HealthVault

Reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read.

Namespace: Microsoft.Health
Assembly: Microsoft.Health (in Microsoft.Health.dll) Version: 2.0.0.0 (1.9.2679.7415)

Syntax

C++

Copy

public override int Read(
	byte[] buffer,
	int offset,
	int count
)

Parameters

buffer: Type: array<System..::..Byte>[]()[][]
An array of bytes. When this method returns, the buffer contains the specified byte array with the values between offset and (offset + count - 1) replaced by the bytes read from the current source.

offset: Type: System..::..Int32
The zero-based byte offset in buffer at which to begin storing the data read from the current stream.

count: Type: System..::..Int32
The maximum number of bytes to be read from the current stream.

Return Value

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

Exception	Condition
System..::..NotSupportedException	If the stream does not support reading.
System..::..ArgumentNullException	buffer is null.
System..::..ArgumentException	The sum of offset and count is greater than the buffer length.
System..::..ArgumentOutOfRangeException	offset or count is negative.
System..::..ObjectDisposedException	Methods were called after the stream was closed.
Microsoft.Health..::..HealthServiceException	If there was a failure reading the data from HealthVault.
