如何在视图中生成条形码
本文关键字:条形码 视图 | 更新日期: 2023-09-27 17:57:56
条形码是从控制器传递并显示在视图上的字符串:
@shelfEdge.Barcode
如何以条形码格式显示,只需下载条形码字体并将其添加到类中即可?
任何想法欢迎
更新我在免费条形码API中使用过这篇文章。NET。。。
BarcodeLib.Barcode barcode = new BarcodeLib.Barcode()
{
IncludeLabel = true,
Alignment = AlignmentPositions.CENTER,
Width = 300,
Height = 100,
RotateFlipType = RotateFlipType.RotateNoneFlipNone,
BackColor = Color.White,
ForeColor = Color.Black,
};
model.BarcodeImage = barcode.Encode(TYPE.CODE128B, "123456789");
则在视图CCD_ 1 中
但这抛出了errro:
Compiler Error Message: CS0012: The type 'System.Drawing.Image' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
Source Error:
Line 54: </td>
Line 55: <td width="30%">
Line 56: @Model.BarcodeImage
Line 57: </td>
Line 58: </tr>
我在项目中引用了system.drawing??
您需要将条形码生成为图像,然后像往常一样在页面上呈现图像。查看此免费库:
http://barcoderender.codeplex.com/
@ViewBag.mostrar = "data:image/jpg;base64," +
Convert.ToBase64String((byte[])model.BarcodeImage);
我希望这能帮助你
