配置文件为fileName.ini 的文件

第一行必须为空，不然读不出值

[section1]


key=value
key2=value
.........

[section2]


key=value
key2=value
.........

代码如下:

using System;
using System.Runtime.InteropServices; 
using System.Text;

namespace Test
{
    /// <summary>
    /// INI文件的操作类
    /// </summary>
    public class IniFile
    {
        public string Path;

        public IniFile(string path)
        {
            this.Path = path;
        }
        
        #region 声明读写INI文件的API函数 
        [DllImport("kernel32")] 
        private static extern long WritePrivateProfileString(string section, string key, string val, string filePath); 

        [DllImport("kernel32")]
        private static extern int GetPrivateProfileString(string section, string key, string defVal, StringBuilder retVal, int size, string filePath); 

        [DllImport("kernel32")]
        private static extern int GetPrivateProfileString(string section, string key, string defVal, Byte[] retVal, int size, string filePath);
        #endregion

        /// <param name="iValue">值</param>
        public void IniWriteValue(string section, string key, string iValue) 
        {

        }

        {

            int i = GetPrivateProfileString(section, key, "", temp, 255, this.Path); 
            return temp.ToString();
        }

            return temp;
        }
    }
