------------------------------------------------------------------
Is your code able to detect dynamic assemblies when running on Mono? There may
be dragons:
--- quote ---
if (assembly is System.Reflection.Emit.AssemblyBuilder)
{
return true;
}
try
{
if (assembly.GetType().FullName ==
"System.Reflection.Emit.InternalAssemblyBuilder")
{
return true;
}
}
catch (TargetInvocationException)
{
}
--- /quote ---
I'm inclined to keep the method as simple as:
--- quote ---
public static string AssemblyLocationInfo(Assembly myAssembly)
{
#if NETCF
return "Not supported on Microsoft .NET Compact
Framework";
#else
if (myAssembly.GlobalAssemblyCache)
{
return "Global Assembly Cache";
}
#if NET_4_0
else if (myAssembly.IsDynamic)
{
return "Dynamic Assembly";
}
#endif
else
{
try
{
// This call requires FileIOPermission
for access to the path
// if we don't have permission then we
just ignore it and
// carry on.
return myAssembly.Location;
}
catch (NotSupportedException)
{
// The location information may be
unavailable for dynamic assemblies and a NotSupportedException
// is thrown in those cases. See:
http://msdn.microsoft.com/de-de/library/system.reflection.assembly.location.aspx
return "Dynamic Assembly";
}
catch (ArgumentException ex)
{
return "Location Detect Failed (" +
ex.Message + ")";
}
catch (System.Security.SecurityException)
{
return "Location Permission Denied";
}
}
#endif
}

> Key: LOG4NET-388
> URL: https://issues.apache.org/jira/browse/LOG4NET-388
> Project: Log4net
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.2.11
> Reporter: Piotr Westfalewicz
> Priority: Minor
> Labels: easyfix, patch
> Attachments: NotSupportedExceptionInSystemInfo2.patch,
> NotSupportedExceptionInSystemInfo.patch
>
>
> For dynamic assemblies "Location" property shouldn't be used
> (http://msdn.microsoft.com/en-us/library/system.reflection.assembly.location.aspx).
> Therefore in log4net.Util.SystemInfo we can test if assembly is dynamic and
> in result avoid exception.
> Exception is very annoying and popular with NHibernate 3.3.3.4001.
> I have added both fix and test.
