C# Language Covarianza Array


Ejemplo

string[] strings = new[] {"foo", "bar"};
object[] objects = strings; // implicit conversion from string[] to object[]

Esta conversión no es de tipo seguro. El siguiente código generará una excepción de tiempo de ejecución:

string[] strings = new[] {"Foo"};
object[] objects = strings;

objects[0] = new object(); // runtime exception, object is not string
string str = strings[0];   // would have been bad if above assignment had succeeded
