我是一个初学者，谁有 c# winform 中用到ini 配置文件的具体例子，发我一份紧用作学习之用，谢谢~

你得先下载一个kernel32.dll然后在你的项目中添加引用
下面是我做过的一个例子，你可以参考一下
public class inifile
{
#region 导入dll函数
[DllImport("kernel32.dll")]
public extern static int GetPrivateProfileIntA(string segname, string keyname, int idefault, string filename);
[DllImport("kernel32.dll")]
public extern static int GetPrivateProfileStringA(string segname, string keyname, string sdefault, StringBuilder retvalue, int nsize, string filename);
[DllImport("kernel32.dll")]
public extern static int GetPrivateProfileSectionA(string segname, byte[] sdata, int nsize, string filename);
[DllImport("kernel32.dll")]
public extern static int WritePrivateProfileSectionA(string segname, byte[] sdata, string filename);
[DllImport("kernel32.dll")]
public extern static int WritePrivateProfileStringA(string segname, string keyname, string svalue, string filename);
[DllImport("kernel32.dll")]
public extern static int GetPrivateProfileSectionNamesA(byte[] vdata, int ilen, string filename);
#endregion
private string _path;
///

/// 所有的设置节
///

public inisegments segments;
///

/// 构造函数
///

/// ini文件路径
public inifile(string vpath)
{
_path = vpath;
segments = new inisegments(this);
byte[] bufsegs = new byte[32767];

int rel = GetPrivateProfileSectionNamesA(bufsegs, 32767, _path);
int icnt, ipos;
string tmp;
if (rel > 0)
{
icnt = 0; ipos = 0;
for (icnt = 0; icnt < rel; icnt++)
{
if (bufsegs[icnt] == 0x00)
{
tmp = System.Text.ASCIIEncoding.Default.GetString(bufsegs, ipos, icnt).Trim();
ipos = icnt + 1;
if (tmp != "")
segments.add(tmp);
}
}
}
}

}
///

/// 要读取的设置节
public void getsegment(inisegment o)
{
byte[] vdata = new byte[32767];
int rlen = GetPrivateProfileSectionA(o.name, vdata, 32767, _path);
o.items.Clear();
if (rlen < 1) return;
string tmp = "";
int ipos, icnt;
ipos = 0;
for (icnt = 0; icnt < rlen; icnt++)
{
if (vdata[icnt] == 0x00)
{
tmp = System.Text.ASCIIEncoding.Default.GetString(vdata, ipos, icnt - ipos).Trim();
if (tmp != "")
{
string[] t = tmp.Split('=');
if (t.Length <= 1)
o.items.add(t[0], "");
else
o.items.add(t[0], t[1]);
}
ipos = icnt + 1;
}
}
}
}
用的时候就直接实例化这个写好的方法类 进行编辑
string COM = new inifile("ini文件地址").segments["分类名称"].items["子项属性"].value
这样就可以获取。
例如：
人（分类名称）
身高（子项属性）=100
体重（子项属性）=55
inifile ini = new inifile("ini文件路径");
ini.setstring("需要修改的分类名", "子项", "值");

我记得有专门操作ini文件的类，我一以前有这样一个DLL文件，去网上搜下吧。

自己去下载一个啊

写一个ini的类：
using System;
using System.Collections;
using System.Collections.Specialized;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Runtime.InteropServices;
using System.IO;

//写INI文件
public static 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 static string ReadString(string Section, string Ident, string Default)
{
Byte[] Buffer = new Byte[200];
int bufLen = GetPrivateProfileString(Section, Ident, Default, Buffer, Buffer.GetUpperBound(0), _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(0).GetString(Buffer);
s = s.Substring(0, bufLen);
s = s.Replace("\0", "");
return s.Trim();
}

//读整数
public static 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 static void WriteInteger(string Section, string Ident, int Value)
{

}
//读布尔
public static bool ReadBool(string Section, string Ident, bool Default)
{

}
catch (Exception ex)

}
}

//写Bool

}

//从Ini文件中，将指定的Section名称中的所有Ident添加到列表中

//Idents.Clear();

//对Section进行解析
GetStringsFromBuffer(Buffer, bufLen, Idents);
}

private static void GetStringsFromBuffer(Byte[] Buffer, int bufLen, StringCollection Strings)
{

if (bufLen != 0)
{
int start = 0;
for (int i = 0; i < bufLen; i++)
{

{
String s = Encoding.GetEncoding(0).GetString(Buffer, start, i - start);
Strings.Add(s);
start = i + 1;
}
}
}
}
//从Ini文件中，读取所有的Sections的名称

}

}
}
//删除某个Section下的键
public static void DeleteKey(string Section, string Ident)

}
//Note:对于Win9X，来说需要实现UpdateFile方法将缓冲中的数据写入文件

//执行完对Ini文件的修改之后，应该调用本方法更新缓冲区。

}

读INI文件：Ini.FileName = Application.StartupPath + "\\aaaa.ini";
要用什么方法可直接调用
