Once again, in this series of posts I look at the parts of the. NET Framework, which may seem trivial, but can help improve Your code by making it easier to write and maintain.

Differences between the four cast operators of C ++Not my original ---------------------------------------------------------------------- Q: What is C style conversion? What are static_cast, dynamic_cast, and reinterpret_cast? What is the difference? Why? A: The meaning of conversion is to change the expression of a variable by changing its type to another type.
