c# 解决ini中文乱码_ini配置文件保存的是乱码

乱码仅仅是因为编码规则导致

解码时对应文件的码制即可  ,

方法一 : 有可能出问题

    public class IniConfig
    {
        private string inipath = AppDomain.CurrentDomain.BaseDirectory + "Config1.ini";
        public bool CanRead()
        {
            if (File.Exists(inipath))
            {
                return true;
            }
            return false;
        }
        //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 long WritePrivateProfileString(string section, string key, byte[] retVal, string filePath);
 
        [DllImport("kernel32")]
        private static extern int GetPrivateProfileString(string section, string key, string def, byte[] retVal, int size, string filePath);
        [DllImport("kernel32")]
        private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
        /// <summary> 
        /// 写入INI文件 
        /// </summary> 
        public void IniWriteValue(string Section, string Key, string Value)
        {
            WritePrivateProfileString(Section, Key, Value, inipath);
        }
        public void IniWriteValue(string Section, string Key, string Value, Encoding encoding)
        {
            byte[] retVal = encoding.GetBytes(Value);
            WritePrivateProfileString(Section, Key, retVal, inipath);
        }
        /// <summary> 
        ///读INI文件: 含有中文时,请使用此方法  Encoding.Default 
        /// </summary> 
        public string IniReadValue(string Section, string Key, Encoding encoding)
        {
            try
            {
                byte[] Buffer = new byte[200];
                int bufLen = GetPrivateProfileString(Section, Key, "", Buffer, Buffer.GetUpperBound(0), inipath);
                string s = encoding.GetString(Buffer);
                s = s.Substring(0, bufLen);
                return s.Trim();
            }
            catch (Exception)
            {
                return "";
            }
        }
        public string IniReadValue(string Section, string Key)
        {
            try
            {
                StringBuilder temp = new StringBuilder(500);
                int i = GetPrivateProfileString(Section, Key, "", temp, 500, inipath);
                return temp.ToString();
            }
            catch (Exception)
            {
                return "";
            }
        }
    }

调用:

 IniConfig ic = new IniConfig();

 if (!ic.CanRead())
 {ic.IniWriteValue("DataBase", "Connect", "你好啊",Encoding.UTF8);}

//有中文时指定编码格式

ic.IniReadValue("DataBase", "Connect", Encoding.UTF8);

//没有中文直接调用

ic.IniReadValue("DataBase", "Connect");

备注:  有可能出现  本机调试好用,目标机修改ini后就不正常了

原因:依旧是ini默认编码不一样,大概就是uft-8  与utf-8 bom的事情了 

**************尚不知道怎么蹦出来的bom*******************

解决办法:在新电脑上重新生成ini文件,指定Encoding.UTF8就可以了

一劳永逸的办法就是采用下面的类库

直接指定编码格式

方法二:

    public class IniFile
    {
        private string filePath = AppDomain.CurrentDomain.BaseDirectory + "Config.ini";
        private Dictionary<string, Dictionary<string, string>> sections = new Dictionary<string, Dictionary<string, string>>();
 
        public IniFile()
        {
            Load();
        }
 
        private void Load()
        {
            sections.Clear();
 
            if (!File.Exists(filePath))
            {
                return;
            }
            //使用 utf-8 格式读取
            using (StreamReader reader = new StreamReader(filePath, Encoding.UTF8))
            {
                string line;
                string sectionName = null;
                while ((line = reader.ReadLine()) != null)
                {
                    line = line.Trim();
                    if (line.StartsWith(";") || line.Length == 0)
                    {
                        // 注释或空行，忽略
                        continue;
                    }
 
                    if (line.StartsWith("[") && line.EndsWith("]"))
                    {
                        // 新节开始
                        sectionName = line.Substring(1, line.Length - 2).Trim();
                        sections[sectionName] = new Dictionary<string, string>();
                    }
                    else
                    {
                        // 键值对
                        int index = line.IndexOf('=');
                        if (index > 0)
                        {
                            string key = line.Substring(0, index).Trim();
                            string value = line.Substring(index + 1).Trim();
                            if (!string.IsNullOrEmpty(sectionName))
                            {
                                sections[sectionName][key] = value;
                            }
                        }
                    }
                }
            }
        }
 
        private void Save()
        {
            //默认 utf-8 格式
            using (StreamWriter writer = new StreamWriter(filePath, false))
            {
                foreach (var section in sections)
                {
                    writer.WriteLine($"[{section.Key}]");
                    foreach (var setting in section.Value)
                    {
                        writer.WriteLine($"{setting.Key}={setting.Value}");
                    }
                    writer.WriteLine(); // 空行分隔不同的节
                }
            }
        }
 
        public string Get(string section, string key)
        {
            if (sections.ContainsKey(section) && sections[section].ContainsKey(key))
            {
                return sections[section][key];
            }
            return null;
        }
 
        public void Set(string section, string key, string value)
        {
            if (!sections.ContainsKey(section))
            {
                sections[section] = new Dictionary<string, string>();
            }
            sections[section][key] = value;
            Save();
        }
    }

调用: 

IniFile iniFile = new IniFile();

//写入

iniFile.Set("fan", "aaaa", "你好啊1");

//读取

iniFile.Get("fan", "aaaa")
