Activator.CreateInstance(string) and Activator.CreateInstance<T>() difference
- by Juan Manuel Formoso
No, this is not a question about generics.
I have a Factory pattern with several classes with internal constructors (I don't want them being instantiated if not through the factory).
My problem is that CreateInstance fails with a "No parameterless constructor defined for this object" error unless I pass "true" on the non-public parameter.
Example
// Fails
Activator.CreateInstance(type);
// Works
Activator.CreateInstance(type, true);
I wanted to make the factory generic to make it a little simpler, like this:
public class GenericFactory<T> where T : MyAbstractType
{
public static T GetInstance()
{
return Activator.CreateInstance<T>();
}
}
However, I was unable to find how to pass that "true" parameter for it to accept non-public constructors (internal).
Did I miss something or it isn't possible?
