  *

  A language is type-safe if the only operations that can be performed on data in the language are those sanctioned by the type of the data.

  *

  Explicit conversions (casts): Explicit conversions require a cast operator. Casting is required when information might be lost in the conversion, or when the conversion might not succeed for other reasons. Typical examples include numeric conversion to a type that has less precision or a smaller range, and conversion of a base-class instance to a derived class.

  Incorrect:

  Not (All data conversions are done implicitly/explicitly):

  In C#, you can perform the following kinds of conversions:

  / Implicit conversions: No special syntax is required because the conversion is type safe and no data will be lost. Examples include conversions from smaller to larger integral types, and conversions from derived classes to base classes.

  / Explicit conversions (casts): Explicit conversions require a cast operator.

  / User-defined conversions.

  / Conversions with helper classes

  D. Ability of the two languages to interoperate.
