How to I determine LookupError.NotFound from AggregateException

Here is code:

try{

pFilesRoutes.GetMetadataAsync("/shesnotthere", false)

}catch(AggregateException e)

{

foreach (var err in e.InnerExceptions)

{

if (err is LookupError.NotFound)

do something

}}}

How do I "dig out" the correct error and check its type ?

Here's a small sample of how you can explicitly check for an error like NotFound:

 try {
    var metadata = await this.client.Files.GetMetadataAsync("/non-existant path");
    Console.WriteLine(metadata.Name);
} catch (Dropbox.Api.ApiException<Dropbox.Api.Files.GetMetadataError> e) {

    if (e.ErrorResponse.IsPath) {
        var pathError = e.ErrorResponse.AsPath.Value;
        if (pathError.IsNotFound) {
            Console.WriteLine ("File or folder not found.");
        } else {
            Console.WriteLine (pathError);
        }
    } else {
        Console.WriteLine (e.ErrorResponse);
    }
}

Hope this helps!
