// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Socket socket = new Chilkat.Socket();

// Connect to port 5555 of localhost.
// The string "localhost" is for testing on a single computer.
// It would typically be replaced with an IP hostname, such
// as "www.chilkatsoft.com".
bool ssl = false;
int maxWaitMillisec = 20000;
bool success = await socket.ConnectAsync("localhost",5555,ssl,maxWaitMillisec);
if (success != true) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

// Set maximum timeouts for reading an writing (in millisec)
socket.MaxReadIdleMs = 10000;
socket.MaxSendIdleMs = 10000;

// Pretend, for the sake of the example, that the
// ficticious server is going to send a "Hello World!" 
// after accepting the connection.  
// Note: Technically, the ReceiveString may not receive the
// complete string, although it's highly probable given the short
// length of the "Hello World!" message. 
// See this Chilkat blog post for more information:
// http://www.cknotes.com/?p=302
string receivedMsg = await socket.ReceiveStringAsync();
if (socket.LastMethodSuccess != true) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
success = await socket.CloseAsync(20000);

Debug.WriteLine(receivedMsg);
