C# 读取ini文件，读不出来原因

先赋上相关读取ini文件代码

public class INIHelper
    {
        public string inipath;
        [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);

        public INIHelper(string INIPath)
        {
            inipath = INIPath;
        }

        public void set(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 ReadInivalue(string Section, string Key)
        {
            StringBuilder temp = new StringBuilder(500);
            int i = GetPrivateProfileString(Section, Key, "", temp, 500, this.inipath);
            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);
        }

    }

　　调用以上方法的代码

INIHelper iniHelper = new INIHelper(Application.StartupPath + "\\Level.ini");
private void ConfigureShowHighFrm_Load(object sender, EventArgs e)
        {
            if (iniHelper.ReadInivalue("config", "high") == "1")
                checkBox1.Checked = true;
            else
                checkBox1.Checked = false;

            if (iniHelper.ReadInivalue("config", "hit") == "1")
                checkBox2.Checked = true;
            else
                checkBox2.Checked = false;

            if (iniHelper.ReadInivalue("config", "low") == "1")
                checkBox3.Checked = true;
            else
                checkBox3.Checked = false;
        }

　　然后再看ini文件截图

不知道看到没有这个图片，这个就是ini文件第一行必须是空格，否则读不出来哦！！！
