我有一个像这样的gridView,我使用字体Free 3 of 9来显示:

我希望像这样打印出来:

我必须获取Column值并将其转换为Bitmap并在页面上打印。我不知道该怎么做。如何将列值转换为图像中显示的格式,然后如何在单个页面上打印每行BarCode? enter image description here

How to Add the values of List<string> into the List<PictureBox> after encoding it to Barcode in c#

    public Image stringToImage(string inputString)
    { 
        string text = inputString.Trim();

        Bitmap bmp = new Bitmap(1, 1);

        //Set the font style of output image
        Font font = new Font("Free 3 of 9", 25, FontStyle.Regular, GraphicsUnit.Pixel);
        Font font2 = new Font("Arial", 15, FontStyle.Regular, GraphicsUnit.Pixel);

        Graphics graphics = Graphics.FromImage(bmp);

        int width = (int)graphics.MeasureString(text, font).Width;
        int height = (int)graphics.MeasureString(text, font).Height;

        int height2 = (int)graphics.MeasureString(text, font2).Height;

        bmp = new Bitmap(bmp, new Size(width, height+height2));
        graphics = Graphics.FromImage(bmp);



        //Specify the background color of the image
        graphics.Clear(Color.Cyan);
        graphics.SmoothingMode = SmoothingMode.AntiAlias;
        graphics.TextRenderingHint = TextRenderingHint.AntiAlias;



        //Specify the text, font, Text Color, X position and Y position of the image
        graphics.DrawString(text, font, new SolidBrush(Color.Black), 0, 0);
        graphics.DrawString(text, font2, new SolidBrush(Color.Black), 0, height);

        graphics.Flush();
        graphics.Dispose();

        //if you want to save the image  uncomment the below line.
        //bmp.Save(@"d:\myimage.jpg", ImageFormat.Jpeg);

        return bmp;

您必须安装字体“free 3 of 9”
