c#操作ini文件的类

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();
}
}
}
操作ini文件
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
string Current;
Current = Directory.GetCurrentDirectory();//获取当前根目录
Ini ini = new Ini(Current + "/config.ini");
ini.Writue("Setting", "key1", "hello word!"); //写入ini文件
ini.Writue("Setting", "key2", "hello ini!");
ini.Writue("SettingImg", "Path", "IMG.Path");
string stemp = ini.ReadValue("Setting", "key2");//读取Setting章节的key2值
MessageBox.Show(stemp); //hello ini!
}
}
}
打开项目路径中的config.ini文件查看内容应该如下
[Setting]
key1=hello word!
key2=hello ini!
[SettingImg]
Path=IMG.Path
