Hi

I am trying to create an instance of a nullable type using System.Activator
for example

t is passed in from the caller and is the Type info for a nullable type or
can be a standard type i.e string, int etc.

object value = Activator.CreateInstance(t);

value always returns null

>value always returns null

That makes sense since you haven't specified a value for the instance.

Hello DerekG,
object o = typeof(Nullable<>).MakeGenericType(new Type[] { typeof(int)
});
