How to exclude properties of father class

Question

Suppose I have the following two classes.

  public class Father
    {
        public int Id { get; set; }
        public int Price { get; set; } 
    }
    public class Child: Father
    {
        public string Name { get; set; }
    }

How can I know if a specific property is a Father property (Inherited) or a Child property?

I tried

var childProperties = typeof(Child).GetProperties().Except(typeof(Father).GetProperties());

but seems like Except is not detecting the equality of Father properties and Child inherited properties.

Answer 1

Use the overload on GetProperties that accepts BindingFlags. Include the DeclaredOnly flag next to the Public and Instance flags and you're all set:

var childProperties = typeof(Child)
            .GetProperties(
                BindingFlags.Public | 
                BindingFlags.Instance | 
                BindingFlags.DeclaredOnly  // to search only the properties declared on 
                                           // the Type, not properties that 
                                           // were simply inherited.
            );

This will return one property, the Name.

Notice that with this solution you don't need to inspect the DeclaringType.

Answer 2

Just try like this;

var childPropertiesOnly = typeof(Child)
         .GetProperties()
         .Where(x => x.DeclaringType != typeof(Father))
         .ToList();
