UDP Client Problem

[Guest]

Can anyone tell my what is wrong with this snippet of code?

//Creates a UdpClient for reading incoming data.
UdpClient receivingUdpClient = new UdpClient();

//Creates an IPEndPoint to record the IP Address and port number of the sender.
// The IPEndPoint will allow you to read datagrams sent from any source.
IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Parse("192.168.1.101"), 11000);

try
{

// Blocks until a message returns on this socket from a remote host.
ERROR at this line ---------->>> Byte[] receiveBytes = receivingUdpClient.Receive(ref RemoteIpEndPoint);

string returnData = Encoding.ASCII.GetString(receiveBytes);

Console.WriteLine("This is the message you received " +

The ERROR I receive is:

System.Net.Sockets.SocketException: An invalid argument was supplied
at System.Net.Sockets.Socket.ReceiveFrom(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags, EndPoint& remoteEP)
at System.Net.Sockets.UdpClient.Receive(IPEndPoint& remoteEP)


TIA,

Does this work?

UdpClient receivingUdpClient = new UdpClient();
receivingUdpClient.Connect(new IPEndPoint(IPAddress.Parse("192.168.1.101"),
11000));
IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
Byte[] receiveBytes = receivingUdpClient.Receive(ref RemoteIpEndPoint);
string returnData = System.Text.Encoding.ASCII.GetString(receiveBytes);
receivingUdpClient.Close();

No, same problem as before

Sorry, then I don't know what the problem is.
It works great on my machine.

Hello

The problem is that you specify the UdbClient is not bound to a local end
point. You didn't specify which port and IP address (on the local computer)
the client should be listening on. Assuming that 192.168.0.101 is the ip
address of the local computer that you want to use for receiving message,
and port 11000 is the port you want to use.

UdpClient receivingUdpClient = new UdpClient(new
IPEndPoint(IPAddress.Parse("192.168.1.101"), 11000));
IPEndPoint RemoteIpEndPoint = null;
try
{
byte[] receiveBytes = receivingUdpClient.Receive(ref RemoteIpEndPoint);
string returnData = Encoding.ASCII.GetString(receiveBytes);
Console.WriteLine("This is the message you received " +


This should work,

Best regards
Sherif
