C# 读取ini文件,以及读不出来原因

    public class IniFiles
    {
        public string inipath;

        //声明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 def, StringBuilder retVal, int size, string filePath);
        /// <summary> 
        /// 构造方法 
        /// </summary> 
        /// <param name="INIPath">文件路径</param> 
        public IniFiles(string INIPath)
        {
            inipath = INIPath;
        }

        public IniFiles() { }

        /// <summary> 
        /// 写入INI文件 
        /// </summary> 
        /// <param name="Section">项目名称(如 [TypeName] )</param> 
        /// <param name="Key">键</param> 
        /// <param name="Value">值</param> 
        public void IniWriteValue(string Section, string Key, string Value)
        {
            WritePrivateProfileString(Section, Key, Value, this.inipath);
        }
        /// <summary> 
        /// 读出INI文件 
        /// </summary> 
        /// <param name="Section">项目名称(如 [TypeName] )</param> 
        /// <param name="Key">键</param> 
        public string IniReadValue(string Section, string Key)
        {
            StringBuilder temp = new StringBuilder(500);
            int i = GetPrivateProfileString(Section, Key, "", temp, 500, this.inipath);
            if (i < 0)
            {
                return "";
            }
            return temp.ToString();
        }
        /// <summary> 
        /// 验证文件是否存在 
        /// </summary> 
        /// <returns>布尔值</returns> 
        public bool ExistINIFile()
        {
            return File.Exists(inipath);
        }
    }

通过api函数GetPrivateProfileString读取ini文件,取不到值。

方法:

1)将ini文件的编码格式,由utf8,改为unicode;

2)ini文件的第一行不能是有效内容(不能为section)。【空一行出来】
