可以通过调用kernel32.dll中的两个api：WritePrivateProfileString，GetPrivateProfileString来实现对ini 文件的读些。
具体实现的代码如下：
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Runtime.InteropServices; //DllImport
using System.Text; //StringBuilder
namespace iniprocess
{
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.TextBox textBox1;
private System.Windows.Forms.Button button2;
private System.Windows.Forms.Button button1;
[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section,
string key,string val,string filePath);
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section,
string key,string def, StringBuilder retVal,
int size,string filePath);
public void IniWriteValue(string Section,string Key,string Value,string filepath)//对ini文件进行写操作的函数
{
WritePrivateProfileString(Section,Key,Value,filepath);
}
public string IniReadValue(string Section,string Key,string filepath)//对ini文件进行读操作的函数
{
StringBuilder temp = new StringBuilder(255);
int i = GetPrivateProfileString(Section,Key,"",temp,
255, filepath);
return temp.ToString();
}
private void button1_Click(object sender, System.EventArgs e)
{
this.textBox1 .Text= IniReadValue("ODBC 32 bit Data Sources","MS Access Database","e:\\temp\\ODBC.INI");
}
private void button2_Click(object sender, System.EventArgs e)
{
IniWriteValue ("ODBC 32 bit Data Sources","MS Access Database",this.textBox1 .Text,"e:\\temp\\ODBC.INI");
}
}
}
