member this.Read : int64 * byte[] * int * int -> int64

Public Function Read (offset As Long, buffer As Byte(), offsetInBuffer As Integer, count As Integer) As Long

Parameters

offset: Int64

An Int64 long value offset into the value that is contained in the SqlBytes instance.

buffer: Byte[]

The byte array buffer to copy into.

offsetInBuffer: Int32

An Int32 integer offset into the buffer to start copying into.

count: Int32

An Int32 integer representing the number of bytes to copy.

Returns

Int64

An Int64 long value representing the number of copied bytes.

Remarks

If an attempt is made to read beyond MaxLength, an exception is thrown.

If count specifies more bytes to be copied than are available from the offset to the end of the value, only the available bytes are copied.

An exception is thrown if the destination buffer is a null reference.

An exception is thrown if the destination buffer cannot receive as many characters as requested.
