Create empty array using reflection [duplicate]

Question

How do I create empty array of a type given by reflection? I have tried using the Activator.CreateInstance(Type) method:

Type arrayType = typeof(string[]);
Activator.CreateInstance(arrayType);

but I get a MissingMethodException exception:

System.MissingMethodException: No parameterless constructor defined for this object.

What am I doing wrong?

Some types you have to trap and handle special, for your case you'd use:

if ( type.IsArray){
  var o = Array.CreateInstance(type, size);
}
