C#创建并读取ini文件

 

1,首先导入命名空间:using System.Runtime.InteropServices;
2,声明API函数
        [DllImport("kernel32")]
        private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
3,创建ini文件
            WritePrivateProfileString("MyQQ", "ID", "798033502", @"C:\QQ.ini");
            WritePrivateProfileString("MyQQ", "PWD", "**********", @"C:\QQ.ini");
4,声明API函数
        [DllImport("kernel32")]
        private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
5,读取ini文件
           StringBuilder temp = new StringBuilder();
            GetPrivateProfileString("MyQQ", "ID", "账号错误", temp, 255, @"C:\QQ.ini");
            string ID = temp.ToString();
            GetPrivateProfileString("MyQQ", "PWD", "读取出错", temp, 255, @"C:\QQ.ini");
            string PWD = temp.ToString();
            MessageBox.Show(ID + ":" + PWD);

        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
