Remarks

A single moving cursor (_pos) into a pooled buffer refilled/compacted via ExcelReader.Core.Reader.Internal.BufferedStreamCursor. Most fields reference the buffer directly with no copy; only fields needing unescaping materialize into the cell accumulator's value buffer. Records parse from buffered bytes only — a partially-buffered record restarts after a refill, so sync and async share one parser and async awaits once per refill, not per field.

Properties

Current

Gets the row at the enumerator's current position. Only valid after a call to MoveNext() or MoveNextAsync() has returned true.

public Row Current { get; }

Property Value

Row

Methods

MoveNext()

Advances the enumerator to the next row, reading synchronously.

public bool MoveNext()

Returns

bool

true if a row was read; false if the sheet is exhausted.

MoveNextAsync()

Advances the enumerator to the next row, reading asynchronously.

public ValueTask<bool> MoveNextAsync()

Returns

ValueTask<bool>

true if a row was read; false if the sheet is exhausted.
