C#读写INI文件的方法

类文件内容如下，读者如果要使用这个类需要引用命名空间：using System.Runtime.InteropServices;    

实例化此类时需要将要操作的INI文件的路径作为构造函数的参数。

    /// <summary>

    /// INI文件的操作类

    /// </summary>

    public class IniFile

    {

        public string Path;

        public IniFile(string path)

        {

            this.Path = path;

        }

        //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);
