|
Converting a type to another type without loosing data. Like taking an int to a long or a float to a double.
|
|

|
Why should you override the ToString method in a type?
|
To prevent boxing.
|
|
|
Why should you avoid boxing?
|
It adds overhead.
|
|
|
If a structure inherits ToString from System.Object, why would someone override that method within the structure?
|
To avoid boxing, since value type members are boxed when an abstract method inherited from System.Object is called. By default, the ToString method returns the type name, which typically is not useful.
|
|
|
