这篇文章主要介绍了C#实现利用Windows API读写INI文件的方法,涉及C#针对ini文件的创建、读取及写入等操作技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了C#实现利用Windows API读写INI文件的方法。分享给大家供大家参考。具体如下:
写入时,如果没有INI文件,自动创建INI
如果在创建时,GetLastError:5 检查IniPath是否添加了文件名称.ini
- using System;
- using System.Collections.Generic;
- using System.Text;
- using System.IO;
- using System.Runtime.InteropServices;
- namespace NameSpace
- {
