Array covariance C# with Example
string[] strings = new[] {"foo", "bar"}; object[] objects = strings; // implicit conversion from string[] to object[] This conversion is not type-safe. The following code will raise a runtime exception: 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
