Configuration file operations (INI, CFG, XML, config, etc.)

The format of the configuration file mainly includes INI, XML, config, etc., and now the operation of the configuration files in these formats (C #) is briefly explained.

INI configuration file operation

Call system Functions GetPrivateProfileString () and writeprivateprofilestring (), etc.

(1) Import library

[DllImport ("kernel32")]Private Static extern LongWritePrivateProfileString (stringSectionstringKeystringValstringFilePath); [DllImport ("kernel32")]Private Static extern intGetPrivateProfileString (stringSectionstringKeystringDef, StringBuilder RetVal,intSizestringFilePath);

(2) Calling function read/write INI configuration file

//ReadStringBuilder strcom =NewStringBuilder (255); GetPrivateProfileString ("Serial Port Parameters","Port","", Strcom,255,"Setting.ini");//WriteWritePrivateProfileString ("Serial Port Parameters","Port","COM3","Setting.ini");

CFG configuration file operation

configuration file Action component Sharpconfig is a. NET cfg/ini configuration file Action component.

Configuration file Example (SAMPLE.CFG):

[General]  == ten= 20.05= True

C # code example:

Configuration config = configuration.loadfromfile ("sample.cfg" ); Section Section= config[" General"];stringsomestring = section["somestring"]. Value;intSomeinteger = section["Someinteger"]. getvalue<int>();floatSomefloat = section["somefloat"]. getvalue<float> ();

The above Sharpconfig reference http://www.oschina.net/p/sharpconfig.

Config configuration file operation

The contents of the Appuser.config file are as follows:

<?XML version= "1.0" encoding= "Utf-8"?><Configuration>  <appSettings>    <AddKey= "Svrname"value= "127.0.0.1"></Add>    <AddKey= "DBName"value= "Warehousedb"></Add>    <AddKey= "Usrname"value= "sa"></Add>    <AddKey= "PassWord"value= "sa"></Add>  </appSettings>  <!--Connection Database String -  <connectionStrings>    <Addname= "Dbconnstring"connectionString= "server=gaohongchen\sqlexpress;database=egdb;uid=sa;pwd=123456"/>  </connectionStrings></Configuration>

The core code of the C # dbconnstring reading the Appuser.config file is as follows:

New== = cfgfile.connectionstrings.connectionstrings["dbconnstring "]. ConnectionString;
