Type doesn't contain property with name 'System.Object'

[tankbob]

if the property name passed to property is not a straight string then the detection engine doesn't seem to correctly identify and shows an error as doesn't contain a property with name 'System.Object'.

For example the following line:

typeof(Payment).GetProperty(paymentType + (isRefund) ? "Refund" : String.Empty));

As it may not be possible to correctly decode the variable it is possibly worth creating a different inspection type of "Dynamic Property Name invocation" that can be set to warning rather than error.

I don't know if it's the same exact problem, but I'm also getting this on this following code:

public class Helper
{
    protected static IEnumerable<string> GetMethodParameterNames<T>(Expression<Func<T, object>> methodInvocation)
    {
        var method = typeof(T).GetMethod(For<T>.GetName(methodInvocation));  // <---- error here (see image)

        var parameterNames = method.GetParameters().Select(p => p.Name);

        return parameterNames;
    }

    private class For<T>
    {
        public static string GetName<T>(Expression<Func<T, object>> methodInvocation)
        {
            // omitted, get the name of the calling method

            return null;
        }
    }
}

Yes, the reason is the same - incorrect logic in ResolveMember with non-constant name arguments. Validations shouldn't be executed at all in such case. Will be fixed in next release.
