Question

I’m trying to find a constructor with a specific signature. This constructor does not exist in current type, but it does in its parent. To illustrate:

public class Base
{
    public Base()
    {

    }

    public Base(string a1, string a2, string a3)
    {
        ...
    }
}

public class Child : Base
{

}

The problem is, that I can’t seem to find the .ctor with the string arguments with .GetConstructor, even trying such as:

typeof(Child).GetConstructor(BindingFlags.FlattenHierarchy | BindingFlags.Public | BindingFlags.Instance, null, new Type[] { typeof(string), typeof(string), typeof(string) }, null);

substituting typeof(Child) with typeof(Base), naturally, works.

Is there something I’m missing in respect to finding parent constructors?

Answer 1

Constructors are not inherited, so you can’t find them through children, even with FlattenHierarchy.

You’ll have to loop through children to find it.
