Overrides Stream

This instance method reads a specified amount of bytes from the current instance and populates the byte array buffer.

Declaration

// C#
public override int Read(byte [] buffer, int offset, int count);

Parameters

• buffer

  The byte array buffer that is populated.

• offset

  The offset (in bytes) at which the buffer is populated.

• count

  The amount of bytes to be read.

Return Value

The number of bytes read from the CLOB.

Exceptions

ObjectDisposedException - The object is already disposed.

InvalidOperationException - The OracleConnection is not open or has been closed during the lifetime of the object.

Remarks

Both offset and count must be even numbers for CLOB and NCLOB because every two bytes represent a Unicode character.

The LOB data is read starting from the position specified by the Position property, which must also be an even number.

OracleClob is free to return fewer bytes than requested, even if the end of the stream has not been reached.
