Where does OcrPassportResult live in the IronOCR API?

OcrPassportResult is a class in the IronOcr namespace, shipped in IronOcr.dll. It derives from System.Object and implements IOcrResult, and IronTesseract.ReadPassport returns it.

How do you read passport fields in C#?

Call ReadPassport on an IronTesseract to get an OcrPassportResult, then read its PassportInfo property for the decoded fields. Text holds the raw recognized characters and Confidence reports the overall certainty score.

Class OcrPassportResult

Result from ReadPassport(OcrInputBase)

Give an access to: Text, Confidence, and PassportInfo.

Inheritance

System.Object

OcrPassportResult

Implements

IronSoftware.Abstractions.Ocr.IOcrResult

Namespace: IronOcr

Assembly: IronOcr.dll

Syntax

public class OcrPassportResult : Object

When a passport read finishes in C#, OcrPassportResult is the object that carries the outcome. IronTesseract.ReadPassport returns one, bundling the raw recognized text, an overall confidence score, and the structured passport fields decoded from the document. It pairs with PassportInfo, which holds the typed fields, while this result wraps that data alongside the plain Text so a workflow can pick whichever view it needs.

The members are read directly off the returned object. PassportInfo is the structured payload, the MRZ and VIZ fields such as surname, passport number, nationality, and dates, ready as typed properties rather than a raw string to parse. Text exposes the recognized text the engine produced, and Confidence reports certainty as a score so low-quality scans can be flagged or retried. For most workflows, read PassportInfo for the parsed fields and check Confidence before relying on them.

The read passport how-to covers the full extraction, and the passport reading example shows the result in code.

Properties

Confidence

OCR statistical accuracy confidence as an average of every character.

1 = 100%, 0 = 0%.

Declaration

public double Confidence { get; }

Property Value

Type	Description
System.Double

PassportInfo

Passport informations decoded from MRZ and VIZ.

MRZ fields: Document type, Surname, Given names, Passport No., Country / IssuingCountryCode, Nationality / NationalityCode, Date of birth, Gender, Date of expiry, Personal number.

VIZ fields (best-effort): Date of issue.

Raw codes: Use IssuingCountryCode / NationalityCode for custom localization instead of the English-mapped Country / Nationality names.

Declaration

public PassportInfo PassportInfo { get; }

Property Value

Type	Description
PassportInfo

Text

All Ocr texts from OcrInput.

Declaration

public string Text { get; }

Property Value

Type	Description
System.String
