)

Parameters

array

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

offset

count

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

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.
Console.WriteLine("Sending data using BufferedStream.");
startTime = DateTime.get_Now();
for(int i=0;i < numberOfLoops;i++) {
    bufStream.Write(dataToSend, 0, dataToSend.length);
}        
bufStream.Flush();
bufferedTime = 
    ((DateTime.get_Now()).Subtract(startTime)).get_TotalSeconds();
Console.WriteLine("{0} bytes sent in {1} seconds.\n",
    System.Convert.ToString (numberOfLoops * dataToSend.length),
    ((System.Double)bufferedTime).ToString("F1"));
