c#读取ini配置文件实例

配置文件

配置文件放在应用目录下，配置文件config.ini示例如下：

[Setting]
ip=192.168.1.1
port=8080

代码示例：

using System;
using System.IO;
using read_write_ini;

namespace read_write_ini
{
    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，读取该键名的值最大长度，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", "key1 value");
        //ini.Writue("Setting", "key2", "key2 value");
        //ini.Writue("SettingImg", "Path", "IMG.Path");
        // 读取ini  
        string stemp = ini.ReadValue("Setting", "ip");
        Console.WriteLine(stemp);
        Console.ReadKey();
    }
}

运行结果
