BarCode Reader SDK使用教程：如何从图像中读取条码
我们知道很多语言都可以在windows平台上读取条码，今天将分享在BarCode Reader SDK中如何用VB.NET或者C#来读取图像中的条码。
这段代码演示了如何从图像中读取条码及打印到输出控制台。
Visual Basic .NET:
Imports System.IO
Imports Bytescout.BarCodeReader ' requiring to install evaluation or full version of Barcode Reader SDK
<em>Module <font class="Apple-style-span" color="#000000"><span data-scayt_word="Module1" data-scayt>Module1</span></font></em>
Sub Main()
Dim pat As String = "InputPhoto.jpg"
Console.WriteLine("Reading barcode(s) from image {0}", Path.GetFullPath(pat))
Dim <span data-scayt_word="bc" data-scayt>bc</span> As New Reader()
bc.TypeToFind = SymbologyFilter.FindAll
Dim barcodes As <span data-scayt_word="FoundBarcode" data-scayt>FoundBarcode</span>() = bc.ReadFrom(pat)
Dim i As Integer
For i = 0 To barcodes.Length - 1
Console.WriteLine("Found barcode with type '{0}' and value '{1}'", barcodes(i).Type, barcodes(i).Value)
Next
Console.WriteLine("Press any key to exit..")
Console.ReadKey()
End Sub
End Module
C#
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using Bytescout.BarCodeReader; // requires to have evaluation or full version of Barcode Reader SDK installed
<span data-scayt_word="namespace" data-scayt>SimpleTestSharp</span>
{
class Program
{
<span data-scayt_word="const" data-scayt;
static void Main(string[] <span data-scayt_word="args" data-scayt>args</span>)
{
Console.WriteLine("Reading barcode(s) from image {0}", Path.GetFullPath(path));
Reader <span data-scayt_word="bc" data-scayt>bc</span> = new Reader();
<span data-scayt_word="FoundBarcode" data-scayt>FoundBarcode</span>[] barcodes = bc.ReadFrom(path);
<span data-scayt_word="foreach" data-scayt>FoundBarcode</span> barcode in barcodes)
Console.WriteLine("Found barcode with type '{0}' and value '{1}'", barcode.Type, barcode.Value);
Console.WriteLine("Press any key to exit..");
Console.ReadKey();
}
}
}
