筛选器Type.GetProperties（），其中PropertyType.Name在列表中

Question

I need to show only the properties that have names that are in the requiredfield list.

I'm trying to do something like this but p.PropertyType.Name == x is not correct:

Pricing pricing = new Pricing();
Type type = typeof(Pricing);
PropertyInfo[] PricingProperties = type.GetProperties();

PricingRequiredFieldDAL requiredField = new PricingRequiredFieldDAL();

var x = requiredField.GetRequiredFields();

var list = PricingProperties.Where(p => p.PropertyType.Name == x);

public class PricingRequiredFieldDAL
{
    PricingContext db = new PricingContext();

    public List<PricingRequiredField> GetRequiredFields()
    {
        return db.PricingRequiredFields.Where(p => p.Required == true).ToList();
    }
}

How would I go about getting the information I want using reflection in the above fashion?

Answer 1

Just something like:

var fieldNames = new HashSet<string>(x.Select(p => p.Name));
var properties = PricingProperties.Where(p => fieldNames.Contains(p.Name));

That's assuming that PricingRequiredField has a property called Name . You haven't actually told us that.

Answer 2

Try this:

var list = PricingProperties.Where(p => x.Contains(p.PropertyType.Name));

I supposed x is a list.
