Where does BarcodeResults live in the IronBarcode API?

BarcodeResults is a class in the IronBarCode namespace, shipped in IronBarCode.dll, deriving from List of BarcodeResult. BarcodeReader.Read and ReadPdf return one, holding every detected code.

How do I get all decoded values from a barcode read in C#?

Read the Values property of the BarcodeResults, which returns a string array of every decoded value. To inspect each code's type and position instead, iterate the collection and read each BarcodeResult.

Class BarcodeResults

Collection of barcode reading results.

Inheritance

System.Object

BarcodeResults

Namespace: IronBarCode

Assembly: IronBarCode.dll

Syntax

public class BarcodeResults : List<BarcodeResult>

BarcodeResults is the collection a BarcodeReader.Read call hands back, holding every BarcodeResult found in a source. It is a List<BarcodeResult>, so a developer iterates it with foreach and uses the usual list members directly, while a few extra members make whole-batch work easier. This is what a developer receives from any read, whether the image held one code or several.

Because it derives from List<BarcodeResult>, the collection supports indexing, Count, and iteration out of the box, so reading each decoded Value is a plain loop. On top of that, Values returns a string[] of every decoded value in one step, handy when only the text is needed and the per-code geometry is not. FilterImages exposes the processed images IronBarcode worked from as an AnyBitmap[], and ExportFilterImagesToDisk writes those images to a folder, which is useful for inspecting why a difficult scan did or did not detect a code. Iterate the collection for full per-code detail, or read Values when a flat list of decoded strings is all a job needs.

BarcodeResults results = BarcodeReader.Read("page.png");
string[] values = results.Values;

The read multiple barcodes how-to iterates a multi-code result, and the read barcodes from images how-to consumes the collection from a single read.

Methods

ExportFilterImagesToDisk(String)

Exports all intermediate images generated during the filtering process to disk.

Declaration

public void ExportFilterImagesToDisk(string filename)

Parameters

Type	Name	Description
System.String	filename	Filename to export to disk.

Remarks

All image files will contain "-i" appended to the end of the filename before the extension, where "i" represents the index of the applied filter.

CacheAtEachIteration of ImageFilterCollection in BarcodeReaderOptions must be set to true for filtered images to be generated. If BarcodeReaderOptions is not passed in, they are generated by default.

FilterImages()

Returns all intermediate images generated during the filtering process.

Declaration

public AnyBitmap[] FilterImages()

Returns

Type	Description
IronSoftware.Drawing.AnyBitmap[]

Remarks

CacheAtEachIteration of ImageFilterCollection in BarcodeReaderOptions must be set to true for filtered images to be generated. If BarcodeReaderOptions is not passed in, they are generated by default.

Values()

Returns all values of the BarcodeResult collection.

Declaration

public string[] Values()

Returns

Type	Description
System.String[]
