C#中读写INI配置文件
using System; using System.Collections.Generic; using System.Diagnostics; using System.IO; using System.Runtime.InteropServices; using System.Text; namespace ATESmartWheelBleTest { class Config { [DllImport("kernel32")]//返回0表示失败，非0为成功 private static extern long WritePrivateProfileString(string section, string key, string val, string filePath); [DllImport("kernel32")]//返回取得字符串缓冲区的长度 private static extern long GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath); static string iniPath = Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName) + "\\" + "ini.ini"; public static void InitIniFile() { if(!File.Exists(iniPath)) { //写初始值 WritePrivateProfileString("Wheel", "Circumference", "1", iniPath); } } public static void WriteWheelCircu(string data) { WritePrivateProfileString("Wheel", "Circumference", data, iniPath); } public static double GetWheelCircu() { try { StringBuilder retTemp = new StringBuilder(20); GetPrivateProfileString("Wheel", "Circumference", "", retTemp, 1024, iniPath); return double.Parse(retTemp.ToString()); } catch { return 0; } } } }

在作应用系统开发时，管理配置是必不可少的。例如数据库服务器的配置、安装和更新配置等等。由于Xml的兴起，现在的配置文件大都是以xml文档来存储。比如Visual Studio.Net自身的配置文件Mashine.config，Asp.Net的配置文件Web.Config，包括我在介绍Remoting中提到的配置文件，都是xml的格式。
传统的配置文件ini已有被xml文件逐步代替的趋势，但对于简单的配置，ini文件还是有用武之地的。ini文件其实就是一个文本文件，它有固定的格式，节Section的名字用[]括起来，然后换行说明key的值：
[section]
key=value
如数据库服务器配置文件：
DBServer.ini
[Server]
Name=localhost
[DB]
Name=NorthWind
[User]
Name=sa
在C#中，对配置文件的读写是通过API函数来完成的，代码很简单：
using System;using System.Text;using System.IO;using System.Runtime.InteropServices;namespace PubOp
{
public class OperateIniFile
{
API函数声明 读Ini文件 写Ini文件
}
}
简单说明以下方法WriteIniData()和ReadIniData()的参数。
Section参数、Key参数和IniFilePath不用再说，Value参数表明key的值，而这里的NoText对应API函数的def参数，它的值由用户指定，是当在配置文件中没有找到具体的Value时，就用NoText的值来代替。
