How to get properties from parent class

Question

I want to use GetProperties to get the properties from the parent class via the child and, despite researching this, have been unsuccessful.

I tried the next without any result:

PropertyInfo[] fields = t.GetProperties();
PropertyInfo[] fields1 = t.GetProperties(BindingFlags.Public | BindingFlags.Instance | BindingFlags.FlattenHierarchy);
PropertyInfo[] propNames = t.BaseType.GetProperties( BindingFlags.Public | BindingFlags.Instance);

Just got it the properties from the child class, but dont get the properties from the parent.

Classes

public class A: B
{
    public string a1 { get; set; }

    public string a2 { get; set; }

    public string a3 { get; set; }

    public string a4 { get; set; }
}

public class B
{
    public string b1;
}

Using this code I am getting A's properties but not the property in B.

Does this code work? Do I need to configure something in some place?

Can you give us a sample of what your example classes look like, i.e. the `child` and its `parent` class? — Dandré, Feb 26 '19 at 19:19
This code works as expected for me, I got all base type properties. So what are you trying to achieve? — Alexander, Feb 26 '19 at 20:46
@Alexander. Just trying to get properties (in this case property) set on the parent class --> B. — Kenzo_Gilead, Feb 27 '19 at 08:14

In your declaration

public class B
{
    public string b1;
}

b1 is a field, not a property. You should either

Use GetFields():
```
FieldInfo[] fields = t.GetFields();
```
which will get the fields (as expected) - note that the documentation says that

Generally, you should use fields only for variables that have private or protected accessibility.
Make b1 a property, e.g. by adding { get; set; } accessors to it.
