CsvFieldContext Class

Definition

Namespace: DataStandardizer.File.CSV

The context for a CSV field being processed, passed to the field handler and converter delegates. It exposes the field’s identity, the surrounding line, the model, the raw value, and the active options.

.NET:

public sealed record CsvFieldContext<TModel> where TModel : class

.NET Standard:

public sealed class CsvFieldContext<TModel> where TModel : class

Remarks

On .NET 5 and later the type is a record; on .NET Standard it is a plain class. You do not construct it — its constructor and property setters are internal. The library supplies a populated instance to your CsvFieldBadValue, CsvFieldCount, CsvFieldValidate, CsvFieldConvertFromString, and CsvFieldConvertToString delegates. All properties are publicly read-only.
