1，首先導入命名空間：using System.Runtime.InteropServices;
2，聲明API函數
[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
3,創建ini文件
WritePrivateProfileString("MyQQ", "ID", "798033502", @"C:\QQ.ini");
WritePrivateProfileString("MyQQ", "PWD", "**********", @"C:\QQ.ini");
4，聲明API函數
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
5，讀取ini文件
StringBuilder temp = new StringBuilder();
GetPrivateProfileString("MyQQ", "ID", "賬號錯誤", temp, 255, @"C:\QQ.ini");
string ID = temp.ToString();
GetPrivateProfileString("MyQQ", "PWD", "讀取出錯", temp, 255, @"C:\QQ.ini");
string PWD = temp.ToString();
MessageBox.Show(ID + ":" + PWD);
6完整代碼如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace WindowsFormsApplication1
{
public partial class Main : Form
{
public Main()
{
InitializeComponent();
}
[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
private void button1_Click(object sender, EventArgs e)
{
WritePrivateProfileString("MyQQ", "ID", "798033502", @"C:\QQ.ini");
WritePrivateProfileString("MyQQ", "PWD", "**********", @"C:\QQ.ini");
}
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
private void btnRead_Click(object sender, EventArgs e)
{
StringBuilder temp = new StringBuilder(); www.2cto.com
GetPrivateProfileString("MyQQ", "ID", "賬號錯誤", temp, 255, @"C:\QQ.ini");
string ID = temp.ToString();
GetPrivateProfileString("MyQQ", "PWD", "讀取出錯", temp, 255, @"C:\QQ.ini");
string PWD = temp.ToString();
MessageBox.Show(ID + ":" + PWD);
}
}
}
