Extracting attribute data from decorated properties

Is there any method to select only the properties that are decorated with a specified Attribute and extract the Attribute data ...all in one pass?

Currently i am first doing a PropertyInfo filtering and then i am getting the Attribute data:

Attribute data

 public class Weight {
        public string Name { get; set; }
        public double Value { get; set; }
        public Weight(string Name,double Value) {
            this.Name = Name;
            this.Value = Value;
        }
    }

Attribute

[AttributeUsage(AttributeTargets.Property)]
    public class WeightAttribute : Attribute {
        public WeightAttribute(double val,[CallerMemberName]string Name=null) {
            this.Weight = new Weight(Name, val);
        }
        public Weight Weight { get; set; }
    }

Extractor

private static IReadOnlyList<Weight> ExtractWeights(Type type) {
   var properties = type.GetProperties(BindingFlags.Instance | BindingFlags.Public | BindingFlags.DeclaredOnly)
                                  .Where(x => x.GetCustomAttribute<WeightAttribute>() != null) ;
   var weights = properties.Select(x => x.GetCustomAttribute<WeightAttribute>().Weight).ToArray();
                        return weights;
                    }

As you can see in my Extractor method i am first filtering the PropertyInfo[] and then getting the data's.Is there any other more efficient way?
