由于在C#并没有提供专门读取INI文件的API,所以需要间接调用C++的API来进行读取。
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace 读写ini文件 { public class Ini { // 声明INI文件的写操作函数 WritePrivateProfileString() [System.Runtime.InteropServices.DllImport("kernel32")] private static extern long WritePrivateProfileString(string section, string key, string val, string filePath); // 声明INI文件的读操作函数 GetPrivateProfileString() [System.Runtime.InteropServices.DllImport("kernel32")] private static extern int GetPrivateProfileString(string section, string key, string def, System.Text.StringBuilder retVal, int size, string filePath); private string sPath = null; public Ini(string path) { this.sPath = path; } public void Writue(string section, string key, string value) { // section=配置节,key=键名,value=键值,path=路径 WritePrivateProfileString(section, key, value, sPath); } public string ReadValue(string section, string key) { // 每次从ini中读取多少字节 System.Text.StringBuilder temp = new System.Text.StringBuilder(255); // section=配置节,key=键名,temp=上面,path=路径 GetPrivateProfileString(section, key, "", temp, 255, sPath); return temp.ToString(); } } class Program { static void Main(string[] args) { string Current; Current = Directory.GetCurrentDirectory();//获取当前根目录 Console.WriteLine("Current directory {0}", Current); // 写入ini Ini ini=new Ini(Current+"/config.ini"); ini.Writue("Setting","key1","hello word!"); ini.Writue("Setting","key2","hello ini!"); ini.Writue("SettingImg", "Path", "IMG.Path"); // 读取ini string stemp = ini.ReadValue("Setting","key2"); Console.WriteLine(stemp); Console.ReadKey(); } } }
想要删除INI中的section的话,可以这样调用:
WritePrivateProfileString(section,null,null,sPath) 想要删除INI中的key的话,可以这样调用:
WritePrivateProfileString(section,key,null,sPath)
