A method call to a remote object that contains an enumeration field fails.
When I execute a method containing an enumeration, I receive the following
exception message:
"An unhandled exception of type 'System.IO.FileNotFoundException' occurred in
mscorlib.dll
Additional information: File or assembly name <metaData Assembly>, or one of
its dependencies, was not found."
where <metaData Assembly> is my metadata only assembly containing a stubbed-out
version of my remote object.
Here is the code for a simple remote object that illustrates the problem:
RemoteTest object (RemoteTest.cs)
----------------------------------------------
using System;
namespace Server
{
public enum DayOfWeek : int
{
Sunday = 0,
Monday = 1,
Tuesday = 2,
Wednesday = 3,
Thursday = 4,
Friday = 5,
Saturday = 6
}
public class RemoteTest : MarshalByRefObject
{
public RemoteTest()
{}
public string doSomething()
{
Console.WriteLine("doSomething() called");
return "someValue";
}
public string doSomething(DayOfWeek weekday)
{
Console.WriteLine("doSomething(DayOfWeek) called");
return Enum.GetName(typeof(DayOfWeek), weekday);
}
}
}
This class is hosted in a console application (RemoteServerConsole)
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
namespace Server
{
class RemoteServer
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
Console.WriteLine("Server.Main() started");
// Register Channel
TcpChannel chnl = new TcpChannel(1234);
ChannelServices.RegisterChannel(chnl);
// Register Remote object
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(RemoteTest),
"RemoteTest.rem",
WellKnownObjectMode.Singleton);
// the server will keep running until keypress
Console.ReadLine();
}
}
}
The stubbed out metadata-only assembly for the client:
using System;
namespace Server
{
public enum DayOfWeek : int
{
Sunday = 0,
Monday = 1,
Tuesday = 2,
Wednesday = 3,
Thursday = 4,
Friday = 5,
Saturday = 6
}
public class RemoteTest : MarshalByRefObject
{
private string message = "\nMethod can not be run locally.\nPlease check
your remoting configuration file.";
public RemoteTest()
{}
public string doSomething()
{ throw new NotSupportedException(message); }
public string doSomething(DayOfWeek weekday)
{ throw new NotSupportedException(message); }
}
}
Client Console application:
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using Server;
namespace Client
{
class ClientConsole
{
/// <summary>The main entry point for the application.</summary>
[STAThread]
static void Main(string[] args)
{
string filename = "ClientConsole.exe.config";
RemotingConfiguration.Configure(filename);
RemoteTest server = new RemoteTest();
// Execute a method with no enumeration parameters
Console.WriteLine("calling RemoteTest.doSomething()");
string result1 = server.doSomething();
Console.WriteLine("Result: " + result1);
// Execute method with enumeration parameter.
Console.WriteLine("calling RemoteTest.doSomething(DayOfWeek)");
string result2 = server.doSomething(Server.DayOfWeek.Monday);
Console.WriteLine("Result: " + result2);
}
}
}
Client Console configuration file (ClientConsole.exe.config)
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.runtime.remoting>
<application>
<client>
<wellknown type="Server.RemoteTest, RemoteTest_Meta"
url="tcp://localhost:1234/RemoteTest.rem" />
</client>
</application>
</system.runtime.remoting>
</configuration>
Does anyone know of a solution or workaround for this problem?
Sincerely,
Matthew Merrill
