最近项目用到ini文件,读取ini文件,方法如下:
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的类
/// </summary>
public class IniFiles
{
public string FileName; //INI文件名
//string path = System.IO.Path.Combine(Application.StartupPath,"pos.ini"); //声明读写INI文件的API函数
[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); //类的构造函数,传递INI文件名
public IniFiles(string AFileName)
{
// 判断文件是否存在
FileInfo fileInfo = new FileInfo(AFileName);
//Todo:搞清枚举的用法
if ((!fileInfo.Exists))
{ //|| (FileAttributes.Directory in fileInfo.Attributes))
//文件不存在,建立文件
System.IO.StreamWriter sw = new System.IO.StreamWriter(AFileName, false, System.Text.Encoding.Default);
try
{
sw.Write("#表格配置档案");
sw.Close();
}
catch
{
throw (new ApplicationException("Ini文件不存在"));
}
}
//必须是完全路径,不能是相对路径
FileName = fileInfo.FullName;
} //写INI文件
public void WriteString(string Section, string Ident, string Value)
{
if (!WritePrivateProfileString(Section, Ident, Value, FileName))
{ throw (new ApplicationException("写Ini文件出错"));
}
} //读取INI文件指定
public string ReadString(string Section, string Ident, string Default)
{
Byte[] Buffer = new Byte[];
int bufLen = GetPrivateProfileString(Section, Ident, Default, Buffer, Buffer.GetUpperBound(), FileName);
//必须设定0(系统默认的代码页)的编码方式,否则无法支持中文
string s = Encoding.GetEncoding().GetString(Buffer);
s = s.Substring(, bufLen);
return s.Trim();
} //读整数
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;
}
} //写整数
public void WriteInteger(string Section, string Ident, int Value)
{
WriteString(Section, Ident, Value.ToString());
} //读布尔
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;
}
} //写Bool
public void WriteBool(string Section, string Ident, bool Value)
{
WriteString(Section, Ident, Convert.ToString(Value));
} //从Ini文件中,将指定的Section名称中的所有Ident添加到列表中
public void ReadSection(string Section, StringCollection Idents)
{
Byte[] Buffer = new Byte[];
//Idents.Clear(); int bufLen = GetPrivateProfileString(Section, null, null, Buffer, Buffer.GetUpperBound(), FileName);
//对Section进行解析
GetStringsFromBuffer(Buffer, bufLen, Idents);
} private void GetStringsFromBuffer(Byte[] Buffer, int bufLen, StringCollection Strings)
{
Strings.Clear();
if (bufLen != )
{
int start = ;
for (int i = ; i < bufLen; i++)
{
if ((Buffer[i] == ) && ((i - start) > ))
{
String s = Encoding.GetEncoding().GetString(Buffer, start, i - start);
Strings.Add(s);
start = i + ;
}
}
}
} //从Ini文件中,读取所有的Sections的名称
public void ReadSections(StringCollection SectionList)
{
//Note:必须得用Bytes来实现,StringBuilder只能取到第一个Section
byte[] Buffer = new byte[];
int bufLen = ;
bufLen = GetPrivateProfileString(null, null, null, Buffer,
Buffer.GetUpperBound(), FileName);
GetStringsFromBuffer(Buffer, bufLen, SectionList);
} //读取指定的Section的所有Value到列表中
public void ReadSectionValues(string Section, NameValueCollection Values)
{
StringCollection KeyList = new StringCollection();
ReadSection(Section, KeyList);
Values.Clear();
foreach (string key in KeyList)
{
Values.Add(key, ReadString(Section, key, ""));
}
} /**/
////读取指定的Section的所有Value到列表中,
//public void ReadSectionValues(string Section, NameValueCollection Values,char splitString)
//{ string sectionValue;
// string[] sectionValueSplit;
// StringCollection KeyList = new StringCollection();
// ReadSection(Section, KeyList);
// Values.Clear();
// foreach (string key in KeyList)
// {

public void EraseSection(string Section)
{
if (!WritePrivateProfileString(Section, null, null, FileName))
{
throw (new ApplicationException("无法清除Ini文件中的Section"));
}
} //删除某个Section下的键
public void DeleteKey(string Section, string Ident)
{
WritePrivateProfileString(Section, Ident, null, FileName);
} //Note:对于Win9X,来说需要实现UpdateFile方法将缓冲中的数据写入文件
//在Win NT, 2000和XP上,都是直接写文件,没有缓冲,所以,无须实现UpdateFile
//执行完对Ini文件的修改之后,应该调用本方法更新缓冲区。
public void UpdateFile()
{
WritePrivateProfileString(null, null, null, FileName);
} //检查某个Section下的某个键值是否存在
public bool ValueExists(string Section, string Ident)
{
StringCollection Idents = new StringCollection();
ReadSection(Section, Idents);
return Idents.IndexOf(Ident) > -;
} //确保资源的释放
~IniFiles()
{
UpdateFile();
}
}
}
ini文件注意点:采用此类读取ini文件的时候首行必须空一行
