本文概述
如果你正在使用C#, 并且需要生成一维条形码, 你可能会知道没有很多开源条形码渲染库, 这就是为什么条形码库是在C#中实现这一目标的最著名的库之一, Brad Barnhill创建的库已根据Apache许可发布, 因此它符合许多项目的大多数法律要求。
在本教程中, 我们将向你展示如何使用C#中的条码库生成不同类型的条码。
1.安装Barcodelib
要在Visual Studio中的项目上安装此软件包, 请转到解决方案资源管理器, 然后右键单击你的项目。从下拉列表中选择管理NuGet软件包选项:
在管理器中, 转到浏览选项卡并搜索条形码库包:
选择Brad Barnhill的第一个软件包并将其安装在你的项目中。安装完成后, 你将可以使用该库在代码上创建条形码图像。有关此库的更多信息, 请访问Github上的官方存储库。在项目中安装库之后, 你将能够导入条形码库名称空间和.NET的图像类:
// Barcodelib namespace
using BarcodeLib;
// .net required namespaces
using System.Drawing;
using System.Drawing.Imaging;
using Color = System.Drawing.Color;
2.生成条形码图像
理解如何使用C#中的此库生成条形码的最佳方法基本上是通过示例:
UPC-A
// Create an instance of the API
Barcode barcodeAPI = new Barcode();
// Define basic settings of the image
int imageWidth = 290;
int imageHeight = 120;
Color foreColor = Color.Black;
Color backColor = Color.Transparent;
string data = "038000356216";
// Generate the barcode with your settings
Image barcodeImage = barcodeAPI.Encode(TYPE.UPCA, data, foreColor, backColor, imageWidth, imageHeight);
// Store image in some path with the desired format
barcodeImage.Save(@"C:\Users\sdkca\Desktop\upca_example.png", ImageFormat.Png);
代码128
// Create an instance of the API
Barcode barcodeAPI = new Barcode();
// Define basic settings of the image
int imageWidth = 290;
int imageHeight = 120;
Color foreColor = Color.Black;
Color backColor = Color.Transparent;
string data = "ABC-abc-1234";
// Generate the barcode with your settings
Image barcodeImage = barcodeAPI.Encode(TYPE.CODE128, data, foreColor, backColor, imageWidth, imageHeight);
// Store image in some path with the desired format
barcodeImage.Save(@"C:\Users\sdkca\Desktop\code128_example.png", ImageFormat.Png);
代码11
// Create an instance of the API
Barcode barcodeAPI = new Barcode();
// Define basic settings of the image
int imageWidth = 290;
int imageHeight = 120;
Color foreColor = Color.Black;
Color backColor = Color.Transparent;
string data = "0123-4567";
// Generate the barcode with your settings
Image barcodeImage = barcodeAPI.Encode(TYPE.CODE11, data, foreColor, backColor, imageWidth, imageHeight);
// Store image in some path with the desired format
barcodeImage.Save(@"C:\Users\sdkca\Desktop\code11_example.png", ImageFormat.Png);

// Create an instance of the API

// Define basic settings of the image
int imageWidth = 290;
int imageHeight = 120;
Color foreColor = Color.Black;
Color backColor = Color.Transparent;
string data = "9781234567897";
// Generate the barcode with your settings
Image barcodeImage = barcodeAPI.Encode(TYPE.ISBN, data, foreColor, backColor, imageWidth, imageHeight);
// Store image in some path with the desired format
barcodeImage.Save(@"C:\Users\sdkca\Desktop\isbn_example.png", ImageFormat.Png);
ITF14
// Create an instance of the API
Barcode barcodeAPI = new Barcode();
// Define basic settings of the image
int imageWidth = 290;
int imageHeight = 120;
Color foreColor = Color.Black;
Color backColor = Color.Transparent;
string data = "17350053850252";
// Generate the barcode with your settings
Image barcodeImage = barcodeAPI.Encode(TYPE.ITF14, data, foreColor, backColor, imageWidth, imageHeight);
// Store image in some path with the desired format
barcodeImage.Save(@"C:\Users\sdkca\Desktop\itf14_example.png", ImageFormat.Png);
EAN13
// Create an instance of the API
Barcode barcodeAPI = new Barcode();
// Define basic settings of the image
int imageWidth = 290;
int imageHeight = 120;
Color foreColor = Color.Black;
Color backColor = Color.Transparent;
string data = "978020137962";
// Generate the barcode with your settings
Image barcodeImage = barcodeAPI.Encode(TYPE.EAN13, data, foreColor, backColor, imageWidth, imageHeight);
// Store image in some path with the desired format
barcodeImage.Save(@"C:\Users\sdkca\Desktop\ean13_example.png", ImageFormat.Png);
