Copies bytes to the buffered stream and advances the current position within the buffered stream by the number of bytes written.

public:
 override void Write(cli::array <System::Byte> ^ array, int offset, int count);
public override void Write(byte[] array, int offset, int count);
override this.Write : byte[] * int * int -> unit
Public Overrides Sub Write (array As Byte(), offset As Integer, count As Integer)

Parameters

array
Byte[]

The byte array from which to copy count bytes to the current buffered stream.

offset
Int32

The offset in the buffer at which to begin copying bytes to the current buffered stream.

count
Int32

The number of bytes to be written to the current buffered stream.

Exceptions

ArgumentException

Length of array minus offset is less than count.

ArgumentNullException

array is null.

ArgumentOutOfRangeException

offset or count is negative.

IOException

The stream is closed or null.

NotSupportedException

The stream does not support writing.

ObjectDisposedException

Methods were called after the stream was closed.

Examples

This code example is part of a larger example provided for the BufferedStream class.

// Send the data using the BufferedStream.
Console.WriteLine("Sending data using BufferedStream.");
startTime = DateTime.Now;
for(int i = 0; i < numberOfLoops; i++)
{
    bufStream.Write(dataToSend, 0, dataToSend.Length);
}
bufStream.Flush();
bufferedTime = (DateTime.Now - startTime).TotalSeconds;
Console.WriteLine("{0} bytes sent in {1} seconds.\n",
    numberOfLoops * dataToSend.Length,
    bufferedTime.ToString("F1"));

// Send the data using the BufferedStream.
printfn "Sending data using BufferedStream."
let startTime = DateTime.Now
for _ = 0 to numberOfLoops - 1 do
    bufStream.Write(dataToSend, 0, dataToSend.Length)
bufStream.Flush()
let bufferedTime = (DateTime.Now - startTime).TotalSeconds
printfn $"{numberOfLoops * dataToSend.Length} bytes sent in {bufferedTime:F1} seconds.\n"

' Send the data using the BufferedStream.
Console.WriteLine("Sending data using BufferedStream.")
startTime = DateTime.Now
For i As Integer = 1 To numberOfLoops
    bufStream.Write(dataToSend, 0, dataToSend.Length)
Next i

bufStream.Flush()
bufferedTime = DateTime.Now.Subtract(startTime).TotalSeconds
Console.WriteLine("{0} bytes sent In {1} seconds." & vbCrLf, _
    numberOfLoops * dataToSend.Length, _
    bufferedTime.ToString("F1"))
