Class CsvEnumerable<T>

Namespace

ExcelReader.Core.Parser

Assembly

ExcelReader.Core.dll

Lazily projects CSV rows into T instances by binding each property to a fixed field index, for both synchronous and asynchronous enumeration.

The row model type to bind each CSV row to.

Remarks

The CSV-specialized counterpart to ExcelEnumerable<T>. Because CSV rows are dense (columns 0..n-1, no gaps) and every cell is text, each data row is parsed in a single indexed pass — no Row.Cells enumeration, no cell-descriptor re-walk, no per-cell binding search. It reuses the same compiled ColumnParser<T> delegates as the generic parser, but from the CSV type-map, where dates parse text rather than Excel serial numbers.

Methods

GetAsyncEnumerator(CancellationToken)

Returns an enumerator that iterates asynchronously through the collection.

public CsvEnumerable<T>.AsyncEnumerator GetAsyncEnumerator(CancellationToken cancellationToken = default)

Parameters

cancellationToken CancellationToken

A CancellationToken that may be used to cancel the asynchronous iteration.

Returns

CsvEnumerable<T>.AsyncEnumerator

An enumerator that can be used to iterate asynchronously through the collection.

GetEnumerator()

Returns an enumerator that iterates through the collection.

public CsvEnumerable<T>.Enumerator GetEnumerator()

Returns

CsvEnumerable<T>.Enumerator

An enumerator that can be used to iterate through the collection.
