ini文件介绍：

; bashful [bashful] weight = 45.7 height = 98.8 age = 67 homePage = http://snowwhite.tale/~bashful homeDir = /home/bashful ; doc [doc] weight = 49.5 height = 87.7 age = 63 homePage = http://doc.dwarfs homeDir = c:\Documents and Settings\doc

在该文件中有三种数据：

1. ; bashful 像这种  ;  表示该行是注释，符号后面表示注释的内容

2. [bashful] 像这种 [ ]里面的就是session

3. 后面=两边表示的是键值对存储的数据，左边的是key，右边的是value

不带session和注释的ini文件：

文件保存的数据只有键值对形式

weight = 45.7

height = 98.8 age = 67

homePage = http://snowwhite.tale/~bashful

homeDir = /home/bashful
