Stream.ReadExactly Method

Definition

Namespace:

System.IO

Assembly:

System.Runtime.dll

Overloads

ReadExactly(Span<Byte>)	Reads bytes from the current stream and advances the position within the stream until the buffer is filled.
ReadExactly(Byte[], Int32, Int32)	Reads count number of bytes from the current stream and advances the position within the stream.

ReadExactly(Span<Byte>)

Source:

Stream.cs

Reads bytes from the current stream and advances the position within the stream until the buffer is filled.

public:
 void ReadExactly(Span<System::Byte> buffer);

public void ReadExactly (Span<byte> buffer);

member this.ReadExactly : Span<byte> -> unit

Public Sub ReadExactly (buffer As Span(Of Byte))

Parameters

buffer

Span<Byte>

A region of memory. When this method returns, the contents of this region are replaced by the bytes read from the current stream.

Exceptions

EndOfStreamException

The end of the stream is reached before filling the buffer.

Remarks

When buffer is empty, this read operation will be completed without waiting for available data in the stream.

ReadExactly(Byte[], Int32, Int32)

Source:

Stream.cs

Reads count number of bytes from the current stream and advances the position within the stream.

public:
 void ReadExactly(cli::array <System::Byte> ^ buffer, int offset, int count);

public void ReadExactly (byte[] buffer, int offset, int count);

member this.ReadExactly : byte[] * int * int -> unit

Public Sub ReadExactly (buffer As Byte(), offset As Integer, count As Integer)

Parameters

buffer

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 stream.

offset

Int32

The byte offset in buffer at which to begin storing the data read from the current stream.

count

Int32

The number of bytes to be read from the current stream.

Exceptions

ArgumentNullException

buffer is null.

ArgumentOutOfRangeException

offset is outside the bounds of buffer.

-or-

count is negative.

-or-

The range specified by the combination of offset and count exceeds the length of buffer.

EndOfStreamException

The end of the stream is reached before reading count number of bytes.

Remarks

When count is 0 (zero), this read operation will be completed without waiting for available data in the stream.
