[C#] 使用 Windows API 讀取 ini 設定檔

專案路徑下新增專案內的
\bin\Debug
裡面新增設定檔 myConfig.ini


using System.Runtime.InteropServices;
using System.IO;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {

        [DllImport("kernel32", CharSet = CharSet.Unicode, SetLastError = true)]
        private static extern bool WritePrivateProfileString(string sectionName, string keyName, string keyValue, string filePath);

        [DllImport("kernel32", CharSet = CharSet.Unicode, SetLastError = true)]
        private static extern int GetPrivateProfileString(string sectionName, string keyName, string defaultReturnString, StringBuilder returnString, int returnStringLength, string filePath);


        public Form1()
        {
            InitializeComponent();

            //取得應用程式的可執行檔路徑，不包括檔名，通常都是位於Debug資料夾
            string Rundir = Application.StartupPath + "\\myConfig.ini";

            //建立ini檔案
            WritePrivateProfileString("Owner", "name", "Dan Mac", @"D:\Temp\myConfig.ini");
            WritePrivateProfileString("Owner", "organization", "Apple Inc.", @"D:\Temp\myConfig.ini");
            WritePrivateProfileString("Database", "server", "192.168.1.100", @"D:\Temp\myConfig.ini");
            WritePrivateProfileString("Database", "port", "50000", @"D:\Temp\myConfig.ini");
            WritePrivateProfileString("Database", "file", "\"db.dat\"", @"D:\Temp\myConfig.ini");


            //讀取ini檔案
            StringBuilder data = new StringBuilder(255);
            GetPrivateProfileString("Database", "file", "NA", data, 255, Rundir);
            Console.WriteLine(data);

        }

    }

}
