如何在C＃中将字符串转换为PictureBox

Question

我有一个PictureBox类型的数组。我想填写字符串列表，然后将其转换为条形码。但我是叔叔将字符串转换为PictureBox。有什么步骤可以让它们兼容吗？

System.Windows.Forms.PictureBox[] PictureBoxArray = new PictureBox[3];
List<string> serial = new List<string>;

public void ConvertToBarCode()
{
   BarcodeLib.TYPE barcodetype1 = BarcodeLib.TYPE.CODE39;
   BarcodeLib.Barcode bar1 = new BarcodeLib.Barcode();
   bar1.IncludeLabel = true;
   PictureBoxArray[0] = serial[0]; // Want to Convert String to PictureBox
   PictureBoxArray[0].Image = bar1.Encode(barcodetype1, SerialNumberList[0]);
}

我已经用字符串填充了串行列表，现在只想转换。

你想要这样..对吧？看到这是3of9中这个字符串“S1253551”的表示和纯文本，最后是图像对吗？

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;
}

请记住，您必须安装“free of of 9”字体。

传递字符串“S1253551”并生成条形码并在底部添加纯文本，最后将其作为图像返回。
