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 =3D 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 =3D new IPEndPoint(IPAddress.Any,0);
=20
//Receive the response
try
{
queryResponse =3D 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 =3D =
{0xFF,0xFF,0xFF,0xFF,0x67,0x65,0x74,0x73,0x74,0x61,0x74,0x75,0x73,0xA};
=20
//Create a new separator
char separator =3D Convert.ToChar(10);
//A statusRequest consists of both rules and players separated by =
char(10)
string[] response =3D this.QueryToString(query).Split(separator);
=20
//Get the rules and players
string rules =3D this.RulesToXml(response[0]);
string players =3D this.PlayersToXml(response);
=20
return =
this.CreateXmlBody("Quake3","statusRequest",string.Concat(rules,players))=
;
}
And
public string RequestInfo()
{
//Create the byte[] array to send
byte[] query =3D =
{0xFF,0xFF,0xFF,0xFF,0x67,0x65,0x74,0x69,0x6E,0x66,0x6F,0xA};
=20
//Query the server and get the response in a string
string response =3D this.QueryToString(query);
=20
//Create the default xml body and put the rules in it
string returnValue =3D =
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)
{
=20
//Create a new Q3Query
=20
// Q3Query quakeClient =3D new Q3Query("195.130.132.153",27961);
Q3Query quakeClient =3D new Q3Query("195.130.132.155",27961);
=20
try
{
string info =3D quakeClient.RequestStatus();
Console.WriteLine(info);
}
catch (Exception e)
{
Console.WriteLine("ERROR:");
Console.WriteLine("\n" + e.ToString()); =20
=20
}
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)
{
=20
//Create a new Q3Query
=20
// Q3Query quakeClient =3D new Q3Query("195.130.132.153",27961);
Q3Query quakeClient =3D new Q3Query("195.130.132.155",27961);
=20
try
{
string info =3D quakeClient.RequestInfo(); // RequestInfo instead of =
RequestStatus !!!!!!!!
Console.WriteLine(info);
}
catch (Exception e)
{
Console.WriteLine("ERROR:");
Console.WriteLine("\n" + e.ToString()); =20
=20
}
finally
{
Console.ReadLine();
}
}
}
I get the following output with .NET
<?xml version=3D"1.0" encoding=3D"utf-7" =
standalone=3D"yes"?><Q3Plugs.NET><Query type=3D
"infoRequest" protocol=3D"Quake3"><Server ipadress=3D"195.130.132.155" =

And the following output with mono (don't mind the encoding, that's =
another bug)
???xml version???1.0?? encoding???utf-7?? standalone???yes???? =
??Q3Plugs.NET? ??
Query type???infoRequest?? protocol???Quake3??? ??Server =

???+-???/rule???+QAA-/Rules?????/Query? ??/Q3Plugs.NET?
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.
