Receive multiple packets in a UdpClient

Question

I'm making an app that connects to a UDP server that sends multiple packets with different byte sizes, but the problem is that my UdpClient only can receive 1 packet and I want to receive 8 packets, I have tried to make 8 byte arrays and call the client.Receive() function but still not sending the 8 packets.

Packet Sizes:

Packet1 - 1341 bytes
Packet2 - 147 bytes
Packet3 - 841 bytes
Packet4 - 841 bytes
Packet5 - 25 bytes
Packet6 - 1082 bytes
Packet7 - 1085 bytes
Packet8 - 1061 bytes

Code:

UdpClient client = new UdpClient(20777);
IPEndPoint ep = new IPEndPoint(IPAddress.Any, 0);

void UpdateData()
{
while (true)
{
// Receive data from Server
byte[] arr = client.Receive(ref ep);
// Print to console how much data has been sent
Console.WriteLine(arr.Length.ToString()); // Output: 1085 (Packet7 Size)
}
}

Well, UDP is not 'reliable' like TCP. Are you getting any ICMP back at the server? What's Wireshark/tcpdump say?

FYI, some people here review udp code too:
