，但是它只打印图像，而不打印文本框中的值.

I have a windows form which contains an image & some textboxes on that image. I need to print contents after I fill those textboxes along with that image. I''ve used below code, but it only prints the image, not the values in textboxes.

private void pictureBox1_DoubleClick(object sender, EventArgs e)
       {
           PrintDocument pd = new PrintDocument();
           pd.PrintPage += new PrintPageEventHandler(PrintImage);
           pd.Print();

       }


private void PrintImage(object o, PrintPageEventArgs e)
        {
            int x = SystemInformation.WorkingArea.X;
            int y = SystemInformation.WorkingArea.Y;
            int width = this.Width;
            int height = this.Height;

            Rectangle bounds = new Rectangle(x, y, width, height);

            Bitmap img = new Bitmap(width, height);

            this.DrawToBitmap(img, bounds);
            Point p = new Point(100, 100);
            e.Graphics.DrawImage(img, p);
        }

推荐答案

然后，您需要扩展PrintImage方法，使其包含以下内容:

Then you need to expand the PrintImage method to include something along the line of:

this.DrawToBitmap(img, bounds);
Point p = new Point(100, 100);
e.Graphics.DrawImage(img, p);
// Now add a string...
e.Graphics.DrawString("Hello World!", new Font("Arial", 16), Brushes.Black, new PointF(100.0F, 100.0F));
