C#操作ini文件的帮助类

.ini 文件是Initialization File的缩写，即初始化文件，是windows的系统配置文件所采用的存储格式，统管windows的各项配置，一般用户就用windows提供的各项图形化管理界面就可实现相同的配置了。但在某些情况，还是要直接编辑ini才方便，一般只有很熟悉windows才能去直接编辑。

一、定义Class

using System;
using System.Runtime.InteropServices;
using System.Text;

namespace IniDemo
{
public class IniFile
{
private string m_FileName;

public string FileName
{
get
{
return this.m_FileName;
}
set
{
this.m_FileName = value;
}
}

[DllImport("kernel32.dll")]
private static extern int GetPrivateProfileInt(string lpAppName, string lpKeyName, int nDefault, string lpFileName);

[DllImport("kernel32.dll")]
private static extern int GetPrivateProfileString(string lpAppName, string lpKeyName, string lpDefault, StringBuilder lpReturnedString, int nSize, string lpFileName);

[DllImport("kernel32.dll")]
private static extern int WritePrivateProfileString(string lpAppName, string lpKeyName, string lpString, string lpFileName);

public IniFile(string aFileName)
{
this.m_FileName = aFileName;
}

public IniFile()
{
}

public int ReadInt(string section, string name, int def)
{
return IniFile.GetPrivateProfileInt(section, name, def, this.m_FileName);
}

public string ReadString(string section, string name, string def)
{
StringBuilder stringBuilder = new StringBuilder(2048);
IniFile.GetPrivateProfileString(section, name, def, stringBuilder, 2048, this.m_FileName);
return stringBuilder.ToString();
}

public void WriteInt(string section, string name, int Ival)
{
IniFile.WritePrivateProfileString(section, name, Ival.ToString(), this.m_FileName);
}

public void WriteString(string section, string name, string strVal)
{
IniFile.WritePrivateProfileString(section, name, strVal, this.m_FileName);
}

public void DeleteSection(string section)
{
IniFile.WritePrivateProfileString(section, null, null, this.m_FileName);
}

public void DeleteAllSection()
{
IniFile.WritePrivateProfileString(null, null, null, this.m_FileName);
}

public string IniReadValue(string section, string name)
{
StringBuilder stringBuilder = new StringBuilder(256);
IniFile.GetPrivateProfileString(section, name, "", stringBuilder, 256, this.m_FileName);
return stringBuilder.ToString();
}

public void IniWriteValue(string section, string name, string value)
{
IniFile.WritePrivateProfileString(section, name, value, this.m_FileName);
}
}
}

二、调用方法

IniFile iniFile = new IniFile(Environment.CurrentDirectory + "\\LocalInf.ini");
//读取Local节点下M的值，默认为空值
string m  = iniFile.ReadString("Local", "M", "");
//Local节点下写F=f
iniFile.WriteString("Local", "F", "f");
//读取Local节点下IsSleep的字符串值，并转为bool类型值,给出默认值为False
bool f = bool.Parse(iniFile.ReadString("Local", "IsSleep", "False"));
//读取Local节点下的C的字符串值，并转为double类型值，给出默认值0
bool f = double.Parse(iniFile.ReadString("Local", "C", "0"));
