Overrides Stream
This instance method writes the supplied buffer into the OracleBlob
.
Declaration
// C# public override void Write(byte[ ] buffer, int offset, int count);
Parameters
buffer
The byte array buffer
that provides the data.
offset
The 0
-based offset (in bytes) from which the buffer
is read.
count
The amount of data (in bytes) that is to be written into the OracleBlob
.
Exceptions
ObjectDisposedException
- The object is already disposed.
InvalidOperationException
- The OracleConnection
is not open or has been closed during the lifetime of the object.
ArgumentOutOfRangeException
- This exception is thrown if any of the following conditions exist:
The offset
or the count
is less than 0
.
The offset
is greater than or equal to the buffer
.Length
.
The offset
and the count
together are greater than buffer
.Length
.
Remarks
Destination offset
in the OracleBlob
can be specified by the Position
property.
Example
// C# using System; using Oracle.DataAccess.Client; using Oracle.DataAccess.Types; class WriteSample { static void Main() { string constr = "User Id=scott;Password=tiger;Data Source=oracle"; OracleConnection con = new OracleConnection(constr); con.Open(); OracleBlob blob = new OracleBlob(con); // Set the Position for the Write blob.Position = 0; // Begin ChunkWrite to improve performance // Index updates occur only once after EndChunkWrite blob.BeginChunkWrite(); // Write to the OracleBlob in 5 chunks of 2 bytes each byte[] b = new byte[2] {1, 2}; for(int index = 0; index < 5; index++) { blob.Write(b, 0, b.Length); } blob.EndChunkWrite(); byte[] chunkBuffer = blob.Value; // Prints "chunkBuffer = 1212121212" Console.Write("chunkBuffer = "); for(int index = 0; index < chunkBuffer.Length; index++) { Console.Write(chunkBuffer[index]); } Console.WriteLine(); blob.Close(); blob.Dispose(); con.Close(); con.Dispose(); } }
