Namespace: MimeKit.IO
Assembly: MimeKit (in MimeKit.dll) Version: 4.7.1
Syntax
C#
public override Task<int> ReadAsync(
	byte[] buffer,
	int offset,
	int count,
	CancellationToken cancellationToken
)

Parameters

buffer  Byte

offset  Int32
The offset into the buffer to start reading data.
count  Int32
The number of bytes to read.
cancellationToken  CancellationToken

Return Value

TaskInt32
The total number of bytes read into the buffer. This can be less than the number of bytes requested if that many bytes are not currently available, or zero (0) if the end of the stream has been reached.
Exceptions
ExceptionCondition
