我会尝试尽可能多地提出一个问题的答案，尽可能多的技术问题...... />

结构是一个旧学校。将数据元素组合成一个单元格的方法。


之后出现了类，它们是一个允许

的结构继承和其他OO之类的东西。


结构稍微简单的生物是精益和平均，即

它们工作速度快但缺乏功能。


示例.NET stucts Point，Rectangle DateTime。注意这些是如何简单的操作通常是性能关键的。


当事情变得更复杂时，类很有用。即你需要

继承或其他东西。


结构和类有不同的pitfals可能会让新的
程序员感到惊讶。 />
即


a struct不能为nul但是一个类可以..

struct a = stuct b copyies bto a

a类= b类意味着a也称为b。


希望这个基本概述有帮助。

I will try to give a simle answer gloassing over as many technical
issues as I can...

Structs are an "old school" method of combineing data elements into one
unit.

Class came along afterwards, they are esentuly a struct which allows
for things like inheritance and other OO stuff.

Structs being somewhat simpler creatures are "lean and mean", that is
they work fast but lack features.

Example .NET stucts Point, Rectangle DateTime. Note how these are
simple operations which are often performance critical.

Classes are usefull when things get more complicated. Ie you need
inheritance or something.

Struct and Classes have different pitfals that may suprise the new
programmer.
ie

a struct can not be nul but a class can..
struct a = stuct b copyies bto a
class a = class b means a is also called b.

hope this "basic" overview helps.
