C# reads the ini file

Without further ado, let’s get right to the code

1: introduces the namespace

System.Runtime.InteropServices
System.IO
Copy the code

2: Write an iniHelper class

 public class IniHelper{[DllImport("kernel32")]// Return 0 for failure, non - 0 for success
        private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
        [DllImport("kernel32")]// Returns the length of the string buffer
        private static extern long GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);

        /// <summary>
        ///Reading an INI File
        /// </summary>
        /// <param name="Section">The name of the</param>
        /// <param name="Key">The keyword</param>
        /// <param name="defaultText">The default value</param>
        /// <param name="iniFilePath">Ini File address</param>
        /// <returns></returns>
        public static string GetValue(string Section, string Key, string defaultText, string iniFilePath)
        {
            if (File.Exists(iniFilePath))
            {
                StringBuilder temp = new StringBuilder(1024);
                GetPrivateProfileString(Section, Key, defaultText, temp, 1024, iniFilePath);
                return temp.ToString();
            }
            else
            {
                returndefaultText; }}/// <summary>
        ///Write an INI file

        /// <param name="defaultText">The default value</param>
        /// <param name="iniFilePath">Ini File address</param>
        /// <returns></returns>
        public static bool SetValue(string Section, string Key, string Value, string iniFilePath)
        {
            var pat = Path.GetDirectoryName(iniFilePath);
            if (Directory.Exists(pat) == false)
            {
                Directory.CreateDirectory(pat);
            }
            if (File.Exists(iniFilePath) == false)
            {
                File.Create(iniFilePath).Close();
            }
            long OpStation = WritePrivateProfileString(Section, Key, Value, iniFilePath);
            if (OpStation == 0)
            {
                return false;
            }
            else
            {
                return true; }}}Copy the code

5: You can either manually create an INI file or automatically create an INI file

My INI file is configured like this: [my data] MyID=9527Copy the code

4: Direct call

 string MyID = Console.ReadLine();
           // Write to the file
            string file = System.Environment.CurrentDirectory + @"\config.ini";
            if(file! =null)
            {
                IniHelper.SetValue("My data"."MyID", MyID, file);
            }
            Console.WriteLine("The ID I entered was {0}",MyID);
            // Read the file
            if(file ! =null)
            {
                MyID = IniHelper.GetValue("My data"."MyID"."", file);
                Console.WriteLine("The ID I read is {0}"+MyID);
                Console.ReadLine();
            }
