How to create an object instance of class with internal constructor via reflection?

Question

Example:

class Program
{
    static void Main(string[] args)
    {
        var myClass = Activator.CreateInstance(typeof(MyClass));
    }
}

public class MyClass
{
    internal MyClass()
    {
    }
}

Exception:

System.MissingMethodException

No parameterless constructor defined for this object.

Solution:

var myClass = Activator.CreateInstance(typeof(MyClass), nonPublic:true);

I cannot understand, why I cannot create an instance inside the assembly with internal constructor. This constructor should be available inside the execution assembly. It should work like public for this assembly.

Answer 1

It is not that impossible. you've to tell it is not a public.

var myClass = Activator.CreateInstance(typeof(MyClass), true);//say nonpublic

Answer 2

The constructor inside your MyClass is Internal try to change to public

public class MyClass
{
    public MyClass()
    {
    }
}

or

Pass true to CreateInstance

var myClass = Activator.CreateInstance(typeof(MyClass),true );
