C # how to read the INI File,

The INI file is used in the recent project to read the INI file. The method is as follows:

 

Using System; using System. collections. generic; using System. linq; using System. text; using System. collections. specialized; using System. IO; using System. runtime. interopServices; using System. windows. forms; namespace test {// <summary> // IniFiles class /// </summary> public class IniFiles {public string FileName; // INI file name // string path = System. IO. path. combine (Application. startupPath, "pos. ini "); // declare to read and write INI files API function of the component [DllImport ("kernel32")] private static extern bool WritePrivateProfileString (string section, string key, string val, string filePath); [DllImport ("kernel32")] private static extern int GetPrivateProfileString (string section, string key, string def, byte [] retVal, int size, string filePath); // class constructor, pass the INI file name public IniFiles (string AFileName) {// determine whether the file exists FileInfo fileInfo = new FileInfo (FileName); // Todo: Find out the usage of enumeration if ((! FileInfo. exists) {// | (FileAttributes. directory in fileInfo. attributes) // the file does not exist. Create the file System. IO. streamWriter sw = new System. IO. streamWriter (AFileName, false, System. text. encoding. default); try {sw. write ("# Table configuration file"); sw. close ();} catch {throw (new ApplicationException ("INI file does not exist");} // it must be a full path, not a relative path FileName = fileInfo. fullName;} // write the INI file public void WriteString (string Section, string Ide Nt, string Value) {if (! WritePrivateProfileString (Section, Ident, Value, FileName) {throw (new ApplicationException ("An error occurred while writing the INI file");} // read the INI file and specify public string ReadString (string Section, string Ident, string Default) {Byte [] Buffer = new Byte [65535]; int bufLen = GetPrivateProfileString (Section, Ident, Default, Buffer, Buffer. getUpperBound (0), FileName); // The Encoding method of 0 (the default code page of the system) must be set. Otherwise, the Chinese string s = Encoding cannot be supported. getEncoding (0 ). GetString (Buffer); s = s. substring (0, bufLen); return s. trim ();} // read integer public int ReadInteger (string Section, string Ident, int Default) {string intStr = ReadString (Section, Ident, Convert. toString (Default); try {return Convert. toInt32 (intStr);} catch (Exception ex) {Console. writeLine (ex. message); return Default ;}}// write the public void WriteInteger (string Section, string Ident, int Value ){ WriteString (Section, Ident, Value. toString ();} // read Boolean public bool ReadBool (string Section, string Ident, bool Default) {try {return Convert. toBoolean (ReadString (Section, Ident, Convert. toString (Default);} catch (Exception ex) {Console. writeLine (ex. message); return Default ;}}// write Bool public void WriteBool (string Section, string Ident, bool Value) {WriteString (Section, Ident, Convert. toSt Ring (Value);} // from the INI file, add all Ident in the specified Section name to the public void ReadSection (string Section, StringCollection Idents) in the list) {Byte [] Buffer = new Byte [16384]; // Idents. clear (); int bufLen = GetPrivateProfileString (Section, null, null, Buffer, Buffer. getUpperBound (0), FileName); // parse the Section GetStringsFromBuffer (Buffer, bufLen, Idents);} private void GetStringsFromBuffer (Byte [] Buffer, int bufLen, S TringCollection Strings) {Strings. Clear (); if (bufLen! = 0) {int start = 0; for (int I = 0; I <bufLen; I ++) {if (Buffer [I] = 0) & (I-start)> 0) {String s = Encoding. getEncoding (0 ). getString (Buffer, start, I-start); Strings. add (s); start = I + 1 ;}}}// read the names of all the functions from the INI file public void ReadSections (StringCollection SectionList) {// Note: it must be implemented using Bytes. StringBuilder can only obtain the first Section byte [] Buffer = new byte [65535]; int bufLen = 0; bufLen = GetPrivateProfileString (null, Buffer, Buffer. getUpperBound (0), FileName); GetStringsFromBuffer (Buffer, bufLen, SectionList);} // read all Values of a specified Section to public void ReadSectionValues (string Section, NameValueCollection Values) in the list) {StringCollection KeyList = new StringCollection (); ReadSection (Section, KeyList); Values. clear (); foreach (string key in KeyList) {Values. add (key, ReadStri Ng (Section, key, "") ;}}/** // read all values of the specified Section to the list, // public void ReadSectionValues (string Section, NameValueCollection Values, char splitString) // {string sealuvalue; // string [] sectionValueSplit; // StringCollection KeyList = new StringCollection (); // ReadSection (Section, KeyList); // Values. clear (); // foreach (string key in KeyList) // {// sectionValue = ReadString (Section, key ," "); // SectionValueSplit = sectionValue. split (splitString); // Values. add (key, sectionvaluesp.pdf [0]. toString (), sectionvaluesp.pdf [1]. toString (); //} // clear a Section public void EraseSection (string Section) {if (! WritePrivateProfileString (Section, null, null, FileName) {throw (new ApplicationException ("Section in ini file cannot be cleared "));}} // Delete the public void DeleteKey (string Section, string Ident) {WritePrivateProfileString (Section, Ident, null, FileName);} // Note: For Win9X, you need to implement the UpdateFile method to write the data in the buffer to the file // on Win NT, 2000, and XP, both are directly written to the file without buffering. Therefore, you do not need to implement UpdateFile // After modifying the INI file, you should call this method to update the buffer. Public void UpdateFile () {WritePrivateProfileString (null, FileName);} // check whether a key value in a Section has public bool ValueExists (string Section, string Ident) {StringCollection Idents = new StringCollection (); ReadSection (Section, Idents); return Idents. indexOf (Ident)>-1;} // ensure resource release ~ IniFiles () {UpdateFile ();}}}

Note: When using this class to read an INI file, the first line must be empty.
