sending ping with specific bytes amount using c#

Question

how can i send a ping request with a specific size of bytes, the same as determining the -l when sending ping through the command line. can you give me an example?

also can i determine the amount of packets that the ping sends? like the -n on the command line.

thanks :)

You can use the System.Net.NetworkInformation.Ping class to send ICMP echo requests. It gives you complete control over the packet size and the number of packets sent:

using System.Net.NetworkInformation;

public void PingHost(string host, int packetSize, int packetCount)
{
    int timeout = 1000;  // 1 second timeout.
    byte[] packet = new byte[packetSize];
    // Initialize your packet bytes as you see fit.

    Ping pinger = new Ping();
    for (int i = 0; i < packetCount; ++i) {
        pinger.Send(host, timeout, packet);
    }
}
