Preface
- In fact, we have mastered the configuration file , Reading and writing functions and methods of text files , If one INI The file has only a few key value pairs , So it's OK to use built-in functions , But when
INIThere are many key value pairs in the file , The way of reading and writing built-in functions one by one is very cumbersome , This section aims at this situationINIUpgrade the file by reading and writing , In order to read and write multi key value pairs quickly and conveniently- Demonstrate hardware and software environment Win10 x64 ; CANoe 11 SP2 x64

Explanation of batch reading code
- 1️⃣ This demonstration is still based on
bmw2.cfg, Add a new oneNework Node, Used for key trigger test
- 2️⃣ Below
test.iniThe file is our test file , There are many key value pairs
- 3️⃣ We follow our programming habits , The control statement is placed in IniAuto.can In file , Functions and global variables are placed in
IniAuto.cinIn file IniAuto.canIn the code ：
/*@!Encoding:936*/

- 5️⃣ The header file
IniAuto.cinThe definition of "bad" in
explain ： Because it involves batch operation , Everything is broken up , Allkey/valueAll data types of are treated as string operations , In the actual code , If there is an integer floating point , Please perform format conversion again
- 6️⃣ The header file
IniAuto.ciningetKeyValueFromINIComments on functions
7️⃣ Key
’u‘, Look at the test results ：We have ini Key value pairs of are converted to CAPl Array type of , In this way, no matter how we read in batches in the next step , rewrite , Delete
Explanation of batch writing code
1️⃣ After we read it , The possible operation is rewriting , Delete , add to , Even new operations , After this series of operations , We have to save it to the original INI Of documents .
2️⃣ We follow our programming habits , The control statement is placed in IniAuto.can In file , Functions and global variables are placed in
