Error with 'Equals' together with other parameters

[voliveriourmobo]

Hi,

I’m having a problem using your Dynamic LINQ lib regarding multiple where clauses.

When I try to filter a list using the query Manufacturer.Equals("samsung",StringComparison.OrdinalIgnoreCase) and BatteryLevel < 20, I get the following error:

“No property or field 'BatteryLevel' exists in type 'Char'”

But If I change the order of the sentence to ‘BatteryLevel < 20 and Manufacturer.Equals("samsung",StringComparison.OrdinalIgnoreCase)’ it works just fine, is this the expected behavior?

Stack Trace:

@voliveriourmobo I think this bug is introduced in the latest version 1.3.11

A fix in package 1.3.12 will be released soon.
