All variables that you base on these types are reference variables.
// new operator makes the variable non-null
myDictionary Dictionary = new Dictionary;
// so does an empty set-values block
myDictionary Dictionary{};
Array variables are also initially null, but you can initialize them by specifying a size. For more information, see Arrays.
Assignments and comparisons for reference variables follow different rules than those for value-based variables. For more information, see Reference compatibility in EGL.
