DynamicExpressionParser.ParseLambda() Not working on Android

[ErickMVI]

Hello! I had a quick question of the System.Linq.Dynamic.Core.DynamicExpressionParser Class specifically for Android platforms. When calling the
DynamicExpressionParser.ParseLambda() function it throws a System.IOException on Android devices. I skimmed through the source code and found out that it calls DefaultAssemblyHelper.GetAssemblies() which uses Directory.GetFiles(AppDomain.CurrentDomain.BaseDirectory, "*.dll")

However, AppDomain.CurrentDomain.BaseDirectory is just a "/" on Android devices which causes the exception.

Is there any workaround for this? Thank you for your time!

Thanks for bringing this up. I would not know of a work-around, probably a fix needs to be made.

@StefH Thanks for looking into it.

I'm not 100% sure that this is the error, because there is a try-catch in that code:

string[] referencedPaths;
try
{
    referencedPaths = Directory.GetFiles(AppDomain.CurrentDomain.BaseDirectory, "*.dll");
}
catch
{
    referencedPaths = [];
}

So in case the AppDomain.CurrentDomain.BaseDirectory is a "/" , this will throw, but the ctahc will make sure that referencedPaths is just empty array.

Are you sure this is the location for your error?

• Can you provide a example project ?
• Or provide some more exception stack tracing?
