Question

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课程中即可？

欢迎任何想法

更新我使用了Andrei Schneider的Free Barcode API for .NET中的帖子......

 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");

然后在视图中@Model.BarcodeImage

但这会引发错误：

    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？

Answer 1

您需要将条形码生成为图像，然后照常在页面上渲染图像。看到这个免费的库：

Answer 2

@ViewBag.mostrar = "data:image/jpg;base64," +
 Convert.ToBase64String((byte[])model.BarcodeImage);

我希望比这更能帮到你
