How to check if byte[] contains only zeros?

Question

How can I check if a byte[] contains only 0's? I do not want to send the array over the network if it only contains zeroes:

byte[] bytesToBeSend = e.GetAudioSamples;

// Send test data to the remote device.
Send(client, bytesToBeSend);

Answer 1

Insert this test before your Send request and use an if test:

bool hasAllZeroes = bytesToBeSend.All(singleByte => singleByte == 0);

if (!hasAllZeroes) {
    Send(client, bytesToBeSend);
}

Make sure that you've included LINQ:

using System.Linq;
