Public Function TryReadCharacterStringBytes (destination As Span(Of Byte), expectedTag As Asn1Tag, ByRef bytesWritten As Integer) As Boolean

Parameters

destination

Span<Byte>

The buffer in which to write.

expectedTag

Asn1Tag

The tag to check for before reading.

bytesWritten

Int32

On success, receives the number of bytes written to destination.

Returns

Boolean

true and advances the reader if destination had sufficient length to receive the value, otherwise false and the reader does not advance.
