Example

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

C++

Copy

// 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"));

Copy

// 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"));
