System.Net.Sockets.SocketException
Hi,
I'm writing a set of class libs for
.NET/Mono,
except for the UTF7 Encoding in my other post,
it should work fine.
And it does on .NET, but not on
Mono.
I don't know where to start, but I'll try to
explain.
First of all I have a Base Class which amongst
other members has the following function
private void
ExecuteQuery()
{
UdpClient client = new
UdpClient();
//Connect to the server and send the query
data
try
{
client.Connect(ip,port);
client.Send(data,data.Length);
}
catch
{
client.Close();
throw
new Exceptions.InvalidHostException("Unknown host: " +
ip);
}
//Listen for a response -
This is the client side
IPEndPoint serverIPEndPoint =
new
IPEndPoint(IPAddress.Any,0);
//Receive
the
response
try
{
queryResponse
= client.Receive(ref
serverIPEndPoint);
}
catch
(Exception e)
{
throw new
Exceptions.ConnectionRefusedException("The connection was refused by the
remote host: " + ip + ":" + port.ToString() + "\n" +
e.Message,e);
}
finally
{
client.Close();
}
}
As you can see it sends a n array of bytes to
the server and receives some in return.
Then I have a derived class which has 2
important functions:
public string
RequestStatus()
{
//Create the byte[]
array to send
byte[] query =
{0xFF,0xFF,0xFF,0xFF,0x67,0x65,0x74,0x73,0x74,0x61,0x74,0x75,0x73,0xA};
//Create
a new separator
char separator =
Convert.ToChar(10);
//A statusRequest consists of
both rules and players separated by char(10)
string[]
response =
this.QueryToString(query).Split(separator);
//Get
the rules and players
string rules =
this.RulesToXml(response[0]);
string players =
this.PlayersToXml(response);
return
this.CreateXmlBody("Quake3","statusRequest",string.Concat(rules,players));
}
And
public string
RequestInfo()
{
//Create the byte[]
array to send
byte[] query =
{0xFF,0xFF,0xFF,0xFF,0x67,0x65,0x74,0x69,0x6E,0x66,0x6F,0xA};
//Query
the server and get the response in a string
string
response =
this.QueryToString(query);
//Create
the default xml body and put the rules in it
string
returnValue =
this.CreateXmlBody("Quake3","infoRequest",this.RulesToXml(response));
//return the
XML
return returnValue;
}
As you can see there is almost no difference
between them.
Now they both run fine with the .NET runtime,
but with the mono runtime the .RequestStatus() fails.
When does it fail well when the QueryToString
function is called,
so if I run RequestInfo() the QueryToString
function is called and it all works fine,
if I run RequestStatus() the QueryToString
function is called and it goes wrong.
In my opinion the only difference so far is the
array of bytes to be sent.
Example:
Let's say I use the following code for an
application
using System;
using
TPSoftware.Q3PlugsNet;
using
TPSoftware.Q3PlugsNet.Exceptions;
class MainClass
{
public static
void Main(string[]
args)
{
//Create
a new Q3Query
// Q3Query quakeClient = new
Q3Query("195.130.132.153",27961);
Q3Query quakeClient = new
Q3Query("195.130.132.155",27961);
try
{
string
info =
quakeClient.RequestStatus();
Console.WriteLine(info);
}
catch
(Exception
e)
{
Console.WriteLine("ERROR:");
Console.WriteLine("\n"
+ e.ToString());
}
finally
{
Console.ReadLine();
}
}
}
Well then I get the following result with .NET
runtime

But I get the following with the mono
runtime:
Unhandled Exception:

However if I change the above code
to:
using System;
using
TPSoftware.Q3PlugsNet;
using
TPSoftware.Q3PlugsNet.Exceptions;
class MainClass
{
public static
void Main(string[]
args)
{
//Create

// Q3Query quakeClient = new
Q3Query("195.130.132.153",27961);
Q3Query quakeClient = new
Q3Query("195.130.132.155",27961);
try
{
string
info = quakeClient.RequestInfo(); // RequestInfo instead of RequestStatus
!!!!!!!!
Console.WriteLine(info);
}
catch
(Exception
e)
{
Console.WriteLine("ERROR:");
Console.WriteLine("\n"
+ e.ToString());
}
finally
{
Console.ReadLine();
}
}
}
I get the following output with
.NET
<?xml version="1.0" encoding="utf-7"

And the following output with mono (don't mind
the encoding, that's another bug)

So this works fine (more or less) and doesn't throw any errors.
So my question: Why does RequestStatus cause an error while RequestInfo
does not.
