Method overloading - good or bad design?

问题

I like to overload methods to support more and more default cases. What is the performance impact of method overloading? From your experience, is it advisable to overload methods? What is the limit? What are the workarounds?

回答1:

Overloading has no impact on performance; it's resolved by the compiler at compile-time.

As for design guidance, see the design guidelines:

If you're using C# 4.0 you can save your fingers some work and use optional parameters.

1. Performance impact, as far as I know, it's like defining a new method. The performance impact is space on your harddrive.
2. Advisable to overload methods, Definitely, it's provides convenience
3. What is the limit, As much Harddrive space as you have.
