C# 读取ini文件 | 易学教程

ini文件介绍

ini文件是微软操作系统上的配置文件，格式如下

;此处是注释

key2=value2

[section2]

注意：注释符号为分号

c#操作ini文件的类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace WindowsFormsApplication1
{
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.IO;

        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();

}

}
}

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
